Chassis Tuning - Poly Bushes

Powerflex Polyurethane Bush Kits

Once the springs and dampers have been sorted, we believe the next most beneficial area for attention is the bushes. They are made to be flexible to some extent to absorb harshness, but as they age the original rubber loses its 'tone' and gets slacker. This allows the suspension system to move relative to the chassis so the car's handling and response become less sharp. The grade of polyurethane used in our uprated bushes is not so hard as to cause undue harshness, however they provide a big improvement over standard and they keep their 'tone' much longer than the original rubber, so the effect lasts longer.
Fast Road Poly bushes are manufactured in hardness levels from 70 to 85 Shore A to be noticeably stiffer than factory bushes.

Kits are available as Front and Rear axle sets, or as individual bushes if required. Typically, a Front Axle Set includes the wishbone or track control arm and anti-roll bar bushes and a Rear Axle Set comprises rear beam bushes.

Unlike the original bushes, Polyurethane Bushes require no special tools to fit and are therefore a DIY proposition - or we can fit them for you if you prefer.

Powerflex Black Series Suspension Bushes

There are a number of applications where chassis performance is the only consideration. For the ultimate in performance Powerflex introduce The Black Series. A new range of bushes developed for Race, Rally and Circuit use. Powerflex Black Series bushes are manufactured using a 95 Shore A compound to provide maximum control of chassis geometry. This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than the purple performance material which is 80 Shore material.

Engine Bed/Subframe Bushes - Astra G/H and Zafira A/B

Poweflex have engineered a solution to replace the factory engine bed/subframe bushes in Astra G/H and Zafria A/B which can be prone to failure and contribute to vague handling. These stiffer engine bed bushes help improve the front end feel of the car especially during turn-in and cornering. By removing the flex in the subframe bushes the handling is improved giving a more positive feel to the front end.

These Front Subframe Bushes feature two polyurethane top-hat style bushes that makes for simple installation and durability. The bushes house a stainless steel sleeve and are supported by zinc coated steel washers at each end for increased support under load.

Poly bushes will be resistant to corrosion and the addition of a stainless steel sleeve should help prevent the bed bolts from seizing into the bushes, which can happen with the factory bushes.

Suitable for Astra G, Astra H, Zafira A and Zafira B All Models.

These new bushes replace OE part numbers 90498689, 9223022, 9223023 and 13107328 used across the model ranges.

The application of corrosion resistant materials, robust design and the Powerflex Lifetime Warranty ensures the subframe need not be removed again once fitted, unless removal is required for other service work to be carried out.

These bushes are available in Purple Series 80 Shore Road Spec material for vehicles that are mainly used on the road and also Black Series 95 Shore Track Spec material that suits vehicles being used in Motorsport or predominantly on the track.

Purple: £22.20 each Black: £24.42 each

6 bushes required per subframe.

Professional installation is recommended. The ideal time is when the subframe is removed to allow access to the gearbox or clutch.
