This is the New Front Heavy Duty replacement shock for the 8805-1021 used previously on the front axle of the Alpine Peak, Roadmaster RR4R, Workhorse UFO & Spartan MountainMaster I-Beam chassis. It became evident after a few years that the 8805-1021 just wasn't holding up to the weight and demands of these chassis. The Koni engineers went to work and did real world testing to come up with a shock that would increase the ride comfort yet be built to withstand the most punishing demands thrown its way.
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 motor coaches 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.
Koni is known as the shock absorber specialist worldwide. We have committed ourselves to delivering the finest quality product with the best performance. This philosophy results in unrivaled durability, superb road performance and maximum customer satisfaction.

Koni Frequency Selective Damping (FSD) shock absorbers provide superior handling characteristics without compromising ride comfort. The FSD is firm where you need it, such as through corners, but rides soft over expansion joints and rough roads. A special valve filters out annoying vibrations before they enter the vehicle, resulting in a smooth ride over a variety of road surfaces.
