Heritage Series Front Sway Bar Bushing - 21mm

Product Details

Deflection Recovery: Heritage Series 21.5mm Front Sway Bar Bushings

Dynamic compliance at the anti-roll bar mount directly compromises cornering efficiency and front-axle bite. When carving corners, soft or degraded rubber front sway bar bushings flex heavily under load, delaying the translation of the bar rate and allowing uncommanded body roll. The Powerflex PFF5-4602-21H Bushing Set is a technical-grade mechanical overhaul designed to lock down factory 21.5mm front anti-roll bars.

Part of Powerflex's Heritage Collection, these bushings utilize an advanced polyurethane formulation that yields an optimized road and track-day durometer curve while remaining entirely free of structural deflection. This ensures immediate steering translation and reduced lateral weight transfer under load. Finished in an ultra-discreet dark grey finish, they integrate flawlessly into a factory-original undercarriage layout—making them an essential upgrade for purists seeking maximum handling stability.

Technical Features:

• 21.5mm Internal Diameter: Precision molded for exact fitment on factory-spec 21.5mm front anti-roll bars.

• Deflection Resistance: Stabilizes the bar pivot points to completely eliminate lag during hard cornering inputs.

• Advanced Polyurethane Engineering: Immune to dry-rotting and thermal wear, carrying a comprehensive lifetime performance warranty.

• Low-Stiction Inner Bore: Engineered with knurled internal grease reservoirs to retain lubrication and guarantee silent, smooth operation.
