When lifting your Silverado or Sierra 1500 by 2"–4", factory upper control arms can't maintain proper alignment and often lead to negative camber and poor handling. The SuperPro TRC6655 fixed-offset arm set restores geometry, adding +4.0° caster and correcting camber to -0.5° (measured at 3" lift), using the stock lower arms. With OE+ durability from hardened ball joints and maintenance-free SuperPro bushings, the TRC6655 delivers serious chassis control for both trail and pavement driving.

Key Features:

• Fixed-offset UCA set tailored for 3" lift: delivers +4.0° caster and –0.5° camber with OEM lower arms

• Pre-installed SuperPro polyurethane bushings—no pressing required

• Heavy-duty, high-articulation ball joints for rugged durability
