MOAB Upgrade For HydroBoost Left Side Drop SKU: 2985

MOAB Upgrade for Hydroboost Power Brakes | Left Side Drop | 66–77 Bronco

Upgrade your hydroboost braking system to the trusted WILD HORSES MOAB system with this Left Side Drop MOAB Hydroboost Upgrade Kit—engineered for clean installation, rock-solid performance, and on-the-fly brake tuning. Built for 1966–77 Ford Broncos, this kit replaces outdated or generic setups with premium Wilwood components, braided stainless lines, and the proven layout WILD HORSES has developed through decades of Bronco brake system expertise.

At the heart of the system is a lightweight Wilwood aluminum master cylinder, paired with our MOAB adjustable proportioning valve—allowing precise tuning of front/rear brake bias via a convenient knob mounted right on the valve. Stainless hard lines connect the valve cleanly to the master cylinder, while braided stainless flex hoses route to the frame-top factory brake lines through a bolt-in stainless hose bracket.

For 1967–75 Broncos, the stainless hoses connect directly to the factory lines with no adapters required. If you’re working on a 1976–77 model, select your year from the dropdown—additional lines are included for a proper fit.
