Can you tell me about the Powerflex Lifetime Warranty?
Temple Tuning Authorised Dealers Powerflex Lifetime Warranty Applies when you shop with us

Powerflex are proud to offer a Lifetime Warranty on the entire range of products we manufacture.

We have taken this decision because of the confidence that we have both in our products and also in the way that we have handled any warranty issues in the past.

We have never had a time period based warranty policy because we have always treated issues that customers have had as an opportunity to learn.

Where a problem has occurred due to incorrect fitting, we have always asked ourselves if the reason for the error was due to poor fitting instructions.

When we have had a part failure we have tried to understand if the part was being used outside of its design parameters, perhaps on a race car running slick tyres. In cases like this, should we be offering a specific motorsport compound?

Like all manufacturing we have had the occasional material quality issue and in these cases we have always replaced parts without question.

So now we have decided to formalise our open and honest policy and boast about it! 

We will replace any Powerflex product that any customer in the world is unhappy with for any reason.

The only conditions that we attach to this Warranty are:

What we ask in return is that anyone wanting replacement parts contacts us directly and sends as much information as possible which will help us determine the reason for a problem.

Why choose Polyurethane Suspension Bushes?
Polyurethane has been around as a specially designed plastic for over three decades. However recent breakthroughs have now made it possible to engineer unique characteristics into this impressive material. Suspension bushes are amongst the most immensely stressed components installed on a car. They endure tremendous strains and in the most formidable of conditions without maintenance or lubrication.They are made from a rubber compound containing natural products which break down with age. It becomes softer and more pliable, unable to restrain the forces placed on it less and less. This in turn allows more and more movement of suspension parts and offering less control over the suspension geometry.
This results in faster tyre wear, unstable braking and poor handling. This is the single biggest reason you can instantly tell the difference driving a three year old car compared to a showroom new one. However even new cars will benefit from POWERFLEX bushes because of their superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items.
With the technological advances in this material it has been possible to overcome the common problem associated with harder bushes which is increased noise. By correctly engineering the polyurethane compound, bushes can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties. POWERFLEX bushes make sense.
Fitting Powerflex bushes
Potential customers often tell us that they do not feel equipped to fit new parts and that it is a job for professionals. The Powerflex team work very hard to ensure bushes are developed, in general, to be fitted by a home mechanic without hydraulic presses and special tools. The removal of the old parts is often harder than the installation of the new. 
While Powerflex bushes are designed, in the main, so that they can be fitted without special tools sometimes difficulty of removing the old bushes means that if you don't feel you have mechanical experience or tools to do it then we recommend you ask a friend or garage. 

The following video shows how to remove old bushings and a typical Powerflex bush installation

POWERFLEX BUSH INSTALLATION VIDEO

 

FITTING ONE PIECE, DOUBLE FLANGED BUSHES 

1. Take out the factory rubber bush from the arm, clean any dirt and rust from the bore in the arm. Use a round or half-moon file to get rid of any sharp edges from around the bore of the arm creating a small chamfer. Failure to do so will cause impairment to the bush when pressing in.

Removing the original bushings

2. Check the stainless steel sleeve is not in the bush at this point. Apply some washing up liquid to the outside surface of the bush to aid fitting. Press the polyurethane bush into the arm at an angle so one part of the lip is already in the bore of the arm, when the bush is then pushed in the rest of the lip will follow. Make sure the lip has fully popped out the other side of the arm.

3. Apply some of the supplied grease to the bore of the bush and insert the sleeve into the bush. 

4. Re-fit the arm to the car and tighten all hardware to all manufacturers recommended torque settings.

APPLICATION OF GREASE
The grease supplied with our bushes in the sachet is our own formulated PTFE/Silicone bush assembly grease. It’s to be used to optimise bush performance and durability. 

Applying grease to Powerflex bushes

It is best to assemble our bush kits into the suspension components using a small smear of this long lasting grease. This can be applied to the bores and outer flanges of all bushes and to the centre sleeve. Any excess grease visible once assembled can easily be wiped clear. 

