How to Choose

Dual shock performance in a single shock configuration
For maximum performance and minimum compromise, our highly advanced bypass shock absorbers combine position sensitive external adjustment with velocity sensitive internal valving. Softer damping during initial travel maintains comfort and control, while firmer damping during the last few inches resists harsh bottoming out.

External bypass chambers are easily adjusted for ultimate damping control
Position sensitive damping is controlled externally by individual metering tubes that allow precise amounts of oil to bypass the shock piston. Designate the number and location of bypass tubes to match your performance requirements. In a matter of seconds, each tube can be easily adjusted to alter compression, rebound or bleed resistance at specific travel sectors.

Velocity sensitive valving automatically adjusts to terrain for improved control, handling and comfort
Radflo's exclusive Freeflo™ racing piston utilizes adaptive damping technology to automatically match shock performance to surface conditions. Multi-stage compression and rebound damping characteristics can be independently customized to suit your vehicle setup and driving preferences.

Exceptionally strong piston rod assembly designed for the harshest off-road racing conditions
Available in 7/8" and 1" diameters, our Nitro Steel® rod and slippery bronze rod guide provide unyielding performance in the roughest terrain. Multi-direction, triple lip sealing system prevents oil contamination while ensuring excellent gas and oil retention.

Completely rebuildable, serviceable and tunable for virtually unlimited service life
Because all shocks wear out eventually, we designed every single component to be easily serviced or replaced. Even the individual valve shims can be changed to fine-tune damping performance. Our highly experienced technicians can perform these services, or you can service the shocks yourself for immediate results.
