Hey Hector, thanks for all the info! I got those numbers over to Dexter, and they were able to tell me that this is a 2,800 lb axle with a 83.75" hub face center to center, 66.75" spring seat center to center and is underslung.

If there is something you were looking for in particular to this axle, please feel free to let me know!

So both axles can handle 5,600 lbs? I just have the frame of the Rv I was thinking of putting a 500 gallon smoker on it with a 40” x 4 ft long square fire box

@HectorA Hector, each axle can handle 2,800 lbs so yes both combined can handle up to 5,600 lbs.

Would you recommend to upgrade leaf springs?

@HectorA It looks like a 500 gallon smoker can weigh anywhere from 1,950 lbs up to 2,800 lbs, so upgrading the leaves wouldn't be necessary since it'd be well within your capacities.

@HectorA You're welcome! We actually just bought my Dad a smoker for his birthday, so I'm definitely looking forward to eating all of the smoked meats in the future! I hope you enjoy yours!
