Koni 99B-3234

Please Note:

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 


Ride Quality:

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.


Durability:

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.

Worldwide Reputation:

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.

lOOKING FOR KONI SHOCKS FOR THE FRONT, DO YOU HAVE THEM IN STOCK AND WHAT IS THE PART NUMBER ( Brent Jarrett, 11/02/2023 )
Hello Brent, we don't have a Spartan Vin catalog to look those up, and also the VIN is missing a digit ( should be 17) .  If you can confirm what suspension you have or get part #'s off existing shocks, we can help determine the correct part # for the Koni shocks.  ( Support )

Which Koni shocks do I need and do I need the additional mounting bracket. ( Frank Rainey, 06/21/2023 )

Hello Frank,  due to the various suspension options on Spartan chassis, we recommend getting part #'s from Spartan (or off original shocks)  and we can check for a Koni application.

I have a 2010 Newmar Dutch star model 4304. It has a spartan chassis with a tag axle. The front axle model number is 68400002. The s/n is AXIF00337. It has bilstein front shocks and I am not happy with the ride. Seems to be very harsh on rough road and bouncy on frost heaves. I am wondering it you have a shock that will be better suited available for this front end. Thx ( Duane Hoflin, 03/03/2023 )
We checked with Spartan and you have a Hendrickson Independent Front Suspension which, unfortunately, we do not have a Koni application for. ( Support )

This is a Spartan tag axle chassis with a Rayco-Granning IFS1460. It is under a Newmar Mountain Aire 4304 Diesel RV. Can you give me Koni Evo shock numbers for all the shocks on the coach please? Also, will I need the shock bottom adapter brackets for the front? Are the brackets sold and priced each or per pair? Thanks! ( Doug, 04/14/2022 )
Hello Doug, we contacted Spartan with that VIN and have Koni #'s for the steer axle and drive axle. The front shocks are 99B-3234 and the drive axle shocks are the Koni FSD's , # 8805-1009 . According to Spartan that chassis doesn't have a tag axle, if it does, you may need to double check the VIN . They also said you MAY need the lower brackets. To verify the brackets, you will need to check the existing lower mounts. 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

I have a 2008 Tiffin Zephyr with Spartan K2 chassis. Wil the 99b-3234 Front shacks fit my coach?

also this is a Tag axle 45 foot coach. which ones fit the rear?
( charles letchman, 05/06/2021 )
Spartan lists the following Koni shocks for your coach: Front 99B-3234, Rear Drive 8805-1009 but they don't list a Koni option for the tag axle. We think that 8805-1013 would probably work but would need a part # off the original shock to verify. ( Support )

I have a 2020 Newmar 41' motorhome on a Spartan K-2 chassis. It came with Bilstein 24-186414 shocks on the front and it bounces like crazy on bridge and overpass joints on the freeway. Does this 99B-3234 shock fit and will it help to control this bounce?

Thank you
( Jeff Brannon, 03/22/2021 )
Hello Jeff, the Bilstein 24-186414 crosses to  a 99B-3254 on our website, and the Koni "EVO"  99 series is specifically designed for the large I.F.S. RV's and busses and definitely help control the front end bounce while giving a smooth ride.
