Product Details

The Wilwood 140-5746-B Forged Dynalite Pro Series Rear Disc Brake Kit delivers a complete, bolt-on rear braking solution engineered for GM 12-bolt rear axles with special (billet) housing ends and a 2.91" axle offset. Designed for performance street, strip, and show applications where individual wheel parking brakes are not required, this kit upgrades stopping power while adding undeniable style.

At the heart of the kit are forged billet Dynalite four-piston calipers finished in black powder coat, delivering exceptional clamping force and consistent fade resistance. Paired with 12.19" vented iron-alloy rotors featuring a two-piece hat-and-rotor assembly, the system provides optimized heat dissipation and balanced braking performance under competition and street conditions alike.

Kit Specifications:

  • Rear axle application: GM 12-Bolt Special End (billet housing ends)
  • Axle offset: 2.91"
  • Fixed bearing: 3.15"
  • Rotor diameter: 12.19" vented disc
  • Caliper type: Forged billet Dynalite, 4-piston, black powder coat finish
  • Minimum wheel diameter: 15"
  • Mount type: Lug mount
  • No parking brake assembly included or required

What's Included:

  • Forged billet Dynalite 4-piston calipers (black powder coat)
  • Two-piece aluminum hat and vented iron-alloy rotor assemblies
  • High-friction Polymatrix brake pads
  • Aluminum caliper mounting brackets
  • Grade 8 mounting hardware
  • Detailed installation instructions

The FDL caliper series supports a full range of optional finishes—including red and polished—for builders who want to match their brake setup to a custom aesthetic. Rotor options are also available in cross-drilled, slotted, and e-coated configurations to suit show car presentation or heavy-duty competition cooling demands.

Installation is straightforward using common hand tools, making this an ideal upgrade for muscle car builds, pro-street machines, and off-road competition vehicles running GM 12-bolt rear ends.

Very easy way to order

Quick and easy

They had the parts I needed at the best price. I needed some questions answered to make sure I was ordering the right parts for a 4 year old car and they were very helpful when I called.

Autoplicity has an abundance of name brand parts at unbeatable prices. Customer service was also great to deal with. Receipt and tracking info was provided promptly.

Autoplicity had fast shipping at a low price compared to other competitors. The price for the item itself was the lowest around so I think I got a good deal or my car. Would buy from again!

Authentic, hard to find item listed for the least expensive price online! Good customer service and fast shipping time!!
