PROlift is JRZ’s hydraulic ride-height system. It raises the nose of a lowered car for driveways, aprons, and speed bumps, then lowers itself back down. It changes spring preload only, so the valving and spring rates you specced stay untouched. The documents below cover the front-axle system.

About PROlift
PROlift sits at the spring perch and varies spring preload hydraulically. A small pump feeds a hydraulic adjuster that rides over the damper body, and a control unit drives it to a target height and holds it there on closed-loop feedback. It runs on 12V, is compatible with all RS-line and Motorsport-line dampers, and the front-axle system weighs 5.13 kg (11.3 lb). Above a set speed the car lowers itself back to base automatically.
