Soft as can be

Recently installed these springs and all I can say is how soft they ride. Old springs rode like complete crap and I only realized until I installed these. Very well made and can tell Thuren knows these trucks well

Night and day

World of a difference from the bds coils I had. So much that you now notice the back of the truck rides terrible. Looks like I’ll be doing deavers next. 10/10 recommend. 1998 ram 2500 Cummins

Best of the best!

I have now had the 6” soft rides with Fox shocks on my truck for almost a year. I cannot speak highly enough of the quality of this product. I’ve owned many different trucks with many different brands and variations of springs and I have to say these are the best out there. Highly recommend and will be a repeat customer!

Great product

Really softened up the ride on my 99. Every Ram truck I ever have from here on out my first modification is going to be a set of Thuren coils. Wish I would have done it sooner!
