Heavy-Duty Front Shock Upgrade – KONI Adjustable for 1997-2006 Spartan MountainMaster IFS1200–IFS1360


Upgrade the ride quality and suspension control of your motorhome with the KONI 90-2815 Adjustable Front Shock, designed for Spartan MountainMaster chassis equipped with Reyco Granning Independent Front Suspension. These heavy-duty adjustable shocks improve steering stability, reduce front-end bounce, and deliver better chassis control for large diesel motorhomes.

KONI adjustable shock absorbers feature manually adjustable rebound damping, allowing the suspension to be tuned to match the weight and handling characteristics of your coach. This adjustability provides improved ride comfort and better control compared to standard non-adjustable shocks.

The adjustable rebound feature also allows damping force to be increased over time as the shock wears, helping maintain optimal suspension performance and extending the service life of the shock absorber. Combined with KONI’s heavy-duty construction and precision valving, these shocks deliver excellent durability and long-term reliability for demanding motorhome applications.

If your motorhome experiences excessive front-end bounce, poor steering stability, or worn factory shocks, upgrading to KONI adjustable shocks can significantly improve ride comfort, suspension control, and driver confidence.

  • Manually adjustable rebound damping for customized ride tuning
