About the B8 6112 Series

Bilstein B8 6112 suspension kits are part of the B8 6112 product line, which focuses on leveling and front-end ride-height correction for trucks and SUVs. The series combines a monotube shock design with matched coil springs and adjustable spring perch positions to help tailor stance and suspension travel to the vehicle application. Part number 47-309975 follows that formula for Toyota Tacoma, Toyota 4Runner, Toyota FJ Cruiser, and Lexus GX470 front suspension setups.

What This Suspension Kit Helps Address

• Front-end rake on Tacoma, 4Runner, FJ Cruiser, and GX470 applications
• Limited clearance for larger tires
• Reduced suspension travel from worn or undersized front components
• Inconsistent damping control on mixed street and trail use
• Need for a direct-fit front leveling solution with adjustable ride height

Installation Notes

Verify exact vehicle year, trim, and suspension configuration before ordering. The 2003-2009 Toyota 4Runner fitment is for vehicles without X-REAS suspension, and the 2003-2009 Lexus GX470 application requires Toyota Upper Shock Mount Assy 48609-60100. This front suspension kit uses a snap-ring grooved body with a spring seat included, and the final lift height depends on the vehicle application and perch position selected.

This part cross-references Monroe Shocks & Struts 58630 for the same application.

Quality Assurance

Bilstein B8 6112 components use a monotube shock design with a 60mm piston and zinc-plated damper finish for consistent construction across the series. Part number 47-309975 is engineered as a direct-fit suspension kit for the listed Toyota and Lexus applications.
