KSP PERFORMANCE Upper Control Arms 2–4" Lift Tubular Black for 6-Lug GM 1500 — 1.25" DOM, PU Bushings

KSP PERFORMANCE Upper Control Arms are heavy-duty replacement A-arms that lift compatible 2007–2018 GM 1500-series trucks and SUVs by 2–4 inches while improving suspension strength and alignment capability.

These upper control arms are engineered as direct-fit upgrades for many 6-lug Chevrolet, GMC and Cadillac 1500 models from 2007 through 2018. Built from 1.25" DOM tubing with TIG welds and a coated finish, they replace factory cast or forged steel arms on compatible vehicles to provide extra ground clearance, a more aggressive stance and longer-lasting bushings and ball joints. The updated design includes polyurethane bushings, extended dust covers, CNC-machined components and a pre-greased service approach to reduce early wear.

Which vehicles and wheel patterns are compatible with these arms?

These control arms are intended for GM 1500-platform trucks and SUVs with 6-lug wheels and specific original equipment upper arms. Confirm your model year and OE arm type before ordering to ensure fitment.

• Fits many 2007–2014 Yukon/Yukon XL and 2007–2018 Sierra/Silverado 1500 models (check OE forged/cast arm requirement).
• Compatible with 2007–2014 Avalanche, Tahoe, Suburban and 2007–2014/2014–2018 Silverado New Body where noted.
• Also fits 2007–2014 Cadillac Escalade 2WD/4WD models with 6-lug hubs.

How do these arms perform and resist wear compared to stock arms?

KSP PERFORMANCE arms use DOM tubing and TIG welding to increase structural integrity versus many factory cast parts. Improved components reduce flex, the PU bushings resist deformation, and longer dust covers help keep contaminants out for extended life.

• 1.25" DOM tubing for higher strength and fatigue resistance.
• TIG-welded joints for reliable, reinforced construction.
• PU bushings and longer dust covers to improve durability and service life.

What lift and alignment effects should I expect after installing these A-arms?

These arms are designed to provide a 2–4" lift range depending on your vehicle and combined suspension components. They correct upper control arm geometry for lifted setups, helping maintain proper camber and caster when used with compatible leveling or lift kits.

• 2–4" lift capability when paired with appropriate suspension parts.
• Improved camber/caster positioning for lifted applications when used with compatible lowers and struts.
• CNC-machined ball joint components for consistent alignment and fitment.

What maintenance and warranty notes matter before purchase?

The ball joint arrives pre-greased and generally doesn’t require extra lubrication within the first year. Use care when servicing the grease zerk to avoid damage, and follow the brand’s after-sales options for replacements or refunds if fitment issues arise.

• Do not overtighten the zerk during greasing to prevent breakage.
• New ball joints usually require no additional grease for up to 12 months.
• KSP offers a 12-month ball-joint replacement policy plus 30-day refund or free replacement parts service beyond one month.

Who is this for: These control arms suit owners of 2007–2018 GM 1500 trucks and SUVs with 6-lug hubs who want a reliable 2–4" lift solution that retains OEM mounting points. They’re a good match for installers and enthusiasts seeking stronger tubular construction, improved bushings, and a factory-compatible upgrade for lifted street or light off-road use. Verify your vehicle’s model year, OE arm type (forged/cast), and lug pattern before ordering to ensure a correct fit.
