These washers have a different depth than the factory strut top plate washers. They engage the rubber bushings all the time, giving the car a much firmer feel, and eliminating the "pogo" effect that many users complain about after installing lowering springs. These also work well with the GMPP handling kit for further ride improvement. Combined with our Strut tower bars, you'll have that show quality look under the hood.
Sold as a pair.
