1988-98 OBS GM Truck Manual Master Cylinder Kit 20-110

Our Manual Brake Master cylinder kit utilizes a billet firewall mounting plate CNC'd from 6061 Aluminum. This plate is designed to utilize a Strange Engineering Mopar Dual Master Cylinder. This requires you to drill your brake pedal for the master cylinder pushrod Kit includes all hardware necessary, Strange Engineering Mopar Dual Master Cylinder.

Included: 

• 6:1 Pedal Ratio optimized for manual brakes
• Billet Manual Master Cylinder Firewall Plate
• Strange Dual Mopar Master Cylinder
• Hardware for Installation
• Brake Push Rod w/ Heim Joint for attaching to pedal
• Fittings for Master Cylinder

*Note: Slight modification to existing bolt holes on firewall needed to accommodate brake plate. Additionally factory pedal assembly needs to be removed and studs going through firewall to hold factory master cylinder need to be removed from pedal assembly by cutting as bolts will be put in place*

Note: This kit improves the brake pedal ratio for use with manual brakes vs. power brakes.  While sharing the original bolt pattern, this requires you to modify the existing hole where the master cylinder goes through the firewall to accommodate the stronger ratio. 

Note: Due to the difference in pedal travel based off of the required manual master cylinder ratio, brake light switch may require modification to work properly based off of pedal position.
