My bump stop kit is from SVC. They were pretty sure with my set up of Deaver +3 rear leafs and using the truck but but not heavy jumping the Fox 2.0's would come in smoother and still do a nice job on full compression...
There are all sorts of opinions on which is better "Fox or Kings"...the truth is both make high end shocks found on all sorts of winning Trophy Trucks. Either shock will work great on our trucks, but the difference between great ride and handling is NOT which shock, but the spring and valving.
I like to recommend a shock vendor that has taken the recommended shock from either company and then taken the time to R&D the spring and valving even more...you pay a little more but if its done correctly you will have a great ride and control from King or Fox....
