Proudly made in the USA, DuroBumps premium bump stops feature dual durometer (hardness) rubber to provide smooth, progressive dampening that greatly reduces hard bottom-outs, allowing for greater control and comfort compared to OEM bump stops, which can feel rock-hard on contact. DuroBumps eliminates the inchshell-shock inch effect experienced with OEM bump stops.
The DuroBumps DBR525 is the equivalent of using a 2 inch block spacer with OEM bump stops. The DBR525 limits wheel-up travel by 2 inch compared to OEM bump stops and is designed for trucks with a rear lift of 2 inch or more (fully loaded).
(For lifts less than 2 inch we offer a 3.5 inch version DBR354R)
Features and benefits
- Improved handling - Dual durometer rubber allows DuroBumps to act as a secondary coil spring, with smooth engagement that progressively increases compression load.
- Mounts in OEM location - Easily bolts into the OEM location, ensuring a proper fit with no modifications.
- No loss of up travel - Direct OEM replacement with no loss of suspension/wheel-up travel.
- Reduced tire rub - Reduced wheel-up travel means less tire rub in the wheel wells and less driveshaft contact on the OEM gas tank skid.
- Increased suspension life - Greatly extends the service life of other suspension components by absorbing the shock load from suspension bottom-outs. DuroBumps absorb the impact, saving critical suspension components from excessive wear and extending service intervals to the shocks, upper and lower control arm bushings, and panhard bar bushings.
- Small, compact, application specific - DuroBumps bump stops are designed to fit specific truck models. No universal fit spacers required.
- Smooth and silent - Unlike Hydro bumps, DuroBumps are whisper quiet on contact.
- Premium bump stops - DuroBumps are proudly made in the USA from the highest quality raw materials.
- Provided mounting hardware - JIS 10.9 zinc-coated hex head metric bolts and single-use thread locker are provided with every set of DuroBumps to ensure a strong, secure fit.
