Do You Have a Disc Brake Set for a Boat Trailer w/ a 5 on 4-/3/4 Lug Pattern?
Updated 10/27/2025 | Published 03/15/2025
Question:
Hi, I currently have a 24 saltwater boat and trailer with tandem surge drum brakes. Total weight less than 6,000. They are full of rust and corrosion, and I would like to upgrade to disc surge. Size is 4 3/4 x 5. I can use the Dexter actuator, but can only find 4 1/2 x 5 disc sets listed. You you have a set of this size? Thank you

Hey Chris! Sorry but we do not have a disc brake set up that has a 5 on 4-/3/4 lug pattern. The only solution I have for you is to install the 5 on 4-1/2 Dexter Premier Disc Brake Kit item # T2HRCM10DAC. These will work with your Dexter actuator but you're going to have to swap out your wheels. They're sold per axle so you'll need two sets.
I have linked our entire selection of 5 on 4-1/2 wheel and tire combos below. So you can see what your options are depending on your tire size.
If you have any additional questions feel free to add them to the comment box below and I'll be happy to help you.
