Bilstein 25-331707 B8 5165 Remote Reservoir Shock 14.14in Travel Eye to Eye

Vehicle Fitment

• Universal - No specific OEM vehicle application assigned
• Designed for custom-built, modified, or specialty off-road vehicles requiring a specific shock travel length and eye-to-eye mounting
• Verify collapsed and extended lengths against your vehicle's suspension geometry before ordering

Fitment Notes

• This is a universal shock sold by travel length and valve rate - fitment is determined by the builder, not by year/make/model
• Both upper and lower mounts are Eye 5/8 in. with hourglass bushings - confirm mounting hardware compatibility with your application
• Valving rate: Medium - suitable for a broad range of light truck and SUV custom suspension builds
• Reservoir mounting hardware included; optional billet aluminum reservoir clamp available separately (Bilstein #11176015)

Features

• 46mm monotube design delivers consistent, fade-free damping for demanding custom and off-road applications
• External remote reservoir provides increased oil capacity and heat dissipation for extended, high-intensity use
• Linear piston valving with medium tune offers predictable, controlled damping across a wide range of custom builds
• 360-degree swivel banjo hose fitting allows flexible reservoir routing in tight or custom chassis environments
• 5/8 in. hourglass bushings on both ends for secure, low-NVH mounting in custom fabricated brackets
• Zinc-plated body provides long-term corrosion resistance in harsh off-road environments

Product Description

The Bilstein B8 5165 25-331707 is a universal remote reservoir monotube shock absorber designed for custom-built and modified off-road vehicles that require a specific shock length and travel not covered by vehicle-specific catalog applications. With 14.14 inches of travel, a 20.65-inch collapsed length, and a 34.79-inch extended length, this shock is intended for builders who have confirmed their suspension geometry and need a high-performance reservoir shock to match. The 46mm monotube body with medium linear valving delivers consistent, controlled damping across a broad range of custom truck and SUV suspension setups.

Both ends use 5/8-inch hourglass bushings in an eye-to-eye configuration, making this shock compatible with a wide variety of custom fabricated brackets and OEM-style mounts. The remote reservoir significantly expands oil volume and heat dissipation over a standard shock, supporting sustained off-road cycling without fade. As with all B8 5165 series shocks, fitment is the builder's responsibility - always verify collapsed and extended lengths match your suspension travel before installation.
