Product Details

Replacement power brake booster. Make sure that your brake system is at optimum performance by installing one of these dual-diaphragm boosters. This is also a great upgrade for older boosters, as it increases your braking pedal pressure and helps you stop sooner. OEM correct for 1983-1991 FSJ's, but will fit earlier years. Note that the dual diaphragm boosters use the later model plastic-reservoir master cylinders.

    Didn’t have the spacer to install against the firewall. Ryan, as usual, was beyond helpful giving me places to look for the part. Without these guys I would never finish my Waggy.
