KSP PERFORMANCE Upper Control Arms 2-4" Lift for 2007-2016 GM 1500 6-Lug Trucks & SUVs — Tubular 1.25" DOM Red

KSP PERFORMANCE Upper Control Arms are reinforced, tubular replacement A-arms designed to lift and restore correct front suspension geometry on 2007–2018 GM 1500 trucks and SUVs with 6-lug wheels.

If you need a robust, direct-fit upgrade to accommodate a 2–4" lift while maintaining wheel alignment and ride stability, these upper control arms are built to address the extra stress taller suspensions introduce. Constructed from 1.25" DOM tubing with TIG welds and fitted with updated polyurethane bushings and improved dust covers, they pair modern strength with user-focused refinement. The arms are finished in textured red (black shown as option) for corrosion resistance and a sporty look while supporting OE forged/cast steel arm configurations on compatible models.

Which models and years will these control arms fit?

These upper control arms are intended for GM 1500-series trucks and SUVs that use 6-lug wheels and OE forged/cast steel upper arms. They cover a broad range of model years but check the OE arm style before ordering.

• Fits: 2007–2014 Cadillac Escalade (2WD/4WD)

How do these arms improve suspension performance after a 2–4" lift?

Raising a truck alters control-arm geometry and increases loads on joints and bushings. KSP PERFORMANCE arms restore more favorable geometry and use tougher materials to resist bending and premature wear, helping maintain predictable steering and tire contact under higher ride heights.

• 1.25" DOM tubing resists flex under heavier loads
• TIG welding provides stronger, more consistent welds compared with MIG
• Updated PU bushings reduce compliance for crisper steering feedback
• CNC-machined surfaces ensure proper fit and alignment

What installation and maintenance details should I know?

These are bolt-on replacements that use factory mounting points for a straightforward swap. The ball joints come pre-filled and do not require additional grease for the first year; follow the included zerk-fitting guidance to avoid damage and ensure long-term serviceability.

• Tighten grease zerk carefully after servicing; avoid excessive force
• New ball joint: no extra grease needed within first year
• Inspect mounting hardware and torque to factory specs during install
• Recommended wheel alignment after installation to restore proper toe and camber

What warranty and post-purchase support does KSP PERFORMANCE provide?

KSP PERFORMANCE backs these control arms with practical coverage and clear after-sales steps if components develop issues. Their policies aim to limit downtime and ensure replacement parts are available when needed.

• 12-month free replacement for defective ball joints
• 30-day refund option; free replacement parts beyond one month
• Customer support available for fitment questions and problem resolution
• Quality control: updated dust covers and PU bushings for longer service life

Who is this for: These upper control arms are intended for owners of compatible 2007–2018 GM 1500-series trucks and SUVs who have installed a 2–4" lift or plan to, and who want a stronger, direct-fit arm that restores proper steering geometry and withstands demanding use. They suit off-road enthusiasts, daily drivers upgrading suspension durability, and technicians needing a reliable replacement with solid warranty backing.
