UMI Performance 3031-B Tubular Front Lower A-Arms for 1978-2004 GM G-Body, F-Body, and S10/S15

Fits select 1978-2004 Buick, Chevrolet, GMC, Oldsmobile, and Pontiac vehicles, including G-Body (Regal, Monte Carlo, Cutlass, El Camino), F-Body (Camaro, Firebird), and S10/S15/Sonoma platforms.

UMI Performance tubular lower A-arms (Part #3031-B) replace flex-prone factory stamped steel arms with a rigid, high-performance design. Fabricated from USA-sourced DOM tubing, these arms feature CNC notched tube ends and TIG-welded joints for precise fitment and structural integrity. The revised geometry improves the ball joint angle for lowered vehicles and provides increased tire clearance for wider wheel and tire combinations.

These arms are shipped fully assembled and ready to bolt into factory mounting points. They are designed for versatility, maintaining compatibility with factory springs, aftermarket lowering springs, and most coilover conversion kits without requiring modifications. For maximum chassis control and handling performance, these are best paired with UMI upper A-arms.
