Overview

Do you want more from your Mustang’s rear suspension? Are you after better handling on the street and at the track? Steeda’s Pro-Action Double-Adjustable Rear Shocks are designed to give you more adjustability, greater control, improved traction, and lower times!

Proven performance. Steeda has extensively tested and tuned these rear shocks, proving their capabilities with our record-breaking Silver Bullet. These shocks are not limited to the dragstrip, though. The valving allows for excellent adjustability, and these will be a step up from single adjustable rear shocks if you are looking for an upgrade on your autocross or HPDE S550.

Superior technology. These dampers are packed with more advanced technology than other adjustable shocks in this price range. When adjusted, the oil flow is controlled at the piston for a 100% range of motion. Other brands use needle valves that can limit adjustability and narrow the adjustment range. Rebound damping is adjusted at the shock’s top and stiffened by turning the adjuster counter-clockwise. Compression damping is adjusted at the bottom of the shock and is stiffened by turning the adjuster clockwise.

Fitment

Note: If your shock is adjusted to full stiff or full soft, it is recommended that you turn it back about 1/16th of a turn to prevent jamming the adjuster.

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.
