Performance Anti-Sway Bars

Buying Guide

Fits Model 3 and Model Y front and rear. You get a 24mm front and 22mm rear bar in adjustable steel, with end-link mounting points common to both cars — though the Y sits higher and heavier, so expect a different feel than the 3 from the same bars. Sold as the front/rear pair, not a single bar.

A medium DIY if you have a jack, stands and the right sockets: drop the wheels, swap the bars at the mounts and set the adjustable end positions, no alignment strictly required for sway bars alone. Before buying, know that stiffer bars cut body roll but firm up the ride and shift handling balance — the adjustable holes let you tune understeer/oversteer, so plan a test-and-adjust afternoon. Check your existing bushings; worn ones will undercut the upgrade.
