Couldn't load pickup availability
Powerflex suspension bushes for the Mitsubishi Lancer Evolution X CZ4A (10/07 - 05/16) are polyurethane replacements for the original rubber bushes. They are available in Road Series and Black Series, with a fitting diagram showing every bush position and part number.
Overview
Rubber suspension bushes soften, split and let the suspension move out of position as they age. Powerflex polyurethane bushes control that unwanted flex, which keeps the Mitsubishi Lancer Evolution X CZ4A's suspension geometry where it should be. Powerflex says this prolongs tyre life, improves performance and increases safety on the road. Every bush is made in-house by Powerflex, a UK manufacturer formed in 1996.

Frequently asked questions
Which Powerflex range should I choose for my Mitsubishi Lancer Evolution X CZ4A?
Road Series suits road and fast-road use. Black Series uses a firmer 95 Shore A compound for track and motorsport. Choose the range that matches how you use the car.
Are Powerflex bushes covered by a warranty?
Powerflex offers a lifetime warranty to the original purchaser when bought through an authorised distributor. Parts used for track, motorsport or competition, and part numbers ending in BLK (Black Series), are excluded. Source: Powerflex lifetime warranty terms. Checked 9 November 2026.
Will polyurethane bushes make the ride harsher?
Polyurethane is firmer than rubber, so you will feel the car respond more directly. Road Series kits use different compounds for different positions, from 65A to 95A, to balance control with comfort. Black Series is the firmest at 95 Shore A.
How do I know which bushes I need?
Use the fitting diagram for your chosen range. It numbers every bush position on the Mitsubishi Lancer Evolution X CZ4A and gives the matching Powerflex part number, so you can replace a single worn bush or the whole set.
Is there anything to check before ordering?
Yes. Read the fitment notes above, as some parts only fit certain years or specifications of the Mitsubishi Lancer Evolution X CZ4A.
