Heavy-Duty Rear Shock Upgrade – KONI EVO FSD for Freightliner M2 / S2RV Super-C

Upgrade the ride quality and suspension control of your Super-C motorhome with the KONI 9905-1038 EVO Rear Shock, engineered for the 2014-Current Freightliner M2 Super-C and 2018-Current Freightliner S2RV Super-C chassis. Designed specifically for heavy motorhome applications, these shocks feature KONI EVO technology that delivers improved ride comfort, enhanced stability, and long-lasting durability.

KONI EVO shocks utilize patented open intake valve technology which allows the suspension to absorb small road imperfections smoothly while still providing strong damping force during large suspension movements. This creates a ride that remains comfortable over expansion joints and rough pavement while maintaining excellent control during braking, cornering, and highway driving.

The EVO series incorporates a large 50mm piston, nearly 40% larger than the piston used in traditional FSD shocks (36mm). The larger piston allows the shock to manage higher suspension loads while operating at lower internal pressure, improving cooling, responsiveness, and overall durability.

With increased oil capacity, heavy-duty construction, and advanced digressive valve technology, the EVO series delivers superior body control, smoother ride quality, and longer service life for heavy Super-C motorhomes.

If your motorhome experiences rear suspension bounce, instability, or poor ride control, upgrading to KONI EVO shocks can significantly improve ride comfort, handling stability, and driver confidence.

Product Benefits:

EVO technology improves ride comfort and suspension control
Large 50mm piston increases durability and damping performance
Patented open intake valve design improves small-bump ride quality
Reduces rear suspension bounce and harsh ride characteristics
Improves vehicle stability and chassis control
Designed specifically for Freightliner Super-C motorhome chassis

Ideal For:

Freightliner M2 Super-C motorhomes
Freightliner S2RV Super-C motorhomes
Replacing worn factory rear shocks

Long-distance RV travel

Applications:

2014-Current Freightliner M2 Super-C – Rear Axle
2018-Current Freightliner S2RV Super-C – Rear Axle

Note: This shock does not fit vehicles equipped with Hendrickson PRIMAAX rear suspension. Please verify your rear suspension type prior to ordering.

The KONI 9905-1038 EVO rear shock is engineered specifically for Freightliner Super-C motorhome chassis and provides improved ride comfort, durability, and suspension performance compared to many factory-installed shocks.
