Wilwood Forged Dynalite Rear Drag Kit Drilled Rotor Big Ford 2.50in Offset
FDL Rear Drag kits are true bolt-on kits available for all popular muscle car rear axles and aftermarket rears built with custom axle ends. Kits in this group are purpose built for sportsman category door cars and others with full functional four-wheel disc brakes. Based on the specific style of housing end and axle offset, mounting kits securely install the four-piston forged Dynalite caliper over 3/8” plate steel rotors that are mounted to the axle with an aluminum hat. Standard kits include solid face rotors, with optional drilled rotor kits available to further reduce driveline weight in classes where every weight advantage is necessary.

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.

Disc Brakes, Rear, Drag Race, Cross-Drilled Rotors, 4-Piston Calipers, Ford, 9 in. Big Bearing, Kit
Having disc brakes up front is a great idea and Wilwood Dynalite rear drag kits make it possible to have them in the rear, too. They're built around Wilwood's forged billet 4-piston calipers, lightweight alloy-steel rotors with machined aluminum mounting hats, and Smart Pad brake pads. This combination produces great stopping power and simultaneously reduces both rotating mass and overall vehicle weight. That lighter overall weight, in turn, can translate into lower ETs. The kits come complete with Grade 8 and aircraft-quality mounting hardware.
