ICON Vehicle Dynamics Billet Upper Control Arm with Delta Joint for 1996-2004 Toyota Tacoma and 1996-2002 Toyota 4Runner

The ICON Vehicle Dynamics Billet Upper Control Arm with Delta Joint Kit is a direct bolt-in suspension upgrade for 1996–2004 Toyota Tacoma and 1996–2002 Toyota 4Runner, built from CNC machined 6061 billet aluminum and fitted with ICON's patented Delta Joint (U.S. Pat. 10,731,700) in place of the factory upper control arm. One kit covers both the Tacoma and 4Runner applications listed above.

Billet Aluminum Built to Last Off-Road

The control arm body is CNC machined from 6061 billet aluminum and finished in a matte anodization process. That combination resists corrosion without adding unnecessary weight, so the arm holds up to repeated exposure to mud, water, and road salt that would degrade a painted steel arm over time. Machined adjuster sleeves are integrated into the design, allowing caster and camber to be set on the vehicle without removing the arm. This is a practical advantage when dialing in alignment after a lift or after trail use changes the geometry.

Delta Joint: Ball Joint Durability, Uniball Articulation

The patented Delta Joint replaces the uniball found on many aftermarket control arms. A standard uniball allows high articulation with minimal bind, but its open metal-on-metal interface is vulnerable to contamination in daily-driven or frequently off-road vehicles. The Delta Joint addresses that directly: a zinc plated housing provides a first layer of corrosion resistance, a tough grease seal keeps debris out of the joint internals, and an O-ring sealed cover cap adds a second barrier. The greaseable, metal-on-metal construction extends service life while allowing noise-free operation. The result is a joint that articulates at greater angles than a conventional ball joint while remaining more weather-resistant than a standard uniball.

Increased Droop Travel When Paired with Extended Travel Coilovers

When used alongside ICON extended travel coilovers, the billet upper control arm geometry allows for increased droop travel compared to the factory arm. Greater droop keeps tires in contact with uneven terrain longer, improving traction and reducing the harshness transferred to the chassis on rough surfaces. The PTFE-lined 3/4" FK rod ends contribute to smooth, consistent articulation throughout the suspension's range of motion.

Specifications

Who This Is For and Isn't

This kit suits owners of 1996–2004 Toyota Tacoma (4WD) and 1996–2002 Toyota 4Runner who are lifting their vehicle and want a bolt-in upper control arm that restores or improves alignment geometry, increases droop travel when paired with extended travel coilovers, and provides a weather-resistant high-angle joint for both daily driving and off-road use.

This kit does not fit 2WD Toyota Tacoma models equipped with 5 lug wheel studs. It is not a complete suspension system and does not include coilovers, lower control arms, or alignment tools.

Common Questions

Does this upper control arm fit a 2WD Toyota Tacoma?

The ICON billet upper control arm kit (SKU 58500DJ) does not fit 2WD Toyota Tacoma models with 5 lug wheel studs. It is confirmed to fit 1996–2004 Toyota Tacoma 4WD and 1996–2002 Toyota 4Runner.

Will OEM wheels and tires still clear this control arm?

Yes. The ICON billet upper control arm kit is compatible with OEM wheels and tires on the applicable Tacoma and 4Runner fitments. Aftermarket wheels up to 20x9" with 5" backspace also fit the applicable Tacoma and 4Runner fitments with this control arm installed.

What is the Delta Joint and how does it differ from a uniball?

The Delta Joint (U.S. Pat. 10,731,700) is ICON's patented high-angle ball joint. Unlike a standard uniball, it uses a zinc plated housing, a grease seal, and an O-ring sealed cover cap to keep contaminants out of the joint internals, making it more suitable for daily-driven vehicles exposed to the elements while still providing greater articulation than a conventional ball joint.

Can caster and camber be adjusted without removing the arm?

Yes. The ICON billet upper control arm includes machined adjuster sleeves that allow caster and camber to be tuned on the vehicle, without removing the arm. This makes it practical to fine-tune alignment after installation or after suspension changes.

Does this kit increase wheel travel?

The ICON billet upper control arm can provide increased droop travel when paired with ICON extended travel coilovers. The arm alone does not guarantee additional travel; the gain depends on the coilover system used alongside it.
