Definitely worked for what I needed them for. Raised out food truck considerably higher. Also improved drivability and ride comfort. Would definitely recommend this product.

Hello, I used the sumo spring for a number of years on my Mitsubishi Rosa 25 seater Bus , The bus weight is 8 – 10 thousand lbs. and I used the black sumo spring.How ever I do think I need to step it up a bit to the more harder sumo spring the yellow spring, so I would like to try them on the bus
I also purchased the super leaf spring. i thinking it was the SSA39 or the next one up from that. How ever it is for an over spring axel and mine is an under-axel leaf spring. System. also, they are short in length. I need a 54 inch from eye to eye round to fit.
So, what is your suggestions to help my leaf spring problem?
