Koni EVO 99B-3234 - 2000-2017 Spartan MountainMaster IFS1460 14K to 16K Front / 2004-2017 Spartan MountainMaster IFS1660 16K/17K Front / 2008-2010 Tiffin Allegro Bus w/ PowerGlide Chassis w/ Reyco IFS Front
Some Spartan front IFS systems use a lower shock mounting bracket that is not compatible with the Koni mount. When replacing Bilstein part# BE5-6199-H0, BE5-6199-H1 or 24-061999 you may need this kit.
If your lower mount uses a "pin" instead of a bolt in the lower shock mount you will need to order x2 of part # APK-10000
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.
Performance parts should last, and Koni EVO 99 shocks can go the distance with our industry leading 9 T tensile strength. We back our products up with a lifetime warranty for the original purchaser.
