2014 Tiffin bus, 37AP… power glide chassis…can you tell me what Koni shocks to order, front and rear? ( Ellen Endicott, 01/27/2025 )

Your coach should have the ZF independent front suspension, we can verify this for you if you send a picture of the original shock. Front would be Koni 99B-3262 and rear would be 8805-1009.

I did the 1 1/8" wrench test and it was not snug. So does that mean I need the 16ea. spacers for rear shocks? The shocks for front are the 99B-3234 are this the new upgraded model? The back are 8805-1009 correct. Thanks ( rc thomas, 03/03/2024 )

Yes, if the wrench did not fit tight then you will need the spacer kit, you just need to order quantity 1 to do the lower bolt on each side. 99B-3234 is the new EVO model shock for your application.

Will an oversize Koni fit on my Spartin chassis . I have a 2019 entegra Aspire, the original buyer quickly installed larger Koni shocks on the front but not the rear. Is this a ride problem as far as porpoising is considered or maybe he did not do the rear because in just looking at the front Konis and then observing the amount of clearance between shock and the frame member it seems as a maybe fit at best for the larger Koni? I,m looking at maybe a half inch. ( John Pepper, 10/01/2022 )

Hello John, the the larger diameter Koni "90 Series" are for front applications, primarily for Independent front suspensions, which place more leverage on the shocks and need more damping due the increased leverage. The 8805-1009's are the "FSD" design and work well on the rear application as they are "self adjusting" too give control when needed and still provide good ride quality .

Looking for larger size shock than standard on my 2019 entegra Aspire 40 foot. More like the 60MM size, Will they fit? ( John Pepper, 09/26/2022 )

Koni 99B-3234 front and Koni 8805-1009 rear will fit your Entegra Aspire.

I have a 2013 Tiffin Phaeton 36GH. I think she requires 2ea 99B3209 shocks for the front and 2ea 8805 1009 shocks for the rear. Can you verify or correct this information? ( Bill Milman, 09/02/2022 )

Your coach will take the 8805-1020 front shocks and 8805-1022 rear shocks.
