Lower Spring Plate C/O LH

The Lower Spring Plate C/O LH from AFCO Racing Products is a precision suspension component engineered for high-performance vehicles requiring adjustable spring rates and geometry control. This left-hand assembly serves as the foundation for fine-tuning ride height, spring preload, and load distribution—critical parameters for autocross competitors, road racers, and enthusiasts building purpose-built chassis. The lower spring plate directly influences how your suspension transfers weight under acceleration, braking, and cornering, making it essential for anyone serious about suspension geometry optimization.

Constructed for durability and precision fit, the Lower Spring Plate C/O LH weighs 2.42 lbs and measures 5.9 x 2.3 x 6.25 inches, making it compact enough for tight suspension bays while maintaining structural rigidity under load. AFCO's racing-grade manufacturing ensures consistent seat surfaces for coilover springs, eliminating geometry drift and spring binding that plague inferior plates. The left-hand configuration is essential for proper suspension symmetry—mixing left and right plates compromises load transfer characteristics and handling balance, so correct side selection is non-negotiable for track performance.

This component is ideal for racers upgrading to adjustable coilover systems, builders converting factory suspensions to independent geometry setups, or competitors requiring repeatable spring preload adjustment between sessions. Installation requires suspension disassembly and proper spring compression equipment—this is not a bolt-on modification. Verify your vehicle's suspension type and coilover diameter before purchase, as spring plates are application-specific and must match your platform's control arm geometry and available clearance. AFCO's reputation for precision makes this plate a trusted choice among serious performance shops and dedicated motorsports enthusiasts.
