Koni 9905-1029

Description:

Experience a smooth controlled ride on your Class A motor home with Koni EVO 99 shock absorbers. Koni's patented open intake valves ensure that you get a smooth ride along with enough force to keep your RV from bouncing down the road. EVO 99 is especially good on independent front suspensions that have a limited amount of shock travel. Large piston holes and custom tuned valve stack ensure that you have extra body control when you need it without undue harshness. You don't want poor road conditions to spoil your cross-country trip. The 50mm bore piston reduces internal pressure for smooth operation over rough roads, and the digressive valve stack and modular piston design control bouncing over bridges and large bumps.

The EVO series is Koni's latest shock design. The main difference between the FSD and the EVO series piston is that it is almost 40% larger than the FSD series (50 mm vs 36 mm). The larger size means that it can take a lot more force, or the same force with less pressure which helps with cooling and better responsiveness. The larger body diameter allows for more oil capacity which also helps with cooling and increases the longevity of the shock. EVO series has a higher tensile strength than previous Koni designs. EVO incorporates open intake valves + FSD technology which exceeds the performance of FSD technology alone.
