UMI Performance 2655-B Corner Max Front Lower A-Arm Set Coilover Camaro Firebird

The UMI Performance 2655-B Corner Max Front Lower A-Arms are a high-performance, direct bolt-in suspension upgrade engineered specifically for 1970–1981 Camaro and Firebird applications. Designed and manufactured 100% in Philipsburg, PA, USA, these arms are built from 1.500" DOM steel tubing and represent a ground-up rethink of the stock-mount A-arm design for maximum front-end performance.

Key Features:

• Constructed from 1.500" USA-made DOM steel tubing for superior strength and reduced weight
• Coilover-only design eliminates the spring bucket for a lightweight, race-focused package
• Premium Howe standard-height ball joints pre-installed for high-quality, reliable articulation
• Lower ball joint relocated forward to increase caster by up to 4 degrees
• When paired with UMI P/N 2656-1, up to 10 degrees of caster can be achieved for the ultimate handling package
• Improved camber curve and roll center height for increased front-end grip
• Delrin bushings provide smooth suspension travel and reduced deflection
• Removable lower mounting system allows spring changes at the track without separating ball joints
• Double-shear coilover mount accepts race-standard ½" rod-end shocks; spacers included for all popular shock models
• Swivel-style double-shear sway bar mounts and hardware compatible with UMI P/N 4035, 4067, and most factory eyelet-style sway bars
• Enhances steering feel and straight-line stability
• Manufactured and race-tested with pride in Philipsburg, PA – USA

Hardware Compatibility:

• Arms include both mounting sleeve sizes to accept either hardware specification
