H&R rear sway bar for 2004–2009 Mazda Mazda3 (BK) is a 26mm non‑adjustable anti‑roll bar intended for vehicles with a factory sway bar only; it increases roll stiffness to reduce body roll and improve cornering stability while keeping ride comfort. The upgraded diameter and one‑piece forged ends produce a firmer, more responsive feel. H&R kits commonly include Poly/Teflon bushings that prevent squeaks and require no lubrication.
