KSP PERFORMANCE Adjustable Upper Control Arms for Tacoma & 4Runner 2-4" Lift — Greasable Flexible Ball Joint, Heavy-Duty Steel

KSP PERFORMANCE adjustable upper control arms replace factory fixed arms to correct suspension geometry after a 2–4" lift on Toyota Tacoma, 4Runner N180 and Prerunner models.

These aftermarket upper control arms are engineered to restore proper wheel alignment, increase suspension articulation, and reduce premature wear on tires and ball joints after a lift. Built from thickened cold-drawn steel with a powder-coated finish, CNC-machined tubing and a greasable flexible ball joint, they combine durability with serviceability for lifted Tacomas, 4Runners and Prerunners from the late 1990s to early 2000s.

How do these arms fix handling after lifting a Toyota?

When you raise ride height, camber and caster angles shift and factory fixed arms can put stress on steering and suspension components. The KSP PERFORMANCE adjustable arms let you return steering geometry to safer ranges, improving tire contact and steering feel.

• Adjustable length corrects camber and caster changes from a 2–4" lift.
• Stiffer, thicker steel tubing resists bending and maintains alignment under load.
• Flexible, greasable ball joint reduces binding and allows flushing of contaminants.

What materials and processes make these arms reliable?

These control arms use high-strength alloy components and manufacturing steps focused on longevity. CNC machining ensures consistent fitment, while heat-treated ball pins and powder coating increase fatigue life and corrosion resistance.

• High-frequency heat-treated alloy steel ball pin for improved wear resistance.
• Thickened cold-drawn steel tube for increased rigidity and chassis correction.
• Powder-coated finish to defend against rust and environmental damage.

How is maintenance handled and what should I be careful about?

The arms feature a greasable socket and a pre-installed dust boot to keep contaminants out and extend service intervals. Follow the manufacturer notes on zerk fittings and avoid over-torquing to prevent damage during regular servicing.

• Pre-installed dust boots protect the ball joint from dirt and debris.
• Greasable socket allows fresh lubricant to push out contaminants and reduce corrosion.
• Do not overtighten zerk fittings; new ball joints generally require no grease for the first year.

Will these arms fit my vehicle and what’s included in support?

The arms are designed for specific Toyota model years and drive configurations; confirming fitment before purchase avoids installation issues. KSP PERFORMANCE backs the product with return and replacement coverage for peace of mind.

• Fitment list: 1996–2003 Toyota Tacoma 4x4, 1996–2004 Toyota Prerunner 4x2, 1995–2002 Toyota 4Runner N180 4x4.
• 30-day refund and 12-month free replacement policy from KSP PERFORMANCE.
• Pre-installed hex hole on the ball pin speeds installation and adjustment.

Who is this for: Off-road enthusiasts and owners who installed a 2–4" lift on supported Toyota Tacomas, 4Runners or Prerunners and need stronger, adjustable upper control arms to restore proper alignment and improve long-term component life. These arms suit anyone seeking a serviceable, durable aftermarket replacement that simplifies alignment correction and reduces suspension-related wear after lifting their vehicle.
