Can I Upgrade My Axle and Keep the Beam and Spindles?
Updated 10/15/2024 | Published 10/13/2024
Question:
I want to upgrade my 5th wheel suspension and I have a few questions: 5th wheel is 2019 Keystone Cougar 29RKS 10,400 lb GVWR. Weve probably got about 20,000 miles on it. The axles from the factory are rated at 4400 lbs. I want to upgrade to 5200 lb axles and springs. Can I keep the original axle beams and spindles, and replace everything else? hubs, brakes, springs, etc. Nothing is currently bent or broken, but the tire clearance is pretty low and there is occasional tire rub on the undercarriage on all tires.

Expert Reply:
No, you would definitely need to upgrade the entire axle, to include the axle beam and spindles, not just all of the other components to get a 5,200 lbs axle.
If you could send me a measurement of your Hub-face-to-hub-face length and your spring-center-to-spring-center length I would be happy to see if we have a replacement 5,200 lbs axle that will work with your Keystone Cougar 5th wheel trailer.

The label on the axle beam has "HF = 85" and "SC = 68.5" I think those are the numbers you are looking for? The trailer is in storage so I can't physically make the measurements right now.
