The Radflo 2.5 Bypass Shock with Remote Reservoir is built around a 2.5" shock body, heavy-duty 7/8" shaft, four externally adjustable bypass tubes, and a large remote reservoir. When paired with Radflo coilovers, it gives builders and tuners the ability to create a softer ride in rough terrain while increasing control near full compression and extension.
The four external bypass tubes allow suspension tuning without disassembling the shock, making it easier to dial in ride quality, bottom-out resistance, chassis control, and overall suspension performance for your specific vehicle.

Note: Proper mounting dimensions, valving setup, and bypass tube orientation must be confirmed for your specific vehicle.
1. What is the difference between a bypass shock and a coilover shock?
A coilover supports vehicle weight using a spring while providing basic damping control. A bypass shock is designed to tune suspension performance throughout the travel range, providing additional control over compression, rebound, and bottom-out resistance.
2. Why does this shock have four bypass tubes?
The four external bypass tubes create separate damping zones throughout the shock stroke. This allows tuners to adjust ride quality, chassis control, and impact management without disassembling the shock.
3. Do bypass shocks replace coilovers?
No. In most suspension systems, bypass shocks work alongside coilovers. The coilover supports the vehicle while the bypass shock provides additional tuning and control.
4. What vehicles benefit most from a 2.5 bypass shock?
These shocks are commonly used on rock bouncers, Ultra4 race cars, prerunners, off-road race trucks, and high-performance trail rigs where suspension tuning and impact control are critical.
5. Are Radflo 2.5 Bypass Shocks rebuildable?
Yes. Radflo bypass shocks are fully rebuildable and serviceable, allowing long-term maintenance and suspension tuning as vehicle requirements change.
