The TeraFlex Bronco Adjustable Rear Upper Control Arms feature a factory-style semi-float design with a 3.25" O.D. x 0.375" wall DOM axle tube and Constant Radius Design (CRD) for improved ground clearance. This product includes 35-spline inner and outer axle shafts, heavy-duty bearing caps, and a high-capacity oil reservoir. Designed with an asymmetric layout, it features pre-installed inner axle seals, a ductile cast iron housing, and a heavy-duty ductile iron differential cover.

The arms are finished with a UV-protected triple-stage powder coat and include 1/4"-thick CNC laser-cut axle brackets and pre-installed upper control arm bushings to ensure proper pinion angle for lifted applications. This product is engineered, designed, and built in the USA, also including pre-tapped holes for bump stop extensions and pre-drilled holes for limit straps and lower spring retainers.
