Specs At A Glance

Good To Know

Q: How do I know if my rear suspension springs need replacing? A: Sagging ride height, a skid that bottoms out easily, or coils that no longer hold tension are the common signs. Checking free length against a fresh spring confirms the wear.

Q: Will these fit both the 1990 and 1991 Indy 400? A: They are listed to cover both years of the Indy 400 rear suspension. Fit can still depend on serial number and build variation, so confirm your machine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
