Question:

I have a 2024 Voltage Vseries 3800. It does have tandem 7K Dexter axles. I would prefer to purchase new longer ubolts and nuts instead of reusing my old ones. Do you have a part number you can share?

Hey Brian, that's a great call. It is highly recommended to replace your U-bolts after you take them off for any reason. The nuts are only meant to be torqued down once.

The longest U-bolts we have for a 3" diameter 7,000 lbs axle are the Redline item # APUBR-9. They measure 7-1/16" and you'll need one set per axle.

I saw you were looking at the Roadmaster Comfort Ride Leaf Spring Suspension Kit item # RM-2460-2570. Is this why you are needing new U-bolts?
