2024 Toyota 4Runner Upper Control Arms

Upper Control Arms Engineered for 2024 4Runner Lift Kits

The 2024 Toyota 4Runner front suspension shifts geometry when you add a lift kit. Factory upper control arms can't compensate, causing accelerated tire wear and poor handling. If you're working on a similar generation vehicle, an upper control arm for 2023 4Runner relocates the ball joint mounting position to restore caster and camber angles. You get proper alignment, predictable steering response, and even tread wear across all tire contact patches.

Our Gen 4.5 design features DOM tube steel construction with CNC-machined 4140 chromoly ball joint housings. Eight individual grease ports feed EZ Lube Bushings with pressure relief valves. Max 90 Ball Joints deliver 90-degree articulation without binding. Every component is rebuildable. The lifetime structural warranty covers the arm body and welds for as long as you own the vehicle.

Compatible With Factory and Aftermarket Lift Series

JBA upper control arms work with 2 to 4-inch lift configurations on 2024 4Runner models. The adjustable upper control design accommodates varying lift heights without requiring spacers or drop brackets. Install these arms alongside your existing lift kit to correct suspension angles. They're compatible with both coilover and traditional spring setups, including builds that carry heavy front-loaded gear or aftermarket bumpers.

EZ Lube Bushings and Heim Joints Alternative

Most adjustable upper control arms use sealed heim joints or polyurethane bushings. Heim joints wear quickly in dirt and moisture. Polyurethane bushings bind under articulation. JBA's EZ Lube Bushings feature eight grease ports that let you service the pivot points on the trail. Pressure relief valves prevent over-greasing. You extend component life by maintaining lubrication intervals instead of replacing entire assemblies.

Our bushings outperform heim joints in dust, mud, and water crossings. A jungle fleet in Central America runs JBA arms on daily patrol vehicles. After 60,000 miles of unpaved roads and river crossings, the arms required only routine greasing. No replacements. No failures. That's the difference between sealed components and serviceable engineering.

Max 90 Ball Joints for Full Front Suspension Travel

The Max 90 Ball Joint is CNC-machined from 4140 chromoly steel with a 90-degree range of motion. It handles extreme articulation without reaching mechanical limits. When your front suspension compresses over rock ledges or extends into washouts, the ball joint pivots freely. You avoid binding, popping, or premature wear. The joint is rebuildable. When the boot tears or the stud shows play, you replace the internal components without buying a new control arm.

Tubular Steel Arms Built for Offset Load Conditions

JBA uses DOM tubular steel for the arm body. The material resists bending under side loads when you're off-camber or hitting obstacles at speed. We've tested these arms in desert rock crawls, high-speed prerunning, and expedition rigs carrying 300+ pounds of front bumper and winch weight. The steel construction holds alignment under load. The welds don't crack. The lifetime structural warranty backs that claim.

Lower control arms handle compression forces. Upper control arms manage tension and lateral loads during articulation. JBA's design accounts for both. The ball joint housing is welded at multiple points to distribute stress. The bushing pockets are reinforced to prevent elongation. You're not replacing bent arms after a hard trail day.

Do you need upper control arms on your 4Runner? If you're running a 2-inch lift or taller, the answer is yes. Factory arms can't restore proper alignment angles. How much does it cost to replace a control arm on a 4Runner? JBA arms are priced as a long-term investment. You pay once, maintain them with grease, and they last the life of the vehicle. The alternative is replacing sealed components every 30,000 to 50,000 miles.
