Stock Replacement Rear S tainless Steel Brake Lin

The Rough Country Stock Replacement Rear Stainless Steel Brake Line (part number 89330S) is a DOT-approved, PTFE-lined braided stainless steel brake hose kit engineered for lifted Ford full-size trucks and SUVs from 1980–1996. This rear brake line replacement addresses the critical challenge faced by 4WD owners who install 4- to 6-inch suspension lifts: factory brake lines become stretched and dangerously overstressed, risking rupture under braking load. Rough Country's stainless steel construction resists corrosion and heat degradation while the braided outer layer provides abrasion protection in the underbody environment.

The PTFE (polytetrafluoroethylene) inner lining ensures brake fluid compatibility and consistent pressure delivery across the full temperature range of both street and off-road use. DOT approval confirms this line meets federal safety standards for brake system performance, a non-negotiable requirement for any vehicle that carries passengers. The stainless steel braiding guards against UV damage, road salt exposure, and abrasion from suspension components—a practical consideration for vehicles operated in harsh climates or frequently off-road. At 0.6 lbs and dimensioned to fit the rear axle routing of lifted Ford platforms, this replacement line integrates seamlessly into suspension packages where factory hoses no longer reach safe lengths.

This kit is essential for serious 4WD enthusiasts and off-road builders who have lifted their full-size Ford trucks or SUVs and need to restore proper brake line geometry. It eliminates the risk of flex-related brake line failure that occurs when lifting kits stretch factory hoses beyond their design limits. Rough Country specializes in suspension and brake system upgrades specifically for lifted 4x4 applications, making this rear brake line a purpose-built solution rather than a generic aftermarket alternative.
