FDL Pro-Series Front Hub Kits offer complete disc brake upgrade solutions for traditional non-ABS spindle applications on American muscle cars, vintage rods, and heavy weight drag cars. Based on the venerable forged billet Dynalite caliper, these versatile kits are easily optioned to suit the braking requirements and style preferences for a daily driver, serious competition, or the most discriminating show enthusiast. Most kits require no modifications for installation, and provide plenty of clearance inside popular 15†wheels. FDL Pro-Series kits can be used with either manual or power boost master cylinders.
