Product Description

The Whiteline BSF33Z is a 22mm heavy duty blade adjustable front sway bar engineered for the 2001-2007 Subaru Impreza WRX/STI (GD/GG) and 2004-2008 Forester XT (SG) turbo platforms. The blade-style adjustable design provides two stiffness settings by repositioning the end link mounting point along the flattened lever arm, allowing drivers to fine-tune front roll stiffness to suit their driving style or conditions without replacing the bar. Constructed from solid steel with forged alloy ends, this bar delivers consistent roll resistance and maximum durability at the critical end link connection point. The protective Silver Sparkle II powder coat finish provides long-term corrosion resistance in harsh conditions. Each bar ships with Whiteline's latest-generation synthetic elastomer polyurethane bushings featuring internal bore knurling and grease retention lips that maintain lubrication over the life of the bushing, eliminating the squeaks and binding common with cheaper polyurethane designs. Installation is a direct bolt-on using OEM mounting points with no drilling or modification required. Whiteline recommends pairing this front bar with a matching rear sway bar -- BSR35XZ for Forester or BSR36Z/BSR36XZ for Impreza/WRX -- to achieve balanced front-to-rear roll distribution and eliminate factory understeer bias.
