GM LH Metric Caliper Oversized

The GM LH Metric Caliper Oversized from AFCO Racing Products is engineered for serious performance brake upgrades on General Motors platforms requiring larger swept area and improved heat dissipation. This left-hand metric caliper addresses the demands of high-performance street and track builds where factory brake systems fall short, delivering the stopping power necessary for upgraded powerplants, suspension geometry changes, and aggressive driving applications. Whether you're building a restomod, drag platform, or road course competitor, an oversized caliper setup is fundamental to balancing power delivery with confidence-inspiring braking performance.

AFCO's oversized metric caliper design increases pad area compared to OEM specifications, which directly reduces brake fade under sustained or repeated high-load stops by spreading thermal stress across greater friction material and rotor contact zones. The metric mounting pattern ensures compatibility with GM-specific brake hardware and wheel clearance boundaries, while the oversized bore and piston configuration maintains progressive, linear pressure response across the entire pedal stroke. At 7.3 lbs per unit, the caliper's casting and internal geometry optimize heat flow away from fluid passages, critical for maintaining consistent friction coefficients during extended driving sessions or competition use.

Street performance enthusiasts and dedicated track builders benefit most from this component when paired with braided steel brake lines, high-temperature fluid, and premium friction pads rated for extended use. This left-hand unit installs on the driver-side front or rear position depending on your brake kit configuration and vehicle platform—verify your specific GM model's caliper mounting orientation and rotor diameter before purchase. Installation requires removal of wheels and brake assembly components; a professional installation is recommended if you lack mechanical experience with hydraulic brake systems.
