Wilwood 140-14422-D Dynapro Lug Mount Front Drag Brake Kit for Dodge

Wilwood's Dynapro Lug Mount (DPL) Front Dynamic Drag Brake Kit (Part No. 140-14422-D) is engineered for serious drag racing applications on Dodge muscle car spindles and struts. Designed for four-wheel disc brake cars weighing up to 2,800 lbs or rear drum brake-equipped cars weighing up to 2,400 lbs, this kit delivers race-proven stopping power with a dramatic reduction in unsprung weight.

Dynamic Lug Mount Rotor System:

The defining feature of this kit is its dynamic rotor mounting system with T-nuts. This lug-drive design allows rotors to move independently of the hubs as they expand and contract through heat cycles, eliminating thermally generated stress at the rotor attachment points. The result is rotors that stay flatter, run truer, and last longer — with more consistent brake response and pedal feel throughout a race event.

Key Features:

• Forged billet DPL four-piston calipers mount directly to the spindle via aluminum bolt-on brackets
• Dynamic rotor mounting adapters with T-nuts reduce thermal distortion and extend rotor service life
• Forged billet five-lug hubs with direct-mount steel rotors for maximum strength and rigidity
• Average weight savings of over 30 lbs compared to stock drum or disc brake assemblies
• Rated for four-wheel disc brake cars up to 2,800 lbs or rear drum brake cars up to 2,400 lbs
• Compact enough to clear popular 15-inch drag racing wheels

What's Included:

• Forged billet DPL four-piston calipers (pair)
• Direct-mount steel rotors
• Forged billet five-lug hubs
• Aluminum caliper mounting brackets
• All new hardware
• Wheel bearings and seals
• Extra-length lug studs

The Wilwood 140-14422-D is a complete bolt-on front drag brake conversion that delivers consistent, fade-resistant stopping power run after run — making it an ideal upgrade for any serious Dodge-based drag racing build.
