KONI EVO Rear Shock for 2007-2010 Chevrolet Kodiak C5500 w/ 19K Rear Springs (Part # 99B-3174)

Improve ride quality and suspension durability on your Kodiak-based motorhome or commercial chassis with the KONI 99B-3174 EVO Rear Shock, engineered specifically for the 2007–2010 Chevrolet Kodiak C5500 with 19,000 lb rated rear springs and pin-to-pin mounting. Built using KONI’s latest EVO shock technology, this heavy-duty shock absorber delivers superior ride comfort, improved stability, and exceptional durability for heavy truck and RV applications.

KONI EVO shocks incorporate patented open intake valve technology that allows the suspension to react smoothly to small road irregularities while still delivering strong damping force during larger suspension movements. The result is a ride that absorbs rough pavement and expansion joints comfortably while maintaining excellent chassis control during braking, cornering, and highway driving.

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

With increased oil capacity, stronger internal construction, and advanced digressive valve technology, the EVO series provides better body control, smoother ride characteristics, and longer service life for heavy-duty Kodiak C5500 chassis used in commercial trucks, Super-C motorhomes, and specialty vehicles.

If your vehicle experiences rear suspension bounce, harsh ride quality, or reduced suspension control, upgrading to KONI EVO shocks can significantly improve ride comfort, stability, and overall driving confidence.
