    Features & Details

    • Original Equipment on 2013 "Boss 302S" Race Car

    • Improves Handling
    • Adjustable
    • Perfect with Other Suspension Mods
    • Fits All 2005-2014 Mustangs
    BOSS 302S Original Equipment. This Ford Racing Bumpsteer Kit is the same exact one found as standard original equipment on the 2013-2014 Mustang BOSS 302S race car.

    Improves Handling. Eliminate bumpsteer by correcting your Mustang's front end suspension geometry with Ford Racing's BOSS 302S fully adjustable kit. Replace your stock, non-adjustable components and gain better, more predictable cornering and handling even at the limit.

    Adjustable. Ford Racing's fully adjustable kit provides a wider range of adjustment than other kits to allow you to fine-tune your suspension for improved steering response and crisp cornering.

    No Drill Installation. Unlike other kits which require you to drill your spindle out during installation, Ford Racing's Bumpsteer kit features spherical rod-ends with tapered shafts for an easy installation with no drilling.

    Application. This Ford Racing BOSS 302S Bumpsteer kit is designed for all 2005-2014 Mustangs, including the V6, GT, Bullitt, BOSS and Shelby GT500 models.

    NOTE: Bumpsteer is a change in toe angle caused by the suspension moving up or down. Bump-steer is built into the geometry of the suspension and steering system, and has nothing to do with turning the steering wheel. The effect of bumpsteer is for the wheel to toe-in or toe-out when the suspension moves up or down. This toe change or "steering" occurs any time the suspension moves, whether it is from body roll, brake-dive, or hitting a bump in the road. Bump steer is undesirable because the suspension is steering the car instead of the driver. To fix a bumpsteer problem, you need to alter the height of the outer tie-rod relative to the steering rack with adjustable tie-rod ends, also known as a bumpsteer kit.

            Bumpsteer Kit

            Better ride with stock Tie Rod Ends. Car has been modified by Shelby in Las Vegas. Now it is a Shelby GTS

            Great part

            Very easy to install. These should be stock on all GT's. They tighten up the steering instantly, great product.

            That's right. These adjustable tie rod ends came in a box with a MM sticker with a FRPP sticker on top of that. They also came with MM instructions. Look at the pic. This is a MM bumpsteer kit. That said, they are super nice. Very well made. I had these installed with GT500 LCAs w/Prothane bushings and Steeda X5 balljoints. Awesome!!
