TC Upper Control Arms – Maximize Off-Road Performance and Control
When lifting the front of your vehicle for better off-road performance, upgrading to aftermarket coilovers is just the first step. To truly unlock the full potential of your suspension, upgrading your Upper Control Arms (UCA) is essential. Adding 2-3" of lift can throw off your factory alignment, but these TC UCAs are engineered to restore proper alignment and improve performance in challenging terrain.
With an additional 3 degrees of caster, these UCAs deliver better straight-line tracking, enhanced high-speed stability, and sharper cornering. Designed specifically to work with extended travel coilover shocks, these arms provide an impressive 1" of added droop wheel travel, giving you that crucial extra articulation off-road. Built from 4130 chromoly steel, these arms are designed for durability and are fully bolt-on, making installation straightforward.
The CNC tapered spindle adapters convert the factory ball joints to a 1" uniball setup, maximizing strength and wheel travel. Additionally, urethane bushings help reduce deflection for more precise steering control. With the ability to work with all aftermarket shocks and even fit 3.0" diameter coilover shocks with no contact, these UCAs are the go-to choice for serious overlanders. Whether you're tackling rocky terrain or high-speed desert runs, these control arms are crafted to handle the toughest conditions.
