First, thank you for trying SumoSprings, to assist with your vehicle suspension. We’re happy to hear they’re working out so far.
I’m not too familiar with a popping sound coming from the SumoSprings, so I have a couple questions. If this is on a Ford F-53 chassis, what is the year, coach make, and coach GVWR?
If not, what is the year, make, and model of the chassis? Also, with that information, I’d like to know the part numbers of the SumoSprings kits you had installed.
With this information, we can proceed as necessary. You can also email me at [email protected].
