The Cusco 19mm rear sway bar for Lexus IS250 and IS350 is a direct-fit upgrade that helps control lateral weight transfer and reduce body roll. At 19mm, it increases rear roll stiffness to complement front anti-roll rates and refine mid-corner balance. This rear stabilizer is intended as a bolt-on handling improvement for the listed Lexus IS models without extensive suspension modification.
