The Radflo Off-Road 2.5 Bypass Shock with Piggyback Reservoir (3-Tube) combines position-sensitive external bypass tuning with velocity-sensitive internal valving, delivering true dual-stage performance in a single shock package.

Softer damping during initial travel maintains comfort and traction, while firmer damping near the end of stroke resists harsh bottom-outs at speed. The 3-tube external bypass system allows precise adjustment of compression, rebound, and bleed characteristics at specific points in the travel, giving you race level control over how the suspension reacts in real terrain.

At the core is Radflo’s exclusive Freeflo® Racing Piston, which uses adaptive damping technology to automatically match shock performance to surface conditions. Combined with a 7/8" Nitro Steel® shaft, CNC-machined bronze rod guide, and a multi-direction sealing system, this shock is engineered to survive extreme abuse while remaining fully serviceable and tunable.

Availability Note: As the #1 Stocking Warehouse for Radflo, we maintain the largest on-shelf inventory of shocks in the industry. While we keep the most popular lengths ready for immediate shipment, the high demand for specialized sizes can occasionally result in a lead time on shocks that get ordered.

We are committed to getting your rig on the trail as fast as possible. If your build schedule is critical, please call us to confirm real-time inventory before placing your order.

Final tuning should be matched to vehicle weight, suspension geometry, and intended terrain

Bypass shocks blend position sensitive damping (external bypass tubes) with velocity sensitive response (internal valving), delivering unmatched control across slow crawling, high speed desert runs, and hard impacts.

The 2.5 shock body increases oil volume and thermal capacity, while the piggyback reservoir improves cooling and consistency during prolonged abuse. Radflo’s built-to-order valving ensures this shock performs exactly as intended for your specific setup with no compromise, no guesswork.
