Do you have a question about this Accessories and Part?

  • Can a Fold-Away Trailer Tongue Hinge Kit Work with Hydraulic Surge Brakes
  • You can use a fold-away hinge kit with a surge coupler but you will need to replace the hard brake line with a flexible hose like # T0777300 that you have referenced. For fold-away drum brake applications use # T4839000. For a 3 x 4 inch tongue use 2 adapters # T4842100. For disc brakes use # T4839100 and 1 of the adapters. You would still need flexible brake line with either of these couplers.

  • Availability of a 2 to 3 Foot Fold-Away Trailer Coupler Hinge with Attached Coupler
  • If you are needed a coupler and tongue that is already attached to a fold away hinge, we have # T4839000 for hydraulic drum brakes or # T4839100 for hydraulic disc brakes. These couplers will fit a 3x3 tongue using 2 of the spacer # T4842100. The pivot length is 21-1/2 inches long. But if you are looking for a 2 to 3 foot extension to the tongue you have, you will need to have a qualified welder in a machine shop of shop that works on trailers fabricate an extension for you.

  • Will Titan Aero 7500 Swing-Away Actuator # T4839100 Fit a Mastercraft Boat Trailer
  • I went out to the warehouse to measure the spacing and bolt/pin diameter on the Titan Aero 7500 Swing-Away Actuator # T4839100. The distance between the pin and the pivot bolt is 3-1/4 inches on center. The pin/bolt diameter is 3/4 inches. I could not say if this is a direct replacement for the one on your Mastercraft trailer so you would need to go by the measurements. This coupler can be used for a 3 x 5 inch tongue as is. If you have a 3 x 4 inch tongue you would need a spacer...

  • What Size Trailer Tongue Fits the Aero 7500 Coupler in Titan Disc Brake Kit, # T4843400
  • I spoke with my contact at Titan and the Aero 7500 Coupler included with the Titan Disc Brake Kit, # T4843400, is designed to fit on a 3 x 5 inch tongue. But, it will also fit on a 3 x 3 inch tongue or a 3 x 4 inch tongue if you were to use Titan Adapter Kit for Swing-Away Brake Actuators, # T4842100. This is a 1 inch spacer so for a 3 x 3 inch tongue you would need a total of 2 and for a 3 x 4 inch tongue you would need just 1.

  • Swing Away Surge Brake Coupler Recommendation for 2 inch Ball 7.5k Capacity
  • The Titan Swing Away Surge Actuator part # T4839300 would be what you would need. This actuator has a 7.5k capacity, can fit a 2 inch ball, and can fit a 3x4 inch trailer tongue. Since you have a 3 by 4 inch tongue you would also need the spacer part # T4842100.

  • Hinge and Bolt Hole Spacing on Titan Aero 7500 Swing-Away Actuator # T4839300
  • The Titan Aero 7500 Swing-Away Actuator # T4839300 has, according to my technical contact there, a 5-inch inside height at the folding coupler. Please see the linked photo. The spacing of the fixed bolt and pull pin holes, measured center to center, is 3-1/2-inches. This coupler can be used on trailer tongues that are only 3- or 4-inches tall through the use of spacer block # T4842100.
