WHY
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 limit performance without upgrading the Upper Control Arm too.
Our UCA's are designed to add caster - offering better straight line tracking, as well as improved high speed stability and cornering. TC upper arms add component durability and allow for individual parts to be replaced including bushings and uniballs.
Designed to maintain factory alignment specs on vehicles with 1.5"-3" lift kits.
1" I.D. uniballs feature a heat-treated stainless-steel ball & heat-treated stainless-steel race for maximum corrosion resistance and component longevity. These uniballs also feature a military grade PTFE woven fabric liner that helps prevent noise and reduce maintenance.
CNC tapered spindle adapters convert the factory ball joint to a 1" uniball for easy installation.
Custom profile upper and lower hi-misalignment spacers are machined from 17-4 stainless-steel to maximize strength and wheel travel.
Urethane bushings reduce deflection compared to stock rubber bushings.
4130 chromoly tubular upper control arms are 100% bolt on.
Control arm pivots include zerk fittings to grease the bushings and inner sleeves without disassembly.
3 stage powder coat process includes a durable clear coat to provide a long-lasting finish.
Complete Grade 8 hardware kit is included.
Hand crafted in the U.S.A.
Upper control arms fit 2019 thru current model year (2025) Silverado and Sierra 1500 trucks.
Important: TOTAL CHAOS aftermarket parts and supplied components have been engineered around the design of a factory chassis and related suspension components. Cross installing some aftermarket combinations of equipment may cause conflicts in fitment, and can cause geometry changes that were not designed or intended by TOTAL CHAOS. This can result in vehicle alignment issues, contact issues with other components, improper fitment issues, or cause accelerated wear and tear on some parts. TOTAL CHAOS can not guarantee that our suspension systems and accessories are compatible to be installed with another brands aftermarket equipment.
