Bump Spring Round Wire

The Bump Spring Round Wire (SBS8000) is a heavy-duty suspension component engineered for vehicles requiring maximum load capacity and consistent bump absorption. With an 8000 lb/in spring rate, 2.25-inch free length, and 2-inch outer diameter, this coil spring is built to handle extreme compression cycles common to off-road recovery, towing, and high-payload applications. The round wire construction paired with a durable copper powder coat finish delivers corrosion resistance and longevity in harsh field conditions.

Specifications define real-world performance. The 8000 lb/in spring rate means this bump stop spring resists compression under heavy load while preventing metal-to-metal contact between suspension components. The steel construction with copper powder coat protects against rust and wear in salt spray, mud, and high-moisture environments. At 0.93 lbs with compact dimensions (3.3 x 3.3 x 4.7 inches), it integrates easily into tight suspension packages without adding unnecessary weight. This is a single-unit replacement, making it ideal for users performing progressive spring or suspension rebuild work.

Off-road operators, heavy-vehicle technicians, and suspension tuners rely on precision bump stops to maintain ride quality during extreme articulation and load shifts. The SBS8000 is specified for vehicles where standard spring rates prove insufficient—work trucks towing near maximum capacity, off-road buggies with aggressive suspension travel, and recovery vehicles handling shock loads. Operators who understand suspension geometry recognize that bump stops prevent bottoming and damper damage, directly extending drivetrain lifespan and improving predictability under stress.

Bump stop springs are measured by free length, outer diameter, and spring rate—each specification must match your vehicle's suspension design. The 8000 lb/in rate places this component in the heavy-duty category, suitable for vehicles with factory spring rates of 700+ lb/in. Cross-reference your suspension documentation or consult a technician to confirm fitment before ordering.
