Race-Only Alignment Range for Serious GM Full Size Builds
The SPC Performance 92054 Pro Series front adjustable upper control arm is built for GM full size trucks and SUVs running aggressive lift, lowered stance, or larger tire and wheel packages that push factory alignment specs out of range. SPC92054 is labeled Race Only, meaning it is intended for off-road, race, or closed-course applications where extreme camber and caster adjustment is needed beyond what is street legal or DOT approved. This control arm restores proper geometry so alignment specs can be dialed in on heavily modified suspensions.
Key Features
- Wide range adjustable camber and caster correction
- Race Only application for extreme suspension setups
- Pro Series billet or tubular construction for durability
- Restores proper alignment geometry on lifted or lowered trucks
- Direct bolt-in design for factory mounting points

Control Arms
Control arms are the key suspension linkages that connect the wheel hub and knuckle assembly to the vehicle frame, controlling wheel travel through both compression and droop cycles. Worn OEM control arms with loose ball joints or deteriorated bushings cause vague steering, tire wear, and handling inconsistency that only go away with replacement or upgrade.Popular UpgradesTubular steel upper control arms for lifted trucks and SUVs are the most popular upgrade in the control arm category, correcting the geometry compromised by a suspension lift and restoring proper caster angle and ball joint centering. Adjustable upper control arms allow alignment angles like caster and camber to be dialed in precisely after a lift or lowering modification. Replacement lower control arms with polyurethane or solid aluminum bushings improve response and longevity compared to worn OEM rubber mounts.Why do I need new control arms after a lift kit?A suspension lift changes the angle at which the OEM upp...

Suspension
Aftermarket suspension systems improve handling, ride quality, and ride height adjustment beyond what the factory suspension provides. From lowering springs and coilover kits for sport handling to lift kits and leveling kits for truck and SUV off-road capability, quality suspension components transform how a vehicle rides and handles. Popular Suspension Upgrades Popular suspension upgrades include coilover kits for adjustable ride height and damping, sport lowering springs for improved handling and reduced body roll, performance shock absorbers and strut assemblies, sway bar and end link upgrade kits, subframe brace kits, and complete suspension packages for lifted trucks and off-road SUVs. Alignment kits including camber bolts and camber arms are also frequently ordered after ride height changes. What is the difference between coilovers and lowering springs? Coilovers are complete shock and spring assemblies with adjustable ride height set by threading the spring perch on the shock...
