Radflo DRT 2.5 Internal Bypass – Remote Res. (WOD Custom Mount Height)
6CV-004-9Z-1
The Radflo 2.5 DRT Internal Bypass Coilover with Remote Reservoir and 14" Travel is a custom Wide Open Design configuration built to deliver advanced suspension control in a compact package. Designed specifically for WOD, it uses the mounting height of a Radflo 2.0 coilover, allowing a 2.5" DRT coilover to fit tighter suspension and chassis packaging. These DRT Coilovers are the same shocks that WOD uses on custom builds.
Position-sensitive internal bypass damping provides a compliant ride through smaller terrain while increasing control deeper in the travel for hard impacts and bottom-out resistance. A remote reservoir improves heat management, while high- and low-speed compression and rebound adjusters provide extensive external tuning capability ideal for rock crawling, Ultra4 competition, desert racing, prerunning, overlanding, trail riding, and custom off-road applications.

Tech Insight
What is the difference between internal bypass and external bypass shocks?
External bypass shocks use visible bypass tubes mounted outside the shock body. Internal bypass shocks create the damping zones inside the shock body.
Internal Bypass Advantages:
- Easier packaging
- Cleaner installation
- Less maintenance
- Better fitment in tight chassis
External Bypass Advantages:
- Maximum external tuning
- Greater adjustability for race teams
For most enthusiasts and racers, DRT Internal Bypass delivers exceptional performance without the packaging challenges of external bypass shocks.
What do High-Speed Compression (HSC) adjusters do?
High-Speed Compression affects how the shock responds to:
- Rocks
- Whoops
- G-outs
- Jump landings
- Square-edge impacts
Increasing HSC creates more impact resistance and bottom-out control.
What do Low-Speed Compression (LSC) adjusters do?
Low-Speed Compression affects:
- Body roll
- Brake dive
- Acceleration squat
- Steering response
Increasing LSC creates a more controlled and stable chassis feel.
What do High-Speed Rebound (HSR) adjusters do?
High-Speed Rebound controls how quickly the suspension extends after larger impacts.
Adjusting HSR helps:
- Control bucking
- Improve stability
- Manage suspension recovery after hard hits
What do Low-Speed Rebound (LSR) adjusters do?
Low-Speed Rebound affects:
- Vehicle balance
- Weight transfer
- Chassis stability
- Cornering behavior
Fine-tuning LSR allows drivers to dial in handling characteristics for specific terrain.
