Fitment Notes

• 6th-generation Toyota 4Runner (2025+) only - not compatible with 5th-generation 4Runner (2010-2024).
• Note for 4Runner: The TRD Pro and Trailhunter are equipped from the factory with more advanced Bilstein OEM suspension systems (remote reservoir and ESCV shocks) - the B8 6100 is best suited for SR5, TRD Off-Road, Limited, and Platinum trims seeking a lifted and upgraded aftermarket rear shock.
• 4WD models.
• Provides 0-1.75 inches of rear lift over stock height using OE factory coil springs - no spring replacement required.
• Rear position only, left or right - sold as a single shock absorber. Order 2 for a complete rear axle replacement.
• Boot included. Factory shock mounting hardware is reused for installation.
• Companion front coilover kit: Bilstein 47-347472 (B8 6112, 0-3" front lift).

Features

• Bilstein B8 6100 - Bilstein's dedicated off-road performance shock series, drawing from three decades of off-road racing experience. A substantial upgrade over the factory rear shocks on SR5, TRD Off-Road, Limited, and Platinum 4Runner trims, delivering significantly improved damping control, heat resistance, and off-road capability.
• 60mm digressive piston in a 2.65" OD monotube body maximizes heat dissipation and prevents oil aeration and fade - maintaining consistent damping under sustained off-road use and heavy loads where the 5100 series and factory shocks degrade.
• Self-adjusting deflective disc valving with independent rebound and compression tuning delivers precise damping response across all terrain.
• Factory-rebuildable construction for long-term serviceability.
• Provides 0-1.75 inches of rear lift using factory coil springs - no spring purchase required.
• Boot included for rod protection.
• Zinc-plated finish for corrosion resistance in harsh environments.

Product Description

The Bilstein 24-347440 is a B8 6100 rear shock absorber for the 2025-2026 Toyota 4Runner (6th generation, SR5 / TRD Off-Road / Limited / Platinum - 4WD) and 2024-2026 Toyota Land Cruiser, providing up to 1.75 inches of rear lift using the factory coil springs. The B8 6100 is Bilstein's off-road performance line, developed from decades of desert and off-road racing experience. It sits above the B8 5100 in Bilstein's lineup, featuring a larger 60mm digressive piston in a 2.65" OD monotube body for substantially higher heat dissipation, damping consistency, and fade resistance under sustained aggressive use.

For sixth-generation 4Runner owners on SR5, TRD Off-Road, Limited, or Platinum trims who prioritize off-road performance or are running larger aftermarket tires, the 24-347440 delivers the kind of rear damping control and durability that the factory shocks cannot match across the long haul. The TRD Pro and Trailhunter use more advanced Bilstein remote reservoir and ESCV OEM setups from the factory and are not the primary target for this aftermarket application. Factory-rebuildable for long-term serviceability. Pair with the front Bilstein 47-347472 B8 6112 coilover kit for a complete four-corner performance upgrade. Sold individually - order two for a complete rear axle replacement. Backed by Bilstein's Limited Lifetime Warranty against manufacturer defects.
