FRONT *High Force* Koni EVO Shock for Spartan and Tiffin PowerGlide with Reyco Granning Independent Front Suspension (Part Number 99B-3234SP1)

Front Heavy-Duty Shock Upgrade – KONI EVO High Force for Spartan K2 / K3 / MountainMaster with Reyco IFS1460-IFS2000 and Tiffin Allegro Bus Reyco IFS

This is the High Force version of the 99B-3234. It can be used on the same applications as the 99B-3234 but it has firmer valving to provide even more control for coaches that have extreme front end "bounce".

We recommend the High Force EVO on 18K+ front axle ratings or if heavily loaded to near max GVWR on the lighter coaches.

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. Our 50mm bore piston reduces internal pressure for smooth operation over rough roads, and our digressive valve stack and modular piston design control bouncing over bridges and large bumps.

The main difference between the 8805 and the 99 series piston is that it is almost 40% larger than the 8805 series (50 mm vs 36). Which means it can take a lot more force, or the same force with less pressure. This improves durability and performance. The 99 series is also Koni's latest shock design. It was developed for high end motorcoaches in Europe, and Koni is just starting to introduce it in America in the RV market. Both shocks control up and down movement, but Koni has found a better balance between the two with the 99 series setting.
