IFS Mustang II Suspension and Brake Kit W/Wilwood Calipers

This comprehensive Mustang II front suspension and brake hardware kit features a collection of parts tailored for optimal fitment, performance, and durability. The package includes crush washers, and rubber brake hoses designed for 7/16"-20 Wilwood D154 calipers. It also provides a complete bearing and seal kit for Mustang II/Pinto rotors, and 11" vented rotors with a 5 on 4.75" bolt pattern designed for GM metric calipers. Additional components include dust caps, brake hose retaining tabs, and gas-charged front shocks with OEM geometry.

The steering and suspension system is fully supported with forged stock-height spindles, upper and lower control arms (complete with polyurethane bushings and ball joints), tie rod nuts, outer tie rod ends, and mounting hardware. Also included are heavy-duty strut rods, strut rod bushings, and brackets for a secure and compliant ride. The steering rack options include both new manual and T-Bird-style power racks (not remanufactured), adaptable to most aftermarket Mustang II crossmembers with necessary bolt kits and spacers.

The brake system is rounded out with GM metric caliper brackets, soft street pads, and D154 2-piston calipers in black or red. For proper ride height and handling, the kit includes 13.5" coil springs in a variety of rates to suit your front-end weight. Whether you're building a street rod, kit car, or classic muscle car, this kit ensures all necessary parts are included for a reliable and upgrade-ready suspension and brake setup.
