The Core 4×4 upper control arms for the Toyota 4Runner

When you lift your 4Runner, the rake angle can cause your spindle to shift, resulting in a quick loss of caster, even with small lifts. As the factory control arm pivots, it causes a loss of clearance around the coilovers and creates a severe ball joint angle, leading to premature failure.

At CORE, we’ve been hard at work developing our upper control arms to solve these issues. We weld our ball joint cups at an angle to help restore lost caster and provide a more neutral ball joint angle, reducing stress on your joints. We also use greaseable polyurethane bushings with custom-made independent crush sleeves with built-in spacers for ease of installation and improved arm travel. But what sets us apart is our use of ½” plate steel, which allows us to weld our bushings at an offset, providing increased clearance with your coilovers and greater down travel in your suspension.

Our kit includes custom-built crush sleeve spacers and detailed instructions for all truck configurations, whether factory height, leveled, or lifted. You can also check out our channel for an informative installation video.

Design Features:

• 1/2″ Plate steel with welded offset
• Angled ball joint cups
• 90 degree grease fittings for easy access

Two-Stage Powder Coating

Our control arms undergo a two-stage powder coating process. First, a zinc primer base coat is applied for exceptional corrosion resistance, followed by a durable top coat available in 10 color choices to match your vehicle’s style.
