Bump Stop 1-9/16 x 1-5/8 Cone Style Pair

The PROTHANE Bump Stop 1-9/16 x 1-5/8 Cone Style Pair (PTN19-1317BL) is a universal polyurethane suspension component engineered to limit chassis movement and absorb impact energy during extreme suspension compression events. Designed for applications where suspension geometry demands compact, vertical-axis bump limiting, these cone-style stops provide consistent cushioning across repeated high-compression cycles without permanent deformation.

Each bump stop measures 1-9/16 inches in outer diameter and stands 1-5/8 inches tall, sized to fit standard 3/8-inch stud mounts common in frame and axle designs. The polyurethane construction resists oil, grease, and common automotive fluids while maintaining flexibility across temperature extremes—a critical advantage over rubber compounds that degrade or harden. The sold-as-pair format ensures matching compression characteristics across both sides of the suspension system, critical for maintaining symmetric vehicle handling during max-compression scenarios. Weighing just 0.42 pounds per pair, these components add negligible weight while delivering precision bump control.

Off-road enthusiasts, fabricators, and restoration specialists choose PROTHANE bump stops when OEM rubber components fail to survive repeated suspension cycling or environmental exposure. Common applications include lifted truck suspensions, off-road buggies, custom frame-up builds, and any scenario where suspension travel is limited by geometry rather than coil bind. The black finish resists UV degradation and blends into undercarriage areas without requiring additional finishing. Installation requires only basic hand tools and a 3/8-inch mounting stud.
