H&R 70878 Sport Sway Bar Kit 28mm Adjustable 2-Hole Front

The H&R 70878 Sport Sway Bar Kit is a 28mm, 2-hole adjustable front sway bar engineered to reduce body roll, increase lateral stiffness, and sharpen overall handling performance — all without altering ride height or sacrificing everyday ride comfort.

H&R sway bars are cold-formed using proprietary bending machines designed in-house, then shot-peened and heat-treated for maximum durability and dimensional accuracy. The bar is fabricated from 50CrV4 spring steel, a high-tensile alloy that delivers superior strength and resilience compared to standard sway bar materials.

Key Features:

• 28mm bar diameter for increased roll stiffness over stock
• 2-hole adjustable design allows tuning of understeer and oversteer characteristics to match driving preference
• Precision forged bar ends with smooth, machined-like finish for consistent, reliable adjustability
• Bar is shot-peened and heat-treated for enhanced fatigue resistance and long service life
• Constructed from 50CrV4 spring steel — stronger and more resilient than conventional sway bar materials
• Includes H&R exclusive urethane/Teflon (PTFE) composite bushings — permanently lubricated, squeak-free, and maintenance-free
• Sold as a complete kit — no separate bushing purchase required

The included H&R proprietary bushings feature a urethane/PTFE composite construction that eliminates squeaks and requires zero lubrication, making installation truly bolt-on with no ongoing maintenance. Pairs perfectly with H&R coilovers, sport springs, and cup kits for a fully optimized suspension setup.
