Maximum Motorsports Hydroboost Conversion Brake Line Kit

Take the guesswork out of your 1980-1986 Mustang's 99-04 Hydroboost conversion with ABS/traction control with this Maximum Motorsports hydroboost brake line kit! Designed to complete your hydroboost swap when installing a 1999-2004 ABS/traction control master cylinder in your 80-86 Mustang GT or 5.0 LX.

Maximum Motorsports Knows Fox Body Mustangs!

This kit results from careful design and manufacturing to ensure an easy installation. Even so, installation can still be challenging, as the production tolerances of Fox Mustangs are notoriously sloppy. If you’re into Fox bodies, you probably already know about this drawback in your favorite Mustang. When designing the hydroboost conversion kit, Maximum Motorsports found significant tolerances that affected fitment. This discovery led to our engineers designing unique brake hard lines to make adjustments and alignment during installation as easy (and precise) as possible.
