Product Description

The Wilwood 140-11389-D Dynapro Low-Profile 11" Rear Parking Brake Kit is a versatile performance upgrade designed around the Big Ford New Style rear axle flange with approximately 2.50" offset. It features forged four-piston Dynapro calipers and high-capacity drilled & slotted rotors with internal parking brake shoe systems that deliver both strong braking and reliable park-holding power without bulky external hardware. Forged aluminum construction with a black powder-coat finish enhances durability and corrosion resistance while reducing unsprung weight versus older cast designs.

This kit is ideal for custom muscle cars and street/strip builds where rear braking performance and parking brake functionality are desired together. The low-profile layout helps clear 14" and larger wheels in many applications, though wheel clearance should always be confirmed on your specific setup before installation. Brake lines are not included, so a custom or Wilwood brake hose kit is recommended for complete installation.
