Daystar Coil Spring Bump Stops

Bump stops are a critical component of any well-engineered suspension system — preventing damaging over-compression and eliminating the harsh bottoming-out that occurs during aggressive off-road driving, competitive racing, and demanding everyday use. Daystar's Coil Spring Bump Stop lineup is designed and tested under the most rigorous conditions to deliver consistent stopping power without deflection, backed by decades of proven polyurethane expertise.

Key Features:

• High-Impact Polyurethane Construction: Manufactured from premium polyurethane that delivers increased strength, reduced deflection under load, and long-lasting resistance to heat, UV exposure, oil, and moisture — outperforming factory rubber bump stops in every measurable way.
• Wide Range of Styles and Applications: Available in a variety of application-specific and universal configurations — from low-profile to bullet-shaped to pyramid competition-style — to accommodate virtually any suspension setup or build requirement.
• Protects Shocks and Coil Springs: By preventing over-compression and cushioning suspension travel, Daystar bump stops serve as a first line of defense that helps extend the service life of shocks and springs.
• EVS Foam Technology (Select Models): Select models feature Daystar's proprietary EVS (Energy Absorption System) microcellular foam material, which delivers a true progressive spring rate — functioning as an active suspension component rather than a simple hard limiter, with a rate that increases as the foam compresses.
• Made in the USA: All Daystar products are manufactured at their facility in the United States and are trusted by off-road enthusiasts, competitive racers, and daily drivers worldwide.

EVS Foam Technology — Progressive, Next-Generation Performance:

Select models in this lineup feature Daystar's proprietary EVS (Energy Absorption System) Foam technology. Unlike conventional bump stops that function as simple hard limiters, EVS Foam stops use a microcellular foam material engineered to provide a true progressive spring rate. The resistance increases as the material compresses, making these stops an active part of the suspension rather than a passive limiter. Engineered to withstand thousands of compression cycles without degrading, EVS Foam models are well-suited for competitive racing, recreational off-roading, and demanding daily use alike.
