Bilstein 25-332315 B8 8100 Black Hawk 3-Way Rear Left Shock 22-26 Toyota Tundra

Vehicle Fitment

• 2022-2026 Toyota Tundra (SR, SR5, Limited, Platinum, 1794 Edition, TRD Sport, TRD Off-Road, TRD Pro, Capstone - 4WD and RWD, Double Cab and CrewMax)

Fitment Notes

• Rear position only - Left (Driver) side
• Does NOT fit Toyota Tundra equipped with the Advance Package rear air suspension (available on Platinum, 1794 Edition, and Capstone trims with the Advance Package)
• Fits both 4WD and RWD (2WD) configurations
• Compatible with both gas (3.5L Twin-Turbo V6) and iForce MAX hybrid powertrains
• Sold individually - pair with Bilstein 25-352016 (Rear Right / Passenger Side) for a complete rear axle upgrade
• When lifting 2 inches or more at the front, ensure RED or SILVER OEM CV axles are installed - BLACK CV axles risk dislodging during full droop
• When paired with the matching B8 8112 Black Hawk front coilovers, an aftermarket upper control arm (UCA) is required to avoid coil contact during full droop
• Factory shock mounting bolts are reused for installation; all necessary washers, bushings, and nuts included
• Optional billet aluminum reservoir clamp available separately for a cleaner installation appearance

Features

• Bilstein B8 8100 Black Hawk Series - the highest-specification direct-fit rear shock available for the 3rd generation Toyota Tundra, featuring Bilstein's exclusive ZoneControl® position-sensitive damping technology
• ZoneControl® triple-stage valving delivers three distinct compression damping zones and two rebound zones that automatically adapt based on shaft position - providing a plush ride over small bumps and maximum bottom-out control at full compression
• 3-way external damping adjustment with click adjuster knobs for independent high-speed compression, low-speed compression, and internal hydraulic bump stop (JCO) control - allowing precise on-the-fly tuning without removing the shock
• Internal hydraulic bump stop (JCO) virtually eliminates harsh bottoming out on severe terrain, delivering a dramatically smoother experience when hitting large impacts at speed
• Large 60mm (2.65 in OD) hard anodized aluminum shock body provides substantially higher oil volume than standard steel-bodied shocks, improving heat dissipation and long-term damping consistency
• Unique finned remote reservoir design dramatically increases oil capacity and surface area for superior heat rejection during extended high-intensity off-road use
• Monotube design with velocity-sensitive digressive valving ensures consistent, fade-free performance across all driving conditions - from daily highway commuting to aggressive trail use
• Constructed from aerospace-quality billet components throughout for unmatched precision and durability
• Direct bolt-on fitment using factory mounting locations - no drilling, cutting, or welding required
• 2-Year Limited Manufacturer Warranty

Product Description

The Bilstein 25-332315 B8 8100 Black Hawk Rear Left Shock Absorber is the most advanced direct-fit rear shock available for the 2022-2026 Toyota Tundra, delivering race-derived ZoneControl® position-sensitive damping, 3-way external adjustability, and a finned remote reservoir in a complete bolt-on package. Designed as the rear companion to the B8 8112 Black Hawk front coilovers, this shock transforms the 3rd generation Tundra's suspension from a capable but conventional setup into a precision-tuned performance system that excels equally on paved roads and demanding off-road terrain. It fits all 4WD and RWD Tundra configurations from 2022 through 2026, including Double Cab and CrewMax body styles, across all trim levels - with the sole exception of vehicles equipped with the Advance Package rear air suspension found on select Platinum, 1794 Edition, and Capstone configurations.

ZoneControl® is Bilstein's most sophisticated position-sensitive damping technology, using a triple-stage compression valve system and dual-stage rebound system that automatically adjust damping force based on where the shock is in its stroke. This means the shock is intentionally soft and compliant over small road imperfections, progressively stiffer through mid-stroke for body motion control, and extremely firm at the end of travel to resist bottoming out - all happening seamlessly and automatically without any manual adjustment. Stacked on top of this passive intelligence are three external click adjusters: high-speed compression, low-speed compression, and an internal hydraulic bump stop (JCO). These allow the driver to fine-tune the shock's character from the outside with simple click adjustments, accommodating variations in load, tire size, and terrain with no tools required. The 60mm hard anodized aluminum body, combined with a unique finned remote reservoir, provides exceptional oil volume and heat dissipation - the two primary performance factors that separate elite off-road shocks from conventional upgrades.

Installation is straightforward using factory mounting locations and the existing factory shock mounting hardware. The included reservoir mounting kit provides all necessary washers, bushings, and hardware for a complete install. This shock is sold as a single left (driver) side unit - pair it with Bilstein 25-352016 to complete the rear axle. When paired with the matching B8 8112 Black Hawk front coilovers for a full system upgrade, an aftermarket upper control arm is required to prevent coil contact during full droop, and Tundras being lifted 2 inches or more should confirm the presence of red or silver CV axles to avoid dislodging at full extension. Bilstein backs the 25-332315 with a 2-Year Limited Warranty.
