Product Description

The Air Lift 78701 is a bolt-on rear air suspension kit for the 2017-2023 Tesla Model 3 (RWD and AWD) and 2020-2025 Tesla Model Y (AWD). The kit replaces the factory rear coil suspension with double-bellow air springs over monotube dampers, delivering 145mm (5.7") of drop from stock ride height while retaining full daily drivability. Air pressure adjustments allow the rear to be raised for speed bumps and driveways or slammed to the ground for shows -- all without tools.

The monotube dampers feature 30 levels of compression adjustment, spanning a range wide enough for comfortable street use at one end and track-ready stiffness at the other. Adjustable lower perches allow ride height to be set independently of bag pressure, enabling precise wheel-gap tuning without changing the handling balance. All dampers are dyno-matched in pairs before shipping. No modifications are required for installation on any compatible Model 3 or Model Y variant. The factory rear stabilizer bar is retained. Pair with Air Lift 78101 (Model 3 RWD) or 78102 (Model 3 AWD / Model Y) front kit for a complete air suspension setup.
