Bilstein B8 6112 Front Suspension Kit with 1.3–3.7 in Lift for 4th-Gen 4Runner (2003–2009)

The B8 6112 Front Suspension Kit is designed for 4Runner owners seeking significantly improved suspension capability without compromising everyday drivability. By combining premium Bilstein dampers with application-specific coil springs, the kit enhances ride quality while providing additional lift for larger tires and improved trail performance.

Snap-ring grooves machined into each shock body allow the aluminum spring seat to be positioned at several ride heights. This provides adjustable front lift from 1.3 to 3.7 inches, allowing owners to tailor vehicle suspension geometry.

Each shock uses a large 2.65-inch body for excellent heat dissipation and fade-resistant performance. The larger shock body also contributes to improved damping consistency over long highway drives and extended off-road use.

60-millimeter pistons are engineered to provide excellent low-speed body control. Combined with vehicle-specific valving, the system delivers confident handling on pavement and exceptional control across rocks, and washboards.

The B8 6112 kit includes custom-matched coil springs specifically engineered to complement the shocks. Billet-aluminum spring seats complete the package, creating a cohesive suspension system designed for balanced performance.
