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  // BENEFITS

  • Wide range of highly effective compression adjustment
  • Precise fine-tuning of high-& low-speed compression, no need to compromise with your settings
  • High-performance off-road capabilities
  • Improved handling and comfort for casual driving
  • Better traction

  • Provides leveling capabilities for better weight distribution

  • Increased protection against bottoming-out

2.5 DC RESERVOIR // AVAILABLE CONFIGURATIONS

  • 2.5 Front & Rear shocks kit

  • 2.5 Front shocks only

  • 2.5 Rear shocks only

  • Coilover version or damper only depending on vehicle model/year and position

2.5 DC RESERVOIR // RIDE ENHANCEMENTS

  • Better attenuation of vibration, leading to major noise reduction in the cabin (much less squeak and rattle)

  • Damping characteristics optimized for each truck and setup, providing a smoother ride

  • Increased comfort in both on road and off-road conditions, especially over washboard and square-edge impacts
  • More stable and more predictable handling

  • Reduced front-end diving when cornering or braking

  • Reduced rear-end bucking and lifting

  • Increased damping and spring rate for better handling when towing or loading truck

2.5 DC RESERVOIR // TECHNICAL FEATURES

  • Massive 2.5 in. (56mm) hard-anodized aluminum body for cooler operation

  • External remote reservoir with low-friction floating piston (1:1 ratio vs. main piston) providing additional cooling with DOT high-flow reservoir hose

  • Gas-pressurized design with internal floating piston to help prevent fading
  • Internal hydraulic valving optimized for each vehicle platform
  • Built from CNC-machined and forged aluminum parts, aluminum bodies and premium-quality internal components
  • Heavy-duty 3/4 in. (19mm) induction-hardened shaft
  • Triple sealing system with dust wiper, high-pressure step-seal and premium quality o-ring
  • Direct, bolt-on replacement that uses stock shocks location
  • Proprietary ultra-low friction, light viscosity semi-synthetic oil blend, ultra-resistant to high operating temperature
  • Coilover models use Elka’s durable high-tensile alloy springs or Eibach springs (depending on model & configuration)

  • Fully rebuildable using affordable replacements parts and springs, multiple replacement valving shim stacks available

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.
