Three-Link Rear
To take the vintage Mustang suspension to the max, GPS offers a three-link rear setup that eliminates the factory leaf-springs and their inherent axle hop under hard acceleration and jounce over railroad tracks and bumps. With its super-long torque arm, coilover shocks, and sturdy construction, the GPS three-link provides confidence for attacking corners on the road course or digging in off the line at the drag strip. The $3,500 package comes with a 9-inch rear end housing; just add your 9-inch center section. Urethane isolated trailing arms help to prevent axle wind-up.

The base three-link kit is designed to be a perfect match for the GPS Super Stock GT strut kit. Three-link packages are also available with upgraded shocks to match the Street Avenger, Street Performer, Street Extreme, and Pro Front kits.
