4Runner 2025-2026 Toyota Upper Control Arm Kit (UCA) by Old Man Emu

Old Man Emu UCA0037 Upper Control Arms are engineered to restore proper suspension geometry and steering performance on independent front suspension (IFS) Toyota 4Runners equipped with a suspension lift. Acting as the critical link between the vehicle frame and the knuckle spindle, upper control arms play a key role in maintaining wheel alignment, controlling articulation, and ensuring predictable handling both on and off the road.

When an IFS vehicle is lifted, factory alignment settings can move outside their acceptable range. Old Man Emu Upper Control Arms are designed to bring alignment cams back into spec, allowing for proper caster and camber correction after lifting. The result is smoother, more responsive steering and improved overall drivability. A professional wheel alignment is required after installation, and fender clearance should be verified when running aftermarket wheels and tires. Constructed with a heavy-duty tubular design, these control arms feature forged eyelets and ball joint housings for increased strength and long-term reliability. A free-pivoting, grease-free GIIRO bushing allows smooth suspension movement without maintenance, while the heavy-duty greaseable ball joint includes a protective cap for extended service life.

Designed to handle tougher terrain and increased suspension travel, Old Man Emu Upper Control Arms provide added clearance for larger tires and improved off-road capability. Finished in a premium textured black coating for durability and easy cleaning, these UCAs are built to perform in harsh conditions while delivering precise handling and a refined driving experience.
