2010-2024 5th Gen 4Runner Total Chaos Upper Control Arms (UCA)

Lifting the front of a vehicle with a set of coilovers may be step one in gaining more off-road performance, however installing just an aftermarket shock can cause limitations without upgrading the Upper Control Arm too.Adding 2-3'' of lift on the vehicle will compromise your Toyota's factory alignment specs from lost caster. Our UCA's are designed to add 3 degrees of caster - offering better straight line tracking, as well as improved high speed stability and cornering. TC UCA's are designed to provide 1'' of added droop wheel travel when they are installed with a pair of factory replacement ''extended travel'' coil over shocks. TC upper arms add component durability and allow for individual parts to be replaced including bushings and uniballs. UCA's are designed with added caster to aid in retaining factory alignment specs when aftermarket lift kits are installed. This reduces the darting or wandering in the vehicle's steering when 2.5" -3" lift kits are installed. Upper control arm
