PROs Tuning is proud to offer our in-house designed and manufactured Hydroboost adapter kit. This allows you to utilize a GM Hydroboost (hydraulically-assisted brake booster) instead of your factory vacuum-assisted brake booster. This offers the benefits of:

• Increased brake pressure (less pedal effort)
• Consistent performance under boost or with a bigger cam
• OEM reliability with off-the-shelf parts

This kit comes with a raw machined adapter bracket and a brand new Bosch hydroboost. Additional options include a Wilwood master cylinder, hydraulic line kit, anodization, or custom engraving.

Please note - specific for GMT400/OBS applications, please measure firewall to center of brake pedal pin it will be 7 3/8in if it is not please let us know and we can make it the length you need

ALL KITS ARE MADE TO ORDER
