These insert into the rear two bushings in the rear subframe for vehicles with variant code RA02 or RA03. Vehicles with variant code RA01 have bushings that do not have insertable voids.

Powerflex Street Purple and Yellow bushings are 10-30% stiffer than OEM rubber in most applications. Powerflex Racing Black bushings are approx. 80% stiffer than OEM and are denoted by BLK at the end of the part number. Both are designed to last the life of the vehicle. Powerflex products feature a proprietary design that does not need to be re-lubed once installed. Note: Powerflex has superseded some numbers so that the only available bushing is black. These are for applications where the bushings tested to not increase NVH and a softer version was not needed
