Spring 1.5in ID Bump x 3.6in Tall

The Spring 1.5in ID Bump x 3.6in Tall is a professional-grade bump stop spring engineered to manage suspension articulation and protect vehicle components from hard bottoming impacts. Designed by Eibach, a leader in suspension technology, this spring is essential for vehicles requiring supplementary cushioning during extreme compression, off-road use, or high-load applications. The 3.6-inch free length and 1.5-inch inner diameter configuration makes this component ideal for custom suspension builds, lifted trucks, and performance vehicles where progressive spring rate control is critical.

Built from durable steel and finished with a red powder coat for corrosion resistance, the Spring 1.5in ID Bump x 3.6in Tall delivers a 1000 lb/in spring rate—offering firm resistance that activates during full suspension compression. This stiff spring rate prevents metal-on-metal contact, extends suspension component lifespan, and improves ride quality by absorbing final-stage impacts that primary springs cannot alone manage. The powder-coated finish ensures long-term protection in harsh environments, maintaining structural integrity whether exposed to moisture, salt, or extreme temperature fluctuations common in tactical, off-road, or heavy-use scenarios.

This bump stop spring is ideal for off-road enthusiasts, truck owners, and suspension specialists seeking to upgrade stock damping systems with reliable secondary compression control. The lightweight construction at 0.952 lbs allows easy installation within existing suspension geometry, while the compact 3 x 3 x 6-inch dimensions fit standard suspension mounting brackets. Proper installation alongside primary springs and dampers ensures smooth articulation during trail use, heavy loading, or extreme suspension extension, making this component essential for anyone prioritizing suspension durability and vehicle protection.
