Anyone have the part number for the 5200 lb front coil spring? Just got a new Platinum cclb with the plow pack and it is a buckboard compared to the others I test drove. It was "used" with 28 miles, so too good a deal to pass up.

thanks for the help

 

Part number I found is

5C3Z-5310-EA

T code spring.

can anyone confirm if this is the softest 4wd diesel spring?

 

Subscribing. I am in the same boat, and would like to replace those springs.

And holy crap, at $110ea, is there a cheaper/better aftermarket alternative?

 

I have those springs in my garage, but I'm sure they would be expensive to ship from SoCal. You could always call up Eibach or any of the big spring manufacturers and see if they would spin you a coil.

 

For what its worth, I have a 17 CCSB F250 Platinum 6.2 and I am assuming this truck has the softest spring available in a 250. Part number 5C34-5310-AGD

 

I'm in a 2018 CCSB 250 6.7 that has the camper package on it and it has either the 5c34-5310-AGD or ADD springs. I am almost certain the D code is for a 5600 lb spring. I am looking for the lowest you can go too, but I think the answer is 5200 lb. I changed out the stock struts/shocks for Rancho's and the front end still rides extremely rough. I like a firm ride, but this is well beyond that.

 

 

Is your truck gas?

 

Thanks for confirming the part number. Just checking to be sure I get the lowest approved spring for the truck.

 

 

 

Have some new springs ordered. I'll update everyone when installed. I'll let you know on selling my springs.

 

Which Ranchos did you install?

 

 

RS9000XL's. They are a huge improvement over stock even with the firm springs. Setting 5 on the fronts gives the softest ride on rough pavement, but it feels too bouncy for my taste on the highway. Setting 6 on front gives a great highway/smooth pavement ride with little to no bounce, but is very rough on anything less than perfect pavement. I am wondering if the 5200 lb spring will soften the front end up just a bit and maybe then I can run on setting 6 and have the best ride on any kind of pavement.
