Elka 2.5 RESERVOIR FRONT & REAR SHOCKS KIT for TOYOTA 4RUNNER, 2010 to 2020 (non-KDSS) (2 in. to 3 in. lift)


Please note that this is not a complete "lift kit". You will still need to purchase rear springs if you plan on lifting the rear of the vehicle.

The 2.5 RESERVOIR model features an external reservoir with increased oil volume for cooler operating temperature, providing better performance and consistency. These shocks are a good performance upgrade over OEM shocks.

This configuration is for use exclusively with aftermarket lift kits or upper control arms to accommodate between 2 in. to 3 in. of lift.

Ride height is preset from our factory at approximately 2.5 in. of lift at the front for most setups, actual ride height may vary depending on wheels dimensions and lift kit or upper control arms used.

Package includes four (4) position-specific shocks:

  • Two (2) 2.5 RESERVOIR Coilover front shocks
  • Two (2) 2.5 RESERVOIR rear shocks

Increase the off-road capabilities while improving the comfort and handling of your 4Runner

The 2.5 RESERVOIR shocks provide the optimal combination of:

  • Firm and stable handling for driving on desert and fire roads (sports car feeling);
  • 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.

  • Improved handling and comfort for casual driving
  • Better traction
  • Provides leveling capabilities for better weight distribution
  • Increased protection against bottoming-out


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

  • 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


  • Massive 2.5 in. (56mm) hard-anodized aluminum body for cooler operation
  • Big bore design with less restricted oil flow for increased responsiveness and less fading
  • Internal hydraulic valving optimized for each vehicle platform
  • Built from CNC-machined and forged aluminum parts, aluminum bodies and premium-quality internal components
