The 2.5 DC PIGGYBACK 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 remote reservoir directly attached to the shock body with increased oil volume for cooler operating temperature, providing better performance and consistency.
This configuration is optimized for use with stock geometry or can be used with lift kits between 0 in. to 2 in. that use stock length shocks (with or without relocator brackets).
Ride height is not affected by the installation of these shocks.
Package includes two (2) side-specific rear shocks:
- High-Speed Compression
- Low-Speed Compression
**All Elka Suspension components are made to order. Please contact us for current lead times. We will contact you at time of order to learn about the specifics on your build so the suspension is properly tuned to your vehicle.
