Bilstein 25-288162 B8 8100 Bypass Rear Right Shock 2007-2014 Toyota FJ Cruiser

Vehicle Fitment

• 2007-2014 Toyota FJ Cruiser Base (4WD, 4.0L V6, 0-2" Rear Lift)
• 2007 Toyota FJ Cruiser TRD Special Edition (4WD, 4.0L V6, 0-2" Rear Lift)
• 2008 Toyota FJ Cruiser Trail Teams Special Edition (4WD, 4.0L V6, 0-2" Rear Lift)

Fitment Notes

• Position: Rear Right (Passenger Side) - sold individually. A matching rear left bypass shock (25-288155) is required for a complete rear axle installation.
• Fits vehicles at factory ride height or with up to 2" of rear lift.
• All Toyota FJ Cruiser models sold in the US (2007-2014) are 4WD - this shock fits the full production run.
• Remote reservoir chassis mount is included - uses a bolt-on aluminum anodized bracket for a clean, no-fabrication installation.

Features

• Bilstein B8 8100 (Bypass) series - motorsport-derived dual-tube externally adjustable bypass design purpose-built for serious off-road performance on light trucks and SUVs.
• "Incremental Flow" bypass adjusters allow finite, independent tuning of both rebound and compression damping, enabling precise suspension setup for any terrain, trail condition, or load.
• Position-sensitive damping: bypass ports are strategically placed along the shock body to deliver softer damping in mid-stroke for maximum wheel travel and compliance, automatically stiffening near full compression for outstanding bottom-out control.
• Bottom-port remote reservoir hose exit delivers increased compression control during the full suspension cycle, while the external reservoir dramatically improves heat dissipation for sustained fade-free performance on long off-road runs.
• 60mm large-bore hard-anodized aluminum piston provides a greater range of damping control and exceptional long-term durability under heavy off-road abuse.
• 18mm piston rod provides maximum tensile strength and reduces internal gas force ramp-up for a smoother, more predictable ride feel.
• Billet rod end with vulcanized mounts ensures an exact OE-quality bolt-in fit and long-term vibration resistance.
• Made in the USA and German TUV-certified for quality and performance.

Product Description

The Bilstein 25-288162 is a B8 8100 (Bypass) rear right shock absorber engineered specifically for the 2007-2014 Toyota FJ Cruiser 4WD across all trims, supporting factory ride height and up to 2" of rear lift. This is a motorsport-derived, externally adjustable bypass damper - not a traditional monotube or twin-tube shock - bringing race-level tunability to a direct-fit bolt-on package. The dual-tube bypass design with Incremental Flow adjusters allows for independent tuning of rebound and compression damping, enabling drivers to precisely configure their suspension for the terrain at hand. Position-sensitive bypass ports are calibrated to provide compliant, supple damping through mid-stroke for better wheel articulation and trail feel, while automatically delivering firm bottom-out control as the suspension approaches full compression - the same position-sensitive behavior found in purpose-built desert race vehicles.

The remote reservoir significantly increases oil volume capacity and heat dissipation far beyond what a traditional shock can manage, preventing fade on sustained off-road runs. The included bolt-on aluminum anodized chassis mount keeps the reservoir installation clean and professional without custom fabrication. This is the rear right (passenger side) shock; the matching rear left is 25-288155. Both units are required for a complete rear axle installation. Made in the USA, TUV-certified, and backed by Bilstein's 2-Year Limited Warranty.
