H&R 72878-5 Sport Sway Bar Kit 28mm Front / 20mm Rear with Bushings

The H&R 72878-5 Sport Sway Bar Kit delivers a complete front and rear anti-roll bar upgrade engineered for drivers who demand sharper handling and reduced body roll without sacrificing everyday ride comfort. This kit includes a 28mm front sway bar and a 20mm rear sway bar, along with all required mounting bushings — everything needed for a complete installation.

H&R sway bars are cold-formed and heat-treated from a proprietary 50CrV4 high-tensile steel alloy, the same material used in premium spring manufacturing. Each bar is additionally shot-peened for increased surface hardness and fatigue resistance, then finished with a durable powder coat for long-lasting corrosion protection. All bars are manufactured on specialized H&R machines to ensure precise fitment and consistent performance in every application.

Key Features:

• 28mm front bar — 2-hole adjustable forged ends for fine-tuning roll stiffness
• 20mm rear bar — non-adjustable, optimized for balanced handling response
• Machined-like forged ends allow stiffness adjustability on applicable positions
• Constructed from 50CrV4 high-tensile spring steel alloy for maximum durability
• Heat-treated and shot-peened for superior surface hardness and extended service life
• Powder-coated finish for long-term corrosion resistance
• Manufactured in Germany to ISO 9001 and TÜV certification standards

Included Bushings: This kit comes complete with H&R's proprietary sway bar bushings, constructed from a urethane/Teflon composite with a molded-in fabric-like liner. This unique formulation eliminates squeaking and requires no lubrication — no greasing, no maintenance, just install and drive.

The H&R 72878-5 sway bar kit pairs seamlessly with H&R coilovers, sport springs, and cup kits for a fully integrated suspension upgrade.
