KSP PERFORMANCE Upper Control Arms for Silverado/Sierra 2011-2019 — 2-4" Lift, Pair, Black Tubular Adjustable

KSP PERFORMANCE adjustable tubular upper control arms replace factory arms to restore alignment, improve suspension geometry, and safely accommodate 2–4" lifts on 2011–2019 Chevy Silverado/Sierra 2500HD and 3500HD (8-lug).

These tubular, CNC-machined upper control arms are built to replace worn or limiting stock arms after a suspension lift. They use polyurethane bushings, reinforced TIG welds and upgraded ball joints to maintain correct caster and camber angles while extending service life and reducing deflection under load. Finished in a durable double-layer black coating with blue accents, the arms are sold as a pair and engineered specifically for 8-lug models of Silverado/Sierra heavy-duty trucks from 2011 through 2019.

How do these control arms improve handling after a 2–4" lift?

After raising the ride height, stock upper control arms often create poor alignment and accelerated tire wear. KSP’s tubular design restores more factory-like suspension geometry so steering feel and tire contact patch are more consistent. The stiffer PU bushings reduce unwanted movement while the precision ball joint retains smooth articulation.

• Restores caster and camber ranges lost with lift.
• Reduces lateral deflection for firmer steering response.
• PU bushings dampen vibration without excess compliance.
• CNC machining ensures diameter tolerances for consistent fit.

What materials and construction features increase durability?

KSP upper arms combine thick-walled tubular steel with TIG welding and protective coatings to resist fatigue and corrosion. The dust covers and upgraded ball joints are designed for longer service life, while the polyurethane bushings resist deformation better than stock rubber. A double-layer paint and blue finish provides additional rust protection and a clean appearance.

• TIG-welded joints for stronger, more consistent seams.
• Durable dust covers extend ball joint life against contaminants.
• PU bushings for improved load handling and longevity.
• Double-layer finish for superior rust resistance and visual appeal.

Will these arms fit my truck and what installation notes should I follow?

These arms are made specifically for 2011–2019 Chevy Silverado 2500HD and 3500HD and 2011–2019 Chevy Sierra 2500HD and 3500HD, 2WD or 4WD, but only for vehicles equipped with 8-lug wheels. They are sold as a pair and designed to replace factory upper control arms when using a 2–4" lift. Follow the included fitment guide and torque specs during installation; take care when greasing the zerk fittings and avoid over-tightening to prevent damage.

• Compatibility: 2011–2019 Silverado/Sierra 2500HD & 3500HD (8-lug only).
• Sold as a pair: driver and passenger side included.
• Zerk fittings: tighten carefully and do not over-torque; no extra grease required for new ball joints within one year.
• Professional alignment recommended after installation.

What aftermarket support and warranty does KSP provide?

KSP PERFORMANCE offers post-purchase support and a straightforward return policy to protect your investment. The listing includes a 30-day refund window plus a 12-month free replacement coverage for defects, and KSP advises verifying year/make/model compatibility before ordering. Their support team can assist with fitment questions and replacement procedures if needed.

• 30-day refund policy for returns.
• 12-month free replacement for manufacturing issues.
• Customer support to confirm compatibility and troubleshoot fitment.

Who this is for: These upper control arms are aimed at owners of 2011–2019 Chevy Silverado and Sierra 2500HD/3500HD trucks with 8-lug wheels who have installed a 2–4" lift or plan to do so, and who want stronger, longer-lasting suspension components. Ideal buyers include off-roaders, work-truck operators, and enthusiasts seeking improved alignment control, reduced bushing wear, and robust TIG-welded construction. If you need arms tailored to non-8-lug models or different years, verify fitment or consider alternative KSP products before purchase.
