KSP PERFORMANCE Adjustable Upper Control Arms for Silverado Sierra 2500/3500 — 2-4in Lift, Textured Black Pair, PU Bushings

KSP PERFORMANCE 2"–4" adjustable tubular upper control arms are a heavy-duty replacement set engineered to restore correct suspension geometry for 2000–2010 Chevy Silverado and GMC Sierra 2500/3500 HD trucks after a 2–4" lift.

These upper control arms provide a robust, adjustable connection between the vehicle frame and front suspension, improving ball joint alignment and caster angle after a lift. Built from 1.25" DOM tubing with TIG welding and CNC-machined components, this pair (left and right) is finished in textured black and ships with upgraded PU bushings, longer-life dust covers, and replaceable ball joints. They are designed to fit a range of heavy-duty GM trucks and certain Hummer H2 models, and come with a parts and refund policy backed by KSP PERFORMANCE customer support.

How do these control arms fix alignment issues after lifting my truck?

Raising a truck shifts suspension geometry, often increasing the angle that causes premature ball joint wear and steering pull. Adjustable upper control arms let you re-center the ball joint and set proper caster/camber to bring handling back towards factory intent. Using the built-in adjustability reduces stress on factory components and helps maintain predictable steering response.

• Adjustable length to correct caster and camber after a 2–4" lift
• Replaceable ball joints to restore correct pivot points
• PU bushings reduce deflection compared with stock rubber
• Works with aftermarket lifts and OEM-style installs

What materials and construction features ensure durability?

These arms use 1.25" DOM steel tubing for superior strength and concentricity compared with mild tube, and TIG welding for stronger, cleaner welds at load-bearing joints. Critical surfaces are CNC machined for precise fitment, and the textured black finish offers corrosion resistance while matching lifted-truck aesthetics.

• 1.25" DOM tubing for high torsional strength
• TIG welding for reinforced structural joints
• CNC-machined mounting faces and threads for accurate alignment
• Durable textured black finish to resist corrosion

How do the upgraded bushings and ball joints improve ride and maintenance?

PU bushings deliver firmer control than standard rubber, reducing unwanted movement without creating harshness associated with solid mounts. The kit’s ball joints include dust covers and zerk fittings for greasing, extending service life; KSP PERFORMANCE also provides a ball joint replacement warranty and guidance on proper greasing practice.

• Polyurethane bushings for improved steering feel
• Longer dust covers to protect against contaminants
• Zerk grease fittings—tighten after greasing, avoid over-torquing
• 12-month ball joint replacement warranty from KSP PERFORMANCE

Who is this for: These control arms are aimed at truck owners and professional installers who have lifted 2000–2010 Silverado or Sierra 2500/3500 HD trucks (and compatible H2 riders) by 2–4 inches and need a durable, adjustable upgrade to restore alignment, reduce premature wear, and improve steering control. If you want stronger tubing, serviceable ball joints, and polyurethane bushings for firmer handling without replacing the entire front suspension, this kit offers a cost-effective solution backed by KSP PERFORMANCE support.
