Strange Engineering has been the leader in driveline and suspension for over 50 years. Strange Engineering lightweight aluminum coil-over shocks are built with proven technology that has been relied on by racers for years. Tuning the suspension is made easy by a conveniently located adjuster knob(s) at the bottom of the shock body. The wide range of valving allows each shock to be adjusted to changing track conditions quickly and easily. Available in both single and double adjustable configurations, these shocks can also be customized to specific lengths, strokes and valving by Strange Engineering. The S1413 spanner wrench is the perfect complement for the shocks, allowing you to make spring adjustments quickly and easily. Don’t just race… Race Strange!
