Hello Pat. The Replacement Trailer Hub Wheel Stud #RG03-080 has a .545" knurl diameter. The distance from the cap to the threads is 1-3/16".

Trailer couplers are not rated for tongue weight capacity. They are rated for Gross trailer weight, as long as the gross trailer weight is within the capacity of the coupler, the coupler is installed properly and the trailer is designed properly,…

We do have a very similar replacement coupler that is rated for 21,000 GVWR, and it is the Titan Bolt-On Coupler #T4855300. The angle that your photo was taken I can not tell if it is a 2 or 3 hole adjustable coupler, but this Titan part is a 3…

Yes, the Sleeve-Lock Trailer Coupler #CTA-196 will fit the channel bracket that comes with the Brophy Lunette Ring w/ 3-Position Adjustable Channel Bracket #BR43ZR. The bolt holes match as well when it comes to size and spacing so you'll be good…

Hello David. All of the 2-1/4" or 2-1/2" long 9/16" wheel studs we offer have a knurl diameter of .68, such at the Kodiak Wheel Bolt #K916WB25. We do not have anything with a knurl size of .60 or .62. We do have some 1/2" studs…

You can convert surge brakes to an electric over hydraulic braking system. To do this, you will need an electric over hydraulic actuator and a brake controller. For an electric over hydraulic actuator, I recommend looking at the Carlisle HydraStar…

Thanks for reaching out, David! We do have replacement top plates, like the U-Bolt Plate #TRTP238175 for a 2-3/8" diameter axle, or the U-Bolt Plate #TRU69FR for a 3" diameter axle. We also have a selection of 26" long leaf springs…

Instead of using the Hydraulic Brake Kit #AKFBBRK-35-D which requires using 14"-16" wheels you should use the Dexter Galphorite Free-Backing Hydraulic Trailer Brake Assembly Right #T4423400 and Left #T4423500. These will fit with your…