What will your bushes do for me?
POWERFLEX bushes promote better road grip and chassis performance by managing the amount of undesired flex in the suspension which increases as rubber bushes degrade. Controlling flex results in your suspension is doing what it was designed for. Your tyres will have greater connection with the road at all times which is great for both safety and performance.  Unlike older technology modern day polyurethane does not result in increased noise and vibration when properly manufactured. 

But I only have a normal family car?
Sometimes customers ask us what is the point in fitting Powerflex technology to a standard car. But here we think our bushings make perfect sense. You can fit them and forget them, they wont wear out. Tyre wear is improved as tyres are correctly contacting with road. Handling is better and most importantly of all safety is improved when tired rubber units are replaced with correctly formulated polyurethane. 

Should I choose Road Series or Black Series Bushes?
It is quite simple really. If your car is driven on the road we recommend choosing Road Series and if it is a used predominantly for competition choose Black Series. Even if your car is a fast road performance model you will still benefit from the better handling and increased grip that your new polyurethane bushes will provide whilst maintaining comfort for everyday driving. It doesn't matter if your car is a family runabout or fast road. If it drives predominantly on the road then we would recommend choosing road series. Unless, you have a modern day classic then you might prefer the more subdued looks of our new heritage range. Just like road series but grey! 

I want to know more about Black Series?
BLACK SERIES are the ultimate performance motorsport, track and race bushes offering the most precise and accurate alignment for your chassis.
Black series bushes are: 80% more resistant, 
25% stiffer and engineered to be the best
The stiffer black series bushes are made from harder compound and are designed for motorsport use only. You might experience extra noise and vibration if your car if fully kitted out in this stiffer compound. These kits are easily identified on our website as the part numbers are the same with the BLK suffix.

Caster, what is it?
Pretty much always positive on everyday cars, caster it is the pivot angle described by the front suspension.

The tyre contact point is behind the theoretic pivot point. Like the contact point of a shopping trolley caster wheel is behind the pivot point.

What is caster on a car? Powerflex explain.
Positive caster gives straight line steering stability and causes a self-centring action to the steering.

Increased positive caster has a number of benefits including: improved dynamic negative camber in turns, greater high speed stability, better road feeling with more steering information through the wheel. By increasing the caster on a road car  we can improve cornering grip as on most cars the effect of caster is to increase dynamic camber throughout cornering. 

What about camber? 
Put simply, negative camber is most celebrated on modern cars and is where the bottom of the wheel is further “out” than the top looking from ahead and compared in the vertical plane.

Older race cars ran positive camber to reduce steering effort and due to their narrow tyres it did not have the effect that it would on cars with modern wider tyres. Whilst we can think of no reason for needing positive camber now, reducing negative camber can be very important.

We manufacture a number of parts to allow camber to be modified on suspension systems where no modification is possible, and it is not always about increasing camber. Increasing negative camber may be beneficial to improve front end grip and turn-in on a track biased car.

However it is not always about performance. Camber adjustment can be needed to correct an imbalance from side to side to reduce tyre wear, and lowering a vehicle can increase negative camber to the point of increasing tyre wear. (A very common problem on the VW Transporter, solved with these bushes)

We manufacture a huge range of parts for many different cars that allow camber adjustment or correction.

From
camber bolts that allow adjustment on fixed McPherson strut suspension, to clever on-car bushes like these Porsche ones, adjustable to allow precise geometry tuning.

If you are ordering camber bolts don't forget our handy little magnetic camber gauge too.

How to measure for Powerflex Anti-Roll bar bushes?
The measurements provided for Powerflex ARB mounts refer to the diameter of your sway bar. Some bars vary in diameter along their length therefore it is often advisable to measure near where the bush sits. A vernier caliper is the best way to measure your bar. However, if you dont have access to a vernier then you can use a closely fitting open-ended spanner to gauge the measurement.

