Product Details

Enhance chassis rigidity and improve steering precision with the ultra-strong PERRIN Rear Shock Tower Brace.

During cornering, the PERRIN Rear Shock Tower Brace improves chassis rigidity, enhances steering precision under high load conditions, and reduces understeer. Through tension and compression, the PERRIN brace transfers the load of each shock tower to the opposing strut tower, reducing flex by tying them together. Tire wear and metal fatigue in the shock tower area can be reduced.

Precision constructed using CNC-machined aluminum feet and tubing, the PERRIN Rear Shock Tower Brace is strong while remaining lightweight. The feet are two-piece assemblies made from machined aluminum and anodized black. The two pieces are held together around the bar with black oxide stainless steel hardware.

Lighter, stronger, and stiffer than aluminum tubing, our diagonal woven carbon fabric is rolled to form a 100% carbon fiber hollow bar. The feet are two-piece assemblies made from machined aluminum and anodized black. The two pieces are held together around the bar with black oxide stainless steel hardware.

The bar is powder coated for protection against the elements and the finish will look awesome for years to come. The feet are anodized black and lasered with the PERRIN logo.

Check fitment before you order. We publish fitment from manufacturer and industry data and take care with it, but fit can depend on trim, cab and bed configuration, factory options and any modifications already on your vehicle. If you are unsure, contact us before ordering — and if fitment we published turns out to be wrong, we cover the return.
