KSP PERFORMANCE Upper Control Arms for Silverado/Sierra 1500 2007-2018 6-Lug Tubular 2-4" Lift, 1.25" DOM & Poly Bushings

KSP PERFORMANCE Upper Control Arm Stage 2.0 is a direct-replacement tubular arm engineered to fit 6-lug 2007–2018 Silverado/Sierra 1500 trucks and Yukon family vehicles with 2–4" lifts for improved strength and handling.

This upper control arm set replaces OE stamped components with 1.25" DOM tubular construction, CNC-machined surfaces, and upgraded polyurethane bushings to give lifted trucks a more durable front-end geometry. The arms are built for 6-lug applications across Chevy and GMC full-size models from 2007–2018 and come as an updated version with longer-lasting dust covers, MIG-reinforced welds, and a textured red finish for a rugged look. KSP backs the kit with a 12-month ball joint replacement policy plus a 30-day refund or free replacement-parts program.

Will these arms fit my 2007–2018 Silverado or Sierra with a 2–4" lift?

Yes — the kit is specifically designed for 6-lug wheel models of Silverado and Sierra 1500, plus similar GM SUVs and trucks listed in the fitment table. It replaces OE stamped steel or aluminum arms while preserving proper steering geometry for 2–4" suspension lifts.

• Fitment covers 2007–2018 Sierra and Silverado 1500 (6-lug only).
• Also compatible with Yukon, Yukon XL, Tahoe, Suburban, Avalanche (specific years noted).
• Supports both 2WD and 4WD drivetrains on covered models.

How are these upper control arms constructed and upgraded?

KSP Stage 2.0 arms use 1.25" DOM tubing and reinforced MIG welds for greater structural rigidity than OEM stamped parts. CNC machining ensures accurate mounting surfaces, while the polyurethane bushings and improved ball joint dust covers extend service life and driving performance.

• 1.25" DOM tubular body for superior strength and fatigue resistance.
• MIG welding reinforcement delivers consistent, robust joints.
• CNC-machined components and red textured finish for fit and corrosion resistance.
• PU bushings and longer-life dust covers to reduce wear and noise.

What maintenance and installation notes should I follow?

Install like-for-like with factory hardware, torque fasteners to manufacturer specs, and observe the zerk fitting guidance to avoid damage. New ball joints typically do not require additional grease in the first year; if you regrease, tighten the zerk gently to avoid breaking the copper fitting.

• Avoid excessive torque on the zerk grease fitting to prevent breakage.
• Do not add extra grease to brand-new ball joints within the first year.
• Check alignment after installation to restore proper tire wear and handling.

What warranty and after-sales support does KSP provide?

KSP includes a 12-month free ball-joint replacement policy and a customer-friendly return program. If you request a return within 30 days, you can get a refund; after that window, KSP offers free replacement parts to resolve problems quickly.

• 12-month replacement for ball joint components.
• 30-day refund policy for buyer satisfaction.
• Ongoing support and replacement parts beyond the initial month.

Who this is for: This upper control arm kit is intended for owners of 2007–2018 Chevy and GMC 6-lug 1500 trucks and equivalent SUVs who run 2–4" suspension lifts and want a stronger, longer-lasting alternative to stamped OE arms. It suits drivers upgrading suspension durability for off-road use, heavier loads, or those simply replacing worn factory components with a robust tubular solution that improves front-end stability without extensive modification.
