3-1/8in BUMP STOP SET

The Energy Suspension 3-1/8in Bump Stop Set (Part 9.9143R) is a polyurethane suspension component engineered to limit chassis compression and control vehicle ride height under load. Sold as a matched pair, these bump stops feature a 2.438-inch outer diameter, 0.375-inch inner bore, and 3.125-inch nominal height—dimensions optimized for suspension geometry across a wide range of applications. The red polyurethane compound provides consistent compression resistance while absorbing impact energy, making this set essential for vehicles operating at aggressive ride heights or carrying heavy payloads.

Energy Suspension's Hyper-Flex polyurethane formulation is designed for durability and temperature stability across street and track environments. The bolt-on installation method allows straightforward integration into existing suspension systems without specialized tools. The 1.12-pound set weight reflects the lightweight characteristics of polyurethane construction, which does not absorb road salt or moisture like rubber alternatives, making it particularly suited for vehicles exposed to marine environments or aggressive weather. These bump stops are universal fitment, meaning they adapt to a wide range of suspension architectures through proper positioning and fastening.

Off-road enthusiasts, lifted truck owners, and suspension tuners rely on quality bump stops to protect chassis and suspension components from bottoming out on obstacles or during hard landings. This set is appropriate for vehicles running lowered setups seeking to prevent contact with the frame, or lifted platforms where additional compression travel limits are required. Polyurethane bump stops like this Energy Suspension set maintain consistent performance across temperature swings—a critical factor for vehicles regularly transitioning between cold climates and hot pavement.
