Peak Suspension Tubular Upper Control Arms For 4Runner (2025-Current)
DESCRIPTION
When lifting your Toyota 4Runner, the factory upper control arms are one of the first components to fail. Stock arms suffer from poor geometry, reduced strength, and over-articulation that puts unnecessary stress on ball joints and bushings. Peak Suspension engineered a solution designed to deliver correct geometry, maximum strength, and maintenance-free performance for serious off-road use.
Optimized Geometry for Lifted 4Runners
Our tubular chromoly upper control arms are built with increased caster and re-positioned pivot angles to restore proper alignment and suspension travel after a lift. This correction improves straight-line stability, enhances cornering, and ensures your 4Runner handles predictably both on and off the trail.
High-Strength Uniball Design
Weak OE ball joints are replaced with 1” stainless steel ProBearing uniballs, offering unmatched articulation, steering precision, and durability under heavy loads. This upgrade ensures your 4Runner can tackle rough terrain, technical rock crawling, or high-speed desert runs with confidence.
Dual Durometer Bushing Technology
At the inner pivots, we’ve incorporated our latest dual durometer bushing system. Featuring a bonded rubber outer layer with a composite core and inner sleeve, this advanced design:
-
Absorbs vibration and trail chatter for a smoother ride
-
Eliminates noise, squeaks, and harsh feedback
-
Provides a quiet, maintenance-free solution – no greasing required
