KSP PERFORMANCE Front Upper Control Arms for Chevy Silverado & GMC Sierra 1500 (2019-2026) — 2-4in Adjustable, 3 Ball Joints

KSP PERFORMANCE Front Upper Control Arms replace the factory arms on 2019–2026 Chevy Silverado 1500 and 2019+ GMC Sierra 1500, providing a 2–4" lift-compatible, adjustable suspension solution with heavy‑duty ball joints and factory‑like ride feel.

These aftermarket upper control arms are engineered to correct caster and ball joint geometry after a lift, restoring predictable steering and reducing premature tire wear. Built from thickened, CNC‑machined alloy steel with TIG welding and a corrosion‑resistant powder coat, they combine durability with OE-like rubber bushings for comfortable ride characteristics. The units include three heavy‑duty ball joints and are designed to fit Trail Boss, AT4 and AT4X variants with modest lifts.

How do these control arms improve driving after a suspension lift?

The KSP front upper control arms realign the spherical joint angles and caster that change when you raise your truck, restoring proper steering geometry. That makes handling more predictable, reduces uneven tire wear, and helps preserve factory steering response while allowing lifted fitment.

• Restores caster and ball joint angle after 2–4" lift
• Reduces premature shoulder wear on front tires
• Improves steering predictability and tracking

What materials and construction ensure these arms are durable?

Each arm uses thickened tubing with CNC machined joints and high‑frequency heat‑treated alloy steel ball studs for superior strength compared with stock units. Seam quality is reinforced by TIG welding and the entire assembly receives an outdoor‑grade powder coat to resist corrosion and extend service life in harsh conditions.

• High‑frequency heat treated alloy steel ball studs for longevity
• CNC machined components for precise fit and alignment
• TIG welded seams and durable powder coat finish for corrosion resistance

How does the fit and installation work for modern Silverado/Sierra models?

These UCAs are designed specifically for 2019 and newer Chevy Silverado 1500 and GMC Sierra 1500 trucks, including Trail Boss/AT4/AT4X models with 1.5–2" of lift note. An adaptive ride control bracket is built into the arm to simplify installation without cutting. Follow vehicle compatibility checks and installation guidance for the best results.

• Direct fit for 2019+ Silverado 1500 and 2019+ Sierra 1500
• Adaptive ride control bracket included — no cutting required
• New ball joints pre‑lubricated; no extra grease needed within first year

What maintenance and support should owners expect?

The ball joints are shipped pre‑greased and do not require additional lubrication for approximately one year. Regular inspections of bushings and joints are recommended, especially after off‑road use. KSP PERFORMANCE offers a 30‑day refund window and a 12‑month replacement policy to back the product.

• Pre‑greased ball joints — low initial maintenance
• Inspect bushings, joints, and mounting hardware periodically
• KSP support: 30‑day refund and 12‑month free replacement

Who is this for? These KSP PERFORMANCE front upper control arms are intended for Silverado and Sierra owners who have lifted their 2019–2026 1500 trucks by 2–4 inches and want to restore correct suspension geometry and driving confidence. They suit enthusiasts seeking a heavy‑duty, serviceable aftermarket upgrade that keeps a factory‑like ride feel while offering stronger ball joints, robust construction and an easier installation path for models with adaptive ride control systems.
