Radflo 2.5 DRT Internal Bypass Coilover Shock

Radflo 2.5 DRT Internal Bypass Coilover Shock is a universal coilover shock, not vehicle specific. Pick your travel length and adjuster above. Each option is its own Radflo part number, listed in the chart below.

External bypass performance in a single smooth-body or coil-over unit provides race truck level control and confidence, no matter your application.

Proprietary RST Dynamic Ride technology dampers provide both velocity and position-sensitive damping in a single unit, with a progressive ramp-up for comfort and ride quality while also increasing control for bottom and top-out events. This allows the vehicle to float over small bumps and chatter while maintaining that bottomless feeling, even when going fast through the big stuff.

Custom adjustments: custom spec main piston valving (compression and rebound) and custom spec internal bypass (DRT) valving (compression and rebound).

Compression ride zone: this zone controls the amount of bypass initially introduced on compression and the rate at which the suspension compresses. This is ideally the middle of the travel, where the piston sits at ride height +/- a certain percentage. While in the ride zone, the oil can bypass the main piston through the proprietary DRT valves, generating minimal high-speed damping.

This shock is picked by dimensions, not by vehicle. Confirm collapsed length, extended length, mount types, mounting widths, bolt sizes, reservoir placement, hose clearance and chassis clearance before ordering. Also confirm spring inside diameter, free length, rate, hardware and available preload range.

Every version comes with a remote reservoir. Choose the compression adjuster version (part numbers ending in 9A) or the dual compression adjuster version (part numbers ending in 9Z).
