Heavy-Duty Rear Shock Upgrade – KONI Adjustable for Ford F53 ’88–’98, Country Coach / Gillig / Freightliner Chassis, Leaf-Spring Rear

Upgrade the suspension performance of your motorhome with the KONI 88-1668SP1 Heavy-Duty Adjustable Shock, designed for 1988-1998 Ford F53 motorhome chassis equipped with the 7.5L 460 V8 engine. These premium KONI heavy-duty bus shocks are engineered to improve ride control, stability, and durability—especially important for gas Class A motorhomes and heavy RV applications.

Unlike standard replacement shocks, KONI adjustable shock absorbers feature manually adjustable rebound damping, allowing you to fine-tune suspension performance to match your coach weight, driving style, and road conditions. Whether you're looking for improved highway comfort or better control on rough roads, these shocks allow you to dial in the ride quality that best suits your motorhome.

The adjustable rebound design also allows you to increase damping as the shocks wear over time, helping extend service life while maintaining consistent ride performance. Combined with KONI’s heavy-duty construction, these shocks provide excellent control over large suspension movements while still delivering a comfortable ride on long highway trips.

If your motorhome experiences excessive bouncing, body roll, or poor suspension control, upgrading to KONI adjustable shocks is one of the most effective ways to improve ride comfort, highway stability, and driver confidence.

Manually adjustable rebound damping for customized ride control
