Tiffin says they install KONI as OEM on '22 Bus (40ip) now however I have way too much bounce and sway after 22000 miles. Are these and upgrade to factory ( Robert F Averitt, 11/10/2024 )
From what we understand, the OEM supplied Koni's do not have the same valving/damping as the aftermarket EVO's so you probably would notice an improvement by switching. You could also invest in Motion Control Units to help stabilize the coach: https://www.ultrarvproducts.com/Airbag-Control-Units
Will these front shocks work on a 2024 Entegra Reatta? ( Justin Miller, 10/16/2024 )
Hello Justin , we do not have a VIN catalog for the Spartan chassis.  If you can get existing shock part #'s from the shocks or by contacting Spartan , we may be able to cross them to a Koni #.  
Does the 3264 fit this vin? TIA Joe ( Joe Mckay, 07/20/2024 )
Yes, the 99B-3262 is correct for your vehicle.
I have a 2016 Allegro Bus. Does this fit my rear shocks? ( Ellis Skinner, 04/16/2024 )

Please see the note about lower bolt size on the product page. 
Are the 99B-3262 correct for shocks for my Coach? ( Greg J Albin, 10/09/2023 )

Hello, can you double check the VIN ?  When I run the last 6 I get :  4UZFCHCY8CCBV6161  As long as that is correct, those are correct for the application as well.
