Riding on Air from Source Engineering

Consisting of new proprietary Firestone air bags and custom Bilstein shocks engineered specifically for this kit, the REK-202 also incorporates a reserve ping tank and 5⁄8-inch air lines in the front suspension. According to the company, the Firestone air bags have more travel than the original bags, while the larger air lines and ping tank provide more air volume for the front suspension. This in turn softens the ride without compromising handling.

As with the TRA-1003 trailing arm kit installation, we photographed the Ride Enhancement Kit installation at Redlands Truck and RV in Redlands, Calif., an authorized Source Engineering dealer. We were given the opportunity to drive the coach with the stock suspension in place first, then give it another try after the kit was installed so we could experience the difference.
