KSP PERFORMANCE Upper Control Arm for Silverado/Sierra 1500 — Stage 2.0 2007–2018 2–4" Lift Tubular DOM with PU Bushings

KSP PERFORMANCE Stage 2.0 tubular upper control arm replaces OE stamped arms on 2007–2018 Silverado/Sierra 1500 and similar GM 6‑lug trucks to support 2"–4" lifts with stronger DOM tubing, updated bushings, and a longer‑life dust cover.

This upper control arm is a direct-fit aftermarket upgrade designed to replace factory stamped‑steel or aluminum arms on many GM 1500 trucks and SUVs with 6‑lug wheels. It’s built from 1.25" DOM tubing with reinforced MIG welds, CNC machining and a textured finish, and it includes PU bushings and a pre-greased ball joint to improve durability and handling for lifted applications.

How does this arm improve handling on a 2"–4" lifted Silverado?

The tubular design and stronger materials resist flex better than OE stamped pieces, keeping alignment geometry more stable under load. Upgraded polyurethane bushings reduce unwanted deflection compared with softer factory rubber, which helps steering responsiveness and tire wear.

• 1.25" DOM tubing increases torsional strength for lift setups
• MIG welding for reinforced joints and consistent integrity
• PU bushings reduce compliance and improve feedback
• Preinstalled ball joint with dust cover for extended service life

Will these arms fit my truck and what models are supported?

These KSP upper control arms are made for GM 6‑lug 1500 platforms from 2007–2018 and slip into the OE mounting points without major frame modification. Confirm 6‑lug wheel configurations and model years before purchase to ensure compatibility.

• Fits: 2007–2018 Yukon, Yukon XL 1500, Sierra 1500, Tahoe, Suburban 1500, Silverado 1500
• Also fits: 2007–2013 Avalanche 1500 and 2007–2014 Escalade (6‑lug)
• Designed for 2"–4" lift heights with 6‑lug wheel setups
• Direct bolt‑on to OE mounting points — check wheel lug pattern first

What maintenance or installation notes should I know before buying?

Install like a standard control arm swap using factory hardware or supplied hardware where indicated, then torque to manufacturer specs. The ball joint comes pre-greased; do not over‑grease, and avoid overtightening the grease zerk to prevent damage.

• Tighten zerk fittings carefully after greasing; avoid excessive force
• New ball joints do not require additional grease within the first year
• Follow factory alignment after installation to prevent abnormal tire wear
• Inspect welds, bushings and dust cover periodically for road wear

What warranty and support does KSP PERFORMANCE provide?

KSP backs this control arm with a 12‑month replacement for the ball joint and a customer service policy that includes 30‑day refunds and free replacement parts beyond the first month. Support options are available if parts arrive damaged or if fitment questions arise.

• 12‑month free ball joint replacement
• 30‑day refund policy; free replacement parts after 30 days if needed
• Customer support for fitment and installation inquiries
• Durable finishes and CNC machining for consistent quality

Who is this for: drivers and mechanics upgrading late‑model GM 1500 trucks and SUVs with 6‑lug wheels who want a stronger, longer‑lasting upper control arm for 2"–4" lifts. It’s suited for owners seeking better steering feel and reduced arm flex compared with OE stamped steel or aluminum units, and for shops doing lifted suspension builds that require reliable, serviceable components.
