Leaf Spring - Input Needed
Leaf Spring - Input Needed
I've called a few dealerships and they don't have much info on the actual difference between the leaf springs, other than being able to tell me which vin matches up to a specific code spring.
I ended up pulling a couple VIN #'s from him, one from a XLT without max tow package and one from platinum w/max tow package and the XTL had (-A) springs and Platinum had (-C) springs and I'm hoping someone has some useful info regarding spring rate/stiffnessfor each since I'm trying to find the softer spring to replace onto my truck

I would look at the springs on an absolutely stripper base 2WD 122 Regular Cab. 6010 GVWR. That should be the softest and possibly least arch. Im not sure if rear springs have different arches like the front's have different free lengths but I suspect they do to adjust ride height. You likely are looking for something like 3300 lb R. GAWR as opposed to 3800 R. GAWR most 3.5EB and 5.0 have.
My 6500 GVWR Truck has a 3300 R. GAWR but it has almost a 200 lb higher unladen rear axle weight than a Base 6010 GVWR. So I suspect even they both get the same weight springs the arch may be different.
