KSP PERFORMANCE Adjustable 2–4" Steel Upper Control Arms for Toyota Tacoma/Hilux/Fortuner – Tubular 1.25" DOM, Sealed Ball Joints

These tubular front upper control arms (UCAs) are built from 1.25" DOM steel with powder-coat protection, high-quality sealed ball joints and polyurethane bushings to resist wear from off-road use, road salt and harsh conditions. They provide an adjustable solution to correct caster and camber after a 2–4" lift, preserve steering geometry and extend joint life with KSP dust covers and Tower-style boots. Each kit includes left and right arms sized for specific Toyota chassis; note fitment exclusions for Tacoma 2WD (2004–2015) except Prerunner models.

How do these UCAs restore alignment after a lift?

Raising a vehicle alters factory caster and camber, often causing uneven tire wear and steering pull. These adjustable arms let you set the upper control arm length to reclaim proper wheel geometry and maintain correct steering axis inclination. Use them with a professional alignment to maximize tire life and handling.

• Adjustable thread sleeves correct camber and caster after 2–4" lifts.
• Fat 1.25" DOM tubing resists flex under load for predictable geometry.
• Polyurethane bushings reduce deflection compared with stock rubber.

What makes the ball joints durable for off-road use?

KSP PERFORMANCE installs heat-treated ball pins and clear-thread construction to resist cracking and fatigue. The ball joints use Tower-style boots and a protective KSP dust cover so sand, mud and water are kept away from critical internals, helping them last through severe environments.

• Sealed Tower boots prevent boot displacement during travel.
• Heat-treated pins and clear threads improve joint longevity.
• KSP dust cover reduces contamination for extended service life.

How do I maintain and install these upper control arms?

Installation replaces the factory upper arm with the tubular UCA and requires basic suspension tools and torque specifications from Toyota. Grease fittings are provided; follow KSP instructions for zerk tightening and grease intervals to avoid damage. A full alignment is recommended after installation and any height change.

• Do not overtighten grease zerk fittings; tighten after greasing.
• New ball joints need no extra grease for the first year under normal service.
• Professional alignment recommended after installation and lifting.

What vehicles do these UCAs fit and what should I check before ordering?

The kit fits Toyota Tacoma (2nd gen 2004–2015 and 3rd gen N300 2015–2023), Tacoma Prerunner 2005–2023, Hilux 7th/8th gen (AN10/20/30 2004–2015; AN120/130 2015–2021) and Fortuner 2004–2021. Verify your model year and drivetrain: these arms do not fit Tacoma 2WD (2004–2015) unless it is a Prerunner. Check wheel offset and shock clearance when running large tires.

• Compatible with 2–4" lifts on listed models; verify exact year and trim.
• Not for 2004–2015 Tacoma 2WD, except Prerunner versions.
• Consider tire and wheel clearance for lifted setups.

Who is this for: These KSP PERFORMANCE upper control arms are designed for off-road enthusiasts, weekend trail rigs and daily drivers that have been lifted 2–4" and need restored steering and suspension geometry. They suit owners who want stronger, serviceable components than stock arms—featuring durable DOM tubing, sealed ball joints and polyurethane bushings—plus a supplier warranty and post-sale support for replacement parts or ball joints.
