High-Performance Upgrade over OE shocks with Dual-Compression External Adjusters

The 2.5 DC RESERVOIR shocks provide the optimal combination of:

  • Firm and stable handling for driving on desert and fire roads;
  • Plush compliance while off-road driving over washboard;
  • Strong ramping effect for extra bottom-out protection over large dips and washes;
  • Maximum articulation and traction for rock climbing.

The 2.5 DC RESERVOIR model allows precise fine-tuning of the high-& low-speed compression damping so you can adapt the suspension for your specific driving style and terrain conditions without compromise. It also features an external reservoir with increased oil volume for cooler operating temperature, providing better performance and consistency

2.5 DC RESERVOIR // ADJUSTMENTS

HIGH-SPEED COMPRESSION

Allows fine-tuning of the damping resistance when the shock is being compressed quickly. This adjustment controls the resistance upon landing from jumps, harsh or sudden square-edged impacts, riding at high speed over whoops, choppy terrain or tire tracks.

To use, turn the black knob clockwise to increase damping resistance, therefore making the suspension stiffer or turn counter-clockwise to reduce damping resistance, therefore making the suspension softer.

LOW-SPEED COMPRESSION

Allows fine-tuning of the damping resistance when the shock is being compressed slowly. This adjustment controls body roll when cornering, squatting under hard acceleration, front-end diving when braking, riding over whoops at moderate speed, undulations and elevation changes in the terrain.

To use, turn the red knob clockwise to increase damping resistance, therefore making the suspension stiffer or turn counter-clockwise to reduce damping resistance, therefore making the suspension softer.

THREADED SPRING PRELOAD
(COILOVER MODELS ONLY)

Lets the driver fine-tune the initial force applied on the springs and precisely balance the weight distribution across the front and rear wheels while setting up the ride height (ground or chassis clearance) and to lower or raise the vehicle to adapt to various situations or to suit your personal preference. To use, turn the preload adjustment ring clockwise (from top of the shock) to increase preload and raise the vehicle or turn counter-clockwise to reduce preload and lower the vehicle.
