This shock tower brace centers use a 1/8� formed, steel center for added strength. The shock tower braces can be used with factory style shock and spring setups as well as with coilover conversions and coilover, rear suspension kits. Shock tower braces are black powdercoated for additional corrosion resistance, and deliver a show quality finish. This kit is low profile and will clear stock and most aftermarket exhaust systems. Made in the U.S.A.
