Hey Ken, since your 2019 Keystone Bullet 248RKS has 3,500 lb axles the correct Roadmaster Comfort Ride kit you'd need would be the part # RM82MR actually. How's the ride quality on the Keystone currently?

OK, so I had already ordered the other system (which I now have to return), but I'm pretty sure that when I took the calipers out to measure the axle the trailer has 3" axle tubes and the one you said was correct is only 2 3/8" Did I measure that far out? And, actually, my trailer shop that was going to install the Roadmaster suspension called Roadmaster directly and that set that you have listed as 3,500 pound, according to Roadmaster is actually 5,000 pound and Roadmaster doesn't make a 3,500 pound suspension that fits my trailer. I just called my shop and confirmed.

@KenW Are you sure your axle diameter is 3 inches? It really does come down to the axle diameter to know which Comfort Ride System you need. The part # RM82MR is for 2-3/8 inch diameter axles but the leaf spring capacity is 5,000 lb like your shop noticed which is a little odd for sure. If the axles are 3 inches in diameter the correct part number you'd need instead is the # RM-2460-2560.
