Compact Tandem Master Cylinder – Mopar 4-Bolt – 1 Inch Bore – Chrome Powder Coat

Compact tandem outlet master cylinder designed specifically for Mopar vehicles using the unique four-bolt firewall mounting pattern found on A-body, B-body, and E-body cars from the 1960s and 1970s. The rectangular mounting flange matches factory Mopar firewall layouts, making this an ideal performance-oriented replacement or upgrade.

This master cylinder features an aluminum body with an integral reservoir and dual hydraulic circuits. The 1.00 inch bore version is suitable for both manual and power-assisted brake systems. The compact design provides excellent clearance while offering modern braking performance and significant weight savings compared to original cast-iron units.

Finished in chrome powder coat for durability and a clean engine bay appearance. This version does not include a pushrod.
