Swift Springs Linear Bump Springs – Round Wire
$27.80 $92.65
Swift Springs Linear Bump Springs (Round Wire) deliver the highest measurable shock stroke in the industry, replacing inefficient rubber and foam bump stops with a precision-engineered spring solution. Unlike traditional bump stops that degrade with heat and fatigue, Swift bump springs maintain consistent rate characteristics session after session. These bump springs are an essential upgrade for any performance suspension setup, allowing fine-tuned control over the end-of-travel compression behavior of your dampers. The round wire design delivers a consistent linear rate through the entire stroke range. Swift”s proprietary retainer design fits all bump spring rates, simplifying installation and rate changes at the track.
