Wheel hop or traction issues? We have the solution! Optimize your vehicle's instant center and improve forward traction by lowering the rear of the lower control arm and adding heavy duty control arms. UMI’s anti-hop kit is designed to increase traction during launch and reduce unwanted wheel hop. Choose 2”, 2-3/4” or 3-1/4” drop to optimize vehicle handling and traction. UMI’s anti-hop kit installed can provide an average 0.10 second (or better) 60-foot reduction and an overall improvement in launch consistency. Anti-hop kit relocation brackets are constructed of a combination of 1/4” and 3/16” CNC laser cut steel plate for ultimate strength and high horsepower applications. The included box control arms are machined from 1”x 2” boxed steel tubing and feature greaseable polyurethane bushings. Anti-hop kit is designed to work on both lowered and non-lowered vehicles and feature multiple settings to optimize vehicle handling and traction.
