The Bump Stop Spring 1100lb (model ST1100) is a vital suspension component designed for vehicle builds where precision ride height control and maximum suspension travel are essential. It is particularly beneficial for lifted trucks, lowered sports cars, and custom off-road platforms.
This bump stop spring compresses under extreme suspension extension to prevent metal-to-metal contact between the chassis and axle housing. With a spring rate of 1100 lbs/inch, it provides a balance between compliance and support for mid-to-heavy-duty applications. Its compact design (2.7 × 2.2 × 3 inches) allows for installation in tight suspension geometry without interfering with brake lines or driveshafts.
Mechanics and suspension technicians recommend the 1100lb bump stop spring for vehicles equipped with lowering springs, air suspension systems, or extended-travel off-road setups. Its lightweight construction of 0.41 lbs minimizes unsprung weight, which is crucial for suspension tuning. This spring maintains consistent dampening characteristics across temperature extremes and high cycle counts, making it a reliable choice for performance-oriented applications.
