Question:
Hi, my name is Nicholas and I own C3 Mobile Rv LLC in tucson az. I have a client who wants us to install the roadmaster comfort ride system pn: RM49NQ. We are looking to aquire a part number for the longer Ubolt kit. The customer has tandem 6k axles. I have a picture of the axle tag as well, I just cant attach that here. Any information would be greatly appreciated. Thank you!

Expert Reply:
Hey Nicholas! You're referring to the Roadmaster 2630 for 3" axles from the installation instructions. Although we don't have the Roadmaster part, you can use the Dexter 3" Round Trailer U-Bolts (Qty 2) # SP01-060. We have confirmed with Roadmaster that these are 7" long U-bolts so the Dexter will work as well.

Easy install. I'm 70 and installed by myself, did passenger side one day (4 hours) and did driver side next day (4 hours). Rides well no porposing, smooth ride. We triple tow in AZ, rides great.
