DuroBumps Rear Bump Stops are designed to provide smooth, progressive dampening, significantly reducing hard bottom-outs and enhancing control and comfort compared to OEM bump stops, which can be harsh on impact. These premium bump stops eliminate the “shell-shock” effect experienced when hitting OEM bump stops. Proudly made in the USA, DuroBumps feature dual durometer (hardness) rubber, ensuring a soft initial contact with increasing firmness as they compress.

The DuroBumps 3.5-inch bump stop is slightly taller than OEM bump stops, designed to compress under load and absorb impact before reaching the ultimate stop, without limiting wheel-up travel. Ideal for stock-height trucks and mild lifts up to 2 inches (fully loaded). For lifts over 2 inches, the 4.25-inch bump stop variant is available.

Features:

• Improved Handling: Dual durometer rubber acts as secondary coil springs, providing smooth engagement that progressively increases compression load predictably.
• Mounts in OEM Location: Easily installs under the U-bolts in the same location as OEM bump stops, ensuring proper fit with no modifications required.
• No Loss of Up Travel: Direct OEM replacement without sacrificing suspension/wheel-up travel.
• Increased Suspension Life: Absorbs shock load from suspension bottom-outs, extending the service life of shocks and leaf-pack bushings.
• Application-Specific Design: Custom designed for specific truck models, eliminating the need for “universal-fit” spacers.
• Smooth and Silent Operation: Unlike hydro bumps, DuroBumps are whisper-quiet upon contact.
• Premium Quality: Made in the USA from high-quality raw materials.
• Provided Mounting Hardware: Includes powder-coated steel mounting plates and JIS 10.9 zinc-coated hex head metric bolts and nuts.
