Roadmaster Comfort Ride Leaf Spring Suspension Kit for CrossRoads Elevation TF3612  

Updated 07/27/2025 | Published 05/01/2025

Question:

Hello, I own a Crossroads Elevation TF3612-13 Serial 4V0FC3623DE012086 Lippert 7000 LB axles Is this upgrade what I need to replace the original suspension? If so I would want to replace the dry bolts with wet bolt could you supply the correct wet bolt specs and/or part number. Thanks

Hello again Adam! Since you have 7k Lippert axles the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 is the correct kit. This is going to be a significant improvement over the stock suspension. For wet bolts you can use the # 34007-187-00. With the way the system works you will only need four wet bolts for this setup. Let me know if you need anything else!

Thanks again Robin! While I'm thinking about the suspension, let's talk about replacing the axle bearings. What parts am I going to need? Do you need the specs on the axle and hubs or can you find that information from the model and serial number I provided.

@Adam since you gave me the serial number I can get that from Lippert. I'll have to wait for them to wake up then I'll get back to you.

@Adam sorry for the delay here, I ended up taking my wife to the ER (she is fine) and then I was off work so I didn't get that from Lippert until today. I will need the actual serial number off of the axle, what you gave me was the VIN which can't be used for axle identification.
