How To Connect Yakima MightyMounts To Yakima HullyRollers

Updated 02/03/2026 | Published 07/24/2024

Question:

Yes I have a 3 1/2 bar on my ladder racks for my truck, I thought this would fit, but I have the Hully rollers olders set that has the 4 bolt hole square bracket, I see some people say it works, and some said a old bolt package thats no longer carried, how do I get the rollers and v pads, also 4 bolt pattern like 4035 to fit on the 3590, help

Hey Kevin,

The Universal MightyMounts # Y03590 would connect to the HullyRollers using the included carriage bolt running down through one of the two bolt holes on the roller brackets on each side. I'd offset the mounts on each roller for more stability. I've attached a picture below someone sent in showing both of these components working together to mount onto their roof rack.

Hey Kevin, how did things go getting your HullyRollers and V‑pads to work with the Universal MightyMounts on your ladder rack? Your update could make it easier for others trying the same setup.
