Fitment for the 1979–1993 Ford Mustang
Listed for the 1979–1993 Ford Mustang, rear position. Check your year, model and trim against the title before you order.
What it does
Bigger or stiffer bars make the car corner flatter and change its balance front to rear. Worn suspension and steering parts show up as clunks, wandering, uneven tire wear and a vague feel; fresh parts restore control, and performance parts sharpen it.
Installation & tips
- Fit new end links and bushings with a new bar, and tighten links with the car at ride height.
- End links: Worn links clunk.
- Bushings: Fresh bushings stop squeaks.
- This part affects how the vehicle stops, steers or holds the road. If you are not sure how to fit it, have it installed or checked by a qualified mechanic.
