KSP PERFORMANCE Adjustable Upper Control Arms for Toyota Tacoma/Prerunner 2-4 inch Lift — Greaseable Ball Joint, Powder-Coated

KSP PERFORMANCE adjustable upper control arms replace factory fixed arms to restore correct suspension geometry and steering alignment on lifted 1995–2003 Toyota Tacoma, Prerunner, and 1995–2002 4Runner N180 models.

These aftermarket upper control arms are engineered to work with 2–4 inches of lift, offering a stronger, adjustable alternative to stock fixed arms. Built from cold-drawn steel with powder-coated protection and a greaseable flexible ball joint, the assembly corrects axle camber and caster after lift installations while resisting corrosion and road debris. They arrive pre-assembled for straightforward installation and include polyurethane bushings for improved handling and longevity.

How do these arms correct suspension geometry on a lifted Tacoma or Prerunner?

The adjustable length and angled design reposition the upper suspension mounting point to bring camber and caster back into spec after a lift. Adjustment lets you fine-tune alignment without dropping the control arm or re-welding brackets. The flexible, greaseable ball joint accommodates increased travel and reduces binding common with stock fixed arms.

• Adjustable threaded tube for precise length setting to match 2–4" lifts
• Flexible greaseable ball joint with dust boot to maintain movement and flush contaminants
• Pre-set geometry to reduce required alignment corrections after installation

What makes the KSP ball joint and mounting hardware more durable than stock?

KSP PERFORMANCE uses high-frequency heat-treated alloy steel for the ball pin and thicker cold-drawn steel tubing for the arms, increasing resistance to impact and fatigue. A powder-coated finish fights rust and corrosion, while a pre-installed dust boot and grease zerk help keep contaminants out and lubricant in. The ball pin includes a hex hole for easier installation and servicing.

• Heat-treated alloy steel ball pin for improved strength
• Powder coat to prevent corrosion in wet or salty conditions
• Greaseable socket plus dust boot for extended joint life and serviceability

How difficult is installation and what vehicle years/models fit these arms?

Installation is straightforward for experienced home mechanics or professional shops: remove the factory upper arm, install the KSP arm, set preliminary length, and complete alignment. The arms are designed as direct-fit replacements for specified model years but always confirm compatibility with your exact year and drivetrain before purchase.

• Fitment: 1996–2003 Toyota Tacoma 4x4, 1996–2004 Toyota Prerunner 4x2, 1995–2002 Toyota 4Runner N180 4x4
• Pre-assembled with dust boots and bushings to speed install
• Requires alignment after installation for optimal handling

What maintenance is required to keep these control arms performing well?

Periodic greasing through the zerk fitting will prolong ball joint life—do not over-tighten the zerk when servicing. New ball joints don’t need extra grease within the first year if properly lubricated at manufacture, but annual inspection and lubrication thereafter helps prevent premature wear. Check mounting hardware and bushings during routine service to ensure fasteners remain torqued to spec.

• Tighten zerk fitting gently after greasing; avoid excessive force
• Do not add grease to new ball joints within the first year if not required
• Inspect dust boots and bushings for tears or compression during axle checks

Who is this for? KSP PERFORMANCE adjustable upper control arms are intended for owners of older Toyota Tacoma, Prerunner, and 4Runner N180 models who have installed a 2–4" lift and need durable, serviceable components to restore proper suspension geometry and improve steering feel. They suit DIY mechanics who perform alignments or professional shops upgrading lifted trucks for reliable on- and off-road performance. KSP provides a 30-day refund and 12-month replacement support—confirm fitment before purchasing to ensure correct application.
