This is a set of polyurethane bushings for the REAR INNER bushing on the lateral links of the GD-chassis Subaru WRX/STI.
Powerflex bushings are made from polyurethane so they flex far less than the squishy stock rubber bushings. Stiff bushings mean more precise alignment, better suspension control, and better steering feel.
Note that it is the nature of polyurethane to squeak eventually. Lubricating them periodically will reduce this tendency, but we will not take back any polyurethane suspension product because of noise.
Part #5 in the diagram. Note: This is just a single pair of bushings. If you want to replace ALL the lateral link bushings, you will also want THIS KIT, which has the other six bushings.
Fits all 2002-2007 Subaru WRX and WRX STI.
