TCBS-6 Twin  60" Center Bunk Supports ** 199.95
EXT-BB Tongue Extension to 15'-5" *** 139.95


** Option TCBS is used when you want extra center support because the boat would be transported  with gear loaded, or you have a RIB (rigid inflatable boat)  and you would like additional  center hull support - The Four supplied bunks will adjust to give proper hull support for a RIB and it is not required that you add the center bunks for a RIB, but some users may wish to add them. All Trailers have rear transom supports.


*** EXT-BB Tongue Extension to 15'-5" is a longer section of tongue that replaces one of the pre-packed tongue sections in the SUT-450-I package.  So you will have an extra tongue section left over, which is not returnable for credit.  However, if you ever wish to shorten the trailer, it can be easily adapted with this extra remaining piece.





  Bearing Protection System
  Included on Every Trailer

Sure Lube low pressure bearing lubrication system.  Protects bearings and prevents any seal damage. 
Easy to use. A Zerk Fitting is located under the axle's end cap. Removing the end cap allows you to use a
small grease gun to lubricate the bearings. 
The new grease pushes the old grease out. 




Optionally, this trailers may be delivered to your location fully assembled, depending on your area.  Please contact us for shipping quotes.
