bently, It does have spr and to the right of that it has 6F710 for a letter no. combo. is this the no you are speaking of? directly below the spr it has a letter combo of CCCC.

 

My truck is a 2006 F250 Supercap short bed. I changed the front springs to 5C3Z-5310-CA(6000 lb SPRING) and removed the factoryhelper spring from the rear. That madethe truck fit to ride in with the camper hooked up. Before on a concrete highway with the expansionjoints you seriously needed your seatbelt. Brand new truck with about 500 miles on the clock, towing the camperfrom Maryland to Sparta, IL on RT70 when we got to a smooth spot my wife said,we are selling this truck. Keep in mindI have owned nothing but Ford trucks for the past 40 years and have been towingthe whole time with my wife, first complaint. The spring changes did help, I still own the truck. Everything probably comes into play so I’ll tellyou about the whole rig.<o></o>

Camper is a 2004 Prowler, 26 foot. This is a heavy camper for its size GVW7,980, guessing from the drop in the truck when hooking up, tong weight over1,000lb. Hitch is a Reese WeightDistribution System w Shank - Trunnion Bar - 12,000 lbs GTW, 1,200 lbs TW and aReese Dual Cam High-Performance Sway Control.<o></o>

Truck actually rode quite well without using the weight barsbut sagged a little and swayed at highway speed. This past year, I added a Club Car gas golfcart to the mix, loaded in the truck bed. The ride is better than it ever has been.<o></o>

This link will take you to my original post on the ride andwhat was done to fix it as well as where I got the info on the spring weightratings. https://www.ford-trucks.com/forums/846305-front-spring-tag-from-a-06-6-0-f250.html Interesting that Ford cannot tell you theweight ratings of the springs. Well theycouldn’t at the time I was looking for the info and I am friends with a partsmanager.<o></o>

 

Mcrafty- the SPR is what I was referring to. What ever is under that tells what springs your truck has.

 

bently,

Thanks, I'll try and find out what the weight rating is with the code written there.

 

Thanks to all who commented on this thread, as always you never have too much information to make an informed decision.....I went ahead and had the 3300lb. rated spring installed today and it fit perfectly and the truck sits level with no load, the only exception was I had to use my old top 'helper spring so they had to replace the center bolt to get the block between the main spring and the helper re-bolted into one unit. I'll let everyone know if after I load the body the other spring sags and if I will end up replacing that side too. As of now I don't see that happening. I'll also add again that if you live out in the sticks like I do and need springs General Spring in Kansas city are very reasonable and the service is simply the best bar none.
