Chevy II Bolt-On Coil-Over Conversion


The VariShock product line offers an affordable and versatile, high-end performance improvement over OEM replacements and traditional twin-tube shock absorbers. Our updated design overcomes the major shortcomings of traditional gas shocks and low-end twin-tube shocks. Varishocks provide a more usable adjustment range and response curve, improved heat dissipation, and lightweight billet-aluminum construction. VariShocks are available for most applications including coil-overs, struts, bolt-in OEM replacements, and shockwave air ride systems.
