Bump Stop 3/4 x 1-3/4 x 1 3/8 Rectangular

The PROTHANE Bump Stop 3/4 x 1-3/4 x 1 3/8 Rectangular is a polyurethane suspension component designed to limit axle travel and absorb impact energy at the extremes of suspension compression and extension. Part number 19-1301, this rectangular bump stop is engineered to prevent metal-to-metal contact between the axle and frame, protecting drivetrain components and vehicle structure during severe articulation, off-road driving, or overloading conditions. The stud-mount design allows secure installation on both front and rear suspension systems across most vehicle platforms.

Prothane polyurethane bump stops offer superior durability compared to rubber alternatives, resisting permanent set and maintaining consistent compression resistance across temperature extremes and prolonged use. The 3/4-inch height, 1-3/4-inch length, and 1 3/8-inch width dimensions accommodate standard suspension geometry on vehicles requiring moderate-travel limiting. The material's damping characteristics progressively compress under load, reducing shock transmission to the chassis and extending suspension component life. Universal fitment means this stop works on both driver and passenger sides, front or rear, wherever suspension mounting points match the provided stud configuration.

Buyers typically choose this bump stop for lifted trucks, off-road vehicles, or vehicles that regularly exceed factory load limits. Suspension geometricians and enthusiasts rely on polyurethane stops to preserve frame integrity during rock crawling, towing, or aggressive articulation where stock rubber components would degrade rapidly. Weighing 0.34 pounds, installation is straightforward for anyone with basic suspension access. This component pairs well with upgrades to shocks, springs, or control arms where end-of-travel protection becomes critical to system longevity.
