With many classic cars getting hold of original parts is becoming increasingly difficult with supply dwindling or worse, parts being discontinued altogether. 
The factory KONI rear shock absorbers are no exception. The rubber mounting bushes wear and perish, leading to vague handling or unwelcome knocks and clunks so we have added these Rear Shock Lower Bushes to the range. 
Made in our classic Grey 95A durometer material to retain that OE look, our bushes help to restore handling feel, with longevity backed by our Lifetime Warranty. They are also the perfect accompaniment to our PFR57-413 Rear Shock Upper Mounting Bush.
Replacing your car rubber suspension bushes with Polyurethane Suspension Bushes will give you:

About Powerflex Polyurethane Bushes

Powerflex Polyurethane Bushes

At Design911, we offer a dedicated range of Powerflex polyurethane bushes for Porsche models, ideal for owners looking to refine suspension feel, upgrade tired rubber and get more out of their suspension upgrades without compromising everyday usability.

Powerflex Bushes backed by a Lifetime Warranty

Powerflex are proud to offer a Lifetime Warranty on the entire range of products they manufacture. Soft, ageing or cracked rubber bushes allow unwanted movement in the suspension, which can lead to imprecise handling, uneven tyre wear and instability under braking or cornering. Powerflex polyurethane bushes are engineered to control this movement far more consistently than tired rubber, giving a more precise, repeatable feel.

Why do Porsche Powerflex Polyurethane Bushes matter?

Polyurethane bushes sit at the heart of your Porsche’s suspension, controlling how components move relative to each other. As original rubber bushes age, they soften, split or deform, allowing geometry to change under load. This can leave the car feeling vague and less composed, even if major parts such as dampers and springs are in good condition. Upgrading key locations to Powerflex bushes helps the suspension maintain its intended alignment for longer, complementing other suspension upgrades and giving the chassis a more tied-down feel in everyday driving.

  • Keep your Porsche feeling tight and controlled rather than loose or vague
  • Help suspension and steering geometry stay more consistent under braking and cornering
  • Reduce annoying symptoms from worn bushes such as clunks, instability and uneven tyre wear
  • Support long-term enjoyment, especially on upgraded or enthusiast-driven Porsche models

Common options & kits

Individual replacement bushes

Specific bushes for one arm or location, ideal when you have identified a particular weak point or MOT advisory and want a targeted improvement.

  • Good for solving a localised knock, movement or alignment issue
  • Lets you improve high-stress points first (for example front control arm or anti-roll bar bushes)
  • Useful when building up a full suspension refresh in stages

Matched axle sets or pairs

Powerflex bushes supplied in sets so both sides of the axle are renewed together, keeping behaviour consistent left to right.

  • Balanced feel and response across the car
  • Helps avoid uneven wear or geometry from a mix of new and tired bushes
  • A sensible choice when refreshing the front or rear suspension as a package

Complete bush packages

Grouped kits covering multiple arms and mounting points, popular for full suspension upgrades, restorations or track-focused builds.

  • Brings tired suspensions back to a tight, precise feel in one hit
  • Ensures related bushes are matched in material and stiffness
  • Ideal when combining with new dampers, springs, anti-roll bars or other Porsche suspension upgrades

Brands available in this category

For this category we stock a wide choice of trusted brands for Porsche models. You can also browse and filter by brand on this page to focus on your preferred manufacturers.

Kits

Design911 offers an extensive selection of package deals for Porsche parts, providing an ideal solution for enthusiasts looking to upgrade, maintain or personalise their Porsche. These kits can include complementary components around the bushes, helping ensure compatibility and convenience when planning a suspension refresh.

Powerflex

Powerflex is a specialist in polyurethane suspension and chassis components, manufacturing in a dedicated UK facility. Their Porsche bushes are designed to combine durability with carefully chosen stiffness levels, so you can select options that suit fast-road, daily use or more focused applications, all supported by their Lifetime Warranty.

When should you review or replace your Porsche Powerflex polyurethane bushes?

Checking bushes and considering polyurethane upgrades goes hand in hand with wider Porsche suspension work. Even if the car still passes an MOT, aged rubber components can hold back the benefit of new dampers, springs or anti-roll bars.

  • You notice clunks, knocking, or a loose feeling through the chassis over bumps
  • The car feels vague on turn-in, wanders on the motorway or needs frequent steering correction
  • Uneven tyre wear or repeated alignment changes suggest geometry is not being held accurately
  • You are upgrading other suspension parts and want the underlying bushes to match the sharper setup

If any of these apply, it is a good time to assess your existing bushes and consider where Powerflex polyurethane could offer a worthwhile improvement for your Porsche.

Explore Porsche Powerflex polyurethane bushes with Design911

Browse Powerflex polyurethane bushes for Porsche at Design911 – from individual replacements for problem areas to more comprehensive bush packages that support full suspension upgrades. Use the filters by model, location and brand to pinpoint the right components for your Porsche build.
