Cut down vibration and shock on air ride suspension systems

Rigs equipped with air ride axle suspensions still produce substantial vibration and shock. By adding the CRK 20 Air Ride Upper Coupler to those rigs you can dramatically smooth out the ride.

Many tests have been conducted by organizations such as General Electric and the US military. Tests prove that the CRK 20 reduces vibration and shock by at least 50% on rigs equipped with air ride suspensions and 80% on rigs with steel sprung suspensions.
