Overview

Once again Steeda has paved the way for you to take your Mustang to the next level with the Adjustable Bumpstop Kit. Designed and engineered in-house specifically for the S550/S650 Mustang, these bumpstops are made from high-impact polyurethane, which makes them stiffer than the factory and prevents damage to the shocks, and other suspension components. The adjustable feature gives the customer the ability to use the kit on a stock or lowered ride height vehicle. This means no trimming of the factory bumpstops in order to maintain a safe and quality ride on lowered vehicles.

For the track. It is not recommended to use these bumpstops on the street. They are designed for use on smooth track surfaces and will provide better handling when cornering. When installed properly and set at the correct height for your springs, the handling of your Mustang is more predictable.

Works with all stock shocks and struts EXCEPT GT350 MagneRide (NOTE: The shocks on the Performance Pack (PP) models have a smaller diameter shaft. Our bumpstops will work, but they will not fit as tight.) Retains stock boots.

Key Benefits

Prevents damage and fatigue to the shocks

First-hand note

FFP fits Steeda parts every week in Thousand Oaks.

— Why we stock Steeda

OE-style engineering, in-house manufacturing, race-proven on Steeda's own SCCA program.

Steeda has been engineering Mustang — and now Explorer, Focus, F-150, and Maverick — parts in Valdosta, Georgia since 1988. CNC-machined billet, proprietary CAD-driven suspension geometry, and a factory SCCA Majors road-racing team that runs their own parts on the track every weekend. When you bolt a Steeda part onto your car, it's the same part Steeda's own race cars run.

We carry Steeda because the fitment is right the first time, the warranty is real (lifetime on Steeda-manufactured parts), and the install instructions don't leave you guessing. Drop the car at our Thousand Oaks shop and our techs handle the fit-up — or order with confidence and run it yourself.
