Highest Measurable shock stroke in the industry.

Swift linear bump springs offers the highest measurable shock stroke in the industry. Unlike inefficient rubber and foam bump stops, Swift Bump Springs are fatigue and heat resistant. 

Our bump springs are an essential upgrade for performance minded individuals yearning to maximize suspension tune ability. And, to keep things simple, our engineers developed a proprietary retainer which seamlessly fits all spring rates.
