Lock In Precise Rear Axle Location Under Load
The factory upper trailing arm on the Ram 2500 relies on soft rubber bushings that break down over time, allowing the rear axle to wander under load and reducing overall stability. This Whiteline KTA480 upper trailing arm assembly replaces the worn factory component with a stronger design that keeps the axle located precisely during towing and hauling.
Key Features

- Reduces axle wander under heavy payload and towing
- Improves rear end stability and handling confidence
- Built stronger than the factory stamped steel arm
- KTA480 uses the factory mounting points for a direct fit

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...