How to know which wishbone bush to choose for my 3 series E46 BMW?
Powerflex make four basic numbers for this bush. 
PFF5-4601 [66mm] - designed to fit the 66mm aluminium bush mounting bracket - that is most standard BMW models!
PFF5-4601-60 [60mm] - designed for the earlier models with 60 bore mounting 
PFF5-4601M3 [60mm] -fits BMW E46 M3 models only
PFF5-4601Xi [60mm] - fits Xi/Xd E46 models only

Hence, if you have any model E46 apart from M3 or Xi/XD then you will need either the PFF5-4601 66mm or the PFF5-4601-60 60mm. You can simply check the size of your housing to see which you need for your car. But we understand that if you are not carrying out work yourself then measuring might not be so easy. Most standard E46 models do use the PFF5-4601 so if you are unsure then buy that one. We offer a 30 days no quibble returns policy if you get it wrong - all we ask is that you return products in same brand new condition as we send them out.


What are the different Powerflex bush colours and all those shore ratings about?
Our bushes are colour coded to make them easy to identify. Take a look below to learn more about the shore rating (durometer) and their general applications.

Red 65A – Used for Universal exhaust hangers and diesel engine mounts.
Yellow 70A – Normally used for engine mounts, differential and subframe mounts or areas where the bush needs extra absorbing properties and movement.
Purple 80A – Our most frequently used material. This is used in most areas of the suspension and provides the perfect mix of performance and compliance.
Black 95A – Our stiffest material. This is used for our Black Series range and sometimes on normal road vehicles where the vehicles suspension needs us to use this hardness of material i.e. in areas of high stress and load. 
Powerflex different bush colours and shore ratings
I have purchased road series bushes so why are they black? Have I been sent the wrong bushes?
Some areas of the car's suspension are under extra stress and load. Even on normal road vehicles sometimes the suspension requirements will mean that a black shore compound is best suited. In these instances the bushes in your pack will be black in colour. Road series bushes are traditionally associated with purple colour but in fact they can be yellow, red, purple or black dependent on where they are to be fitted on the vehicle and the task that is required of them.

How do I know if my suspension bushes need replacing?
Suspension bushes are among the most stressed components on a car. They not only have to deal with every bump in the road and vehicle vibration they also suffer from engine heat, friction heat, contamination on the road/from the vehicle and lack of lubrication. With age rubber bushes deteriorate, they may become dry and cracked and lose their noise/vibration absorbing properties. Bushings are located on suspension / chassis components where metal arms or parts make a joint. Bushes act to avoid the stress and friction of metal surfaces grinding on each other. 

Bushes are generally located on the car's ball joints, control or wishbone arms, engine or transmission mounts, shock absorbers, steering rack, tie rod, rear beam mounts, rear axle and other suspension to chassis components.

Typically a worn bush may become noisy on uneven or gravely roads, it may make a clunking sound on corners or when braking, the vehicle may suffer vibration and the steering may feel sloppy or less precise. The bush may lost its noise and impact absorbing properties. Just like ageing human joints where cartilage has worn down resulting on with bone on bone, metal on metal can cause excessive wear and tear.

Unlike rubber bushes, polyurethane bushes do not deteriorate with age and are impervious to heat and contamination. You can fit and forget them because they won't wear out. 

What do engine mounts do?
Engine mounts are the parts responsible for keeping the engine of a car firmly attached to the chassis. They perform the function of mounting the engine and absorbing engine noise. Tired or degrading mounts can result in disproportionate noises from engine bay, excessive vibrations or engine movement. This can result in stress on other components on the motor. 
Unlike rubber mounts Powerflex polyurethane bushes with not degrade over time and secure engine thereby providing a fit and forget solution to the problems caused by factory mounts. 
Powerflex have a range of engine mounts such as these standard replacements for MG ZT through to these clever adjustable engine mounts for BMW
