Sumo spring blue SSR-610-40 vs SSR-612-40

Like I mentioned before. I have a set, thst was on truck for one month. Pulled trailer empty 250 miles and back full 250 miles. Otherwise no use/contact on them. I traded truck in. I'll sell them to you $150. If interested pm me and I'll send you pics. Also have two set of seat- jackers.

 

I’m good. I think we are a long ways apart.

 

I would be interested in buying them for my son's truck. I don't mind shipping as they have to be shipped anyways, not like you can get them from the auto parts store on the corner.

 

So did you end up going with the newer 612 model? I have a 2022 SR access cab and definitely want something in the back to help with towing. I have a 19 foot boat, not sure about tongue weight but probably in the 400 lb range. I am debating between all the different models of sumosprings, airbags, or AAL / different leaf pack. If you ended up with the 612 sumospring, how does it compare to the older model?

 

You want the 612 model. The 610's will be touching all the time, which will give you rough ride empty. 612's will be 1/2 to 3/4 inch from frame when bed is empty.

 

I have the 612s and love them. Takes the squat out of towing.
