KSP Upper Control Arm for Sierra Silverado 1500 2007-2018 - Tubular

In this review of the KSP Upper Control Arm for Sierra and Silverado 1500 (2007-2018), the bottom line is clear: this is a heavy-duty tubular replacement aimed at drivers who want stronger, more durable upper arms for a 2-4' lift while keeping close to OE geometry. The reviewer found it best for DIY installers and shop pros working on 6-lug trucks who value a beefier tubular 1.25 DOM construction and an updated Stage 3.0 bushing package. The single biggest reason to consider these arms is the reinforced welds and updated PU bushing that improve driving feel compared with stamped steel arms.

Key Features

• Fitment Coverage: Direct fit for many 2007-2018 GM 1500 platforms with 6-lug wheels, meaning a straightforward swap for compatible trucks.
• Construction: Built from 1.25 DOM tubing to provide stronger resistance to bending and better longevity than thinner stamped steel alternatives.
• Welding and Strength: MIG welding and reinforced joints are intended to give a more stable, reinforced structure under load for lifted applications.
• Stage 3.0 Upgrades: PU bushings and a longer-life dust cover are designed to improve handling response and reduce early wear.
• Service Promise: 12-month free ball joint replacement and a 30-day refund window with free replacement parts after one month provide practical after-sales support.

Who It's For

This control arm is for owners of 2007-2018 Yukon, Sierra, Silverado and similar GM 1500 trucks who run 6-lug wheels and are lifting their truck 2-4' or replacing worn OE stamped steel or aluminum arms. It suits mechanically confident DIYers and professional installers who appreciate tubular strength and the updated PU bushing for improved driving feel.

Drivers who need perfect OE ball joint angles for advanced alignment settings or those with 5-lug conversions should look elsewhere. Also, if long-term bushing durability under extreme off-road abuse is the top priority, consider alternatives with a longer proven field history or different bushing compounds.
