Replacement 6,000 lb Axle Leaf Springs for 2002 Keystone Cougar


I have a 2002 Keystone Cougar 29 feet long and a GVWR of 10,000 pounds. A few years ago I changed springs not knowing what the original springs were. I went by leaf thickness, length and stack number. I ended up with 2200 pound springs and they have flattened. My axles are 3inch diameter and Uinch Bolts are 1/2-20 X 7 inch so it looks like I should get either SP-218275 5000 pound or SP221275 6000 pound springs. These would be 2500 or 3000 pound springs. Which springs do you recommend. Ill be ordering Suspension kit K71-359-00 and APUBR-8 U-Bolt Kits. I have 8 new replacement bushings for the springs.


Expert Reply:

3 inch diameter axles typically are 6,000 lb axles so the part # SP-221275 that you referenced would be the correct spring for that capacity. About what lenght do you need? The part # SP-221275 is shorter at 25-1/8 inches or if you need a longer spring in this capacity you'd want the part # SP-053275.
