Do you have a V6 or V8? I have a V8 with Taco TRD pro coils and 5100s, the front end feels too squishy for my liking. I bought the truck like this and I'm looking to go with a full Dobinsons kit soon. Seems like the better way to go, because if you get the monotube or remote reservoir shocks they can be rebuilt, plus you can chat with them and get the springs ordered so they give you exactly the lift you want. They have SO MANY spring options. 5100s can't be rebuilt.
Probably not exactly what you're looking for but I figured I'd throw that out there. IDK why anyone would use V6 springs on a V8. The spring rate simply isn't there.
