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!

Great soft ride!

So I’m coming from a BDS 6in progressive spring to the Thuren 6in Spring. I also replaced the track bar with Thurens as well. I can’t tell you how much night and day difference it was between the 2. I’m still running the same Fox 2.0 shock as well so that wouldn’t be the result. It’s amazing and I’m so happy I made the switch! Can’t beat the price either.
