Delrin upper control arm bushings for 1999-2004 Mustang Cobra IRS reduce wheel hop and improve handling.

Replaces the stock rubber bushings with non-deflecting Delrin to eliminate one of the causes of wheel hop, while also improving handling by maintaining dynamic alignment settings.


Included are tools to make installation easy. You really don't want to try installing Delrin control arm bushings without the MM tools. The tools make installing Delrin much easier than installing urethane control arm bushings. These MM-designed tools are the ones that others copy.

New design makes installation easier.

Contrary to claims made by a competing company, we found that the root cause of excessive play in the upper control arm bushings was not caused by wear of the Delrin bushing, but by improper installation of the shims used to locate the upper arm fore and aft. While we like the precise adjustment provided by the shims, it seems that the care needed for proper installation eluded some people. Our new design has no shims, eliminating any possibility of excessive fore/aft play caused by improper installation of the shims.
