Our boat trail­er bunk slicks are fre­quent­ly cho­sen by Ama­zon as ‘Ama­zon’s Choice’ for their high per­for­mance and cus­tomer sat­is­fac­tion. View on Ama­zon or Learn More…

About Us

Boat Trailer Spares USA; An Ultra High LLC Company.

Boat Trail­er Spares are a lead­ing sup­pli­er and man­u­fac­tur­er of pre­mi­um boat trail­er bunks pro­duced out of sol­id plas­tic for the marine boat trail­er industry. 

After a long and suc­cess­ful his­to­ry span­ning over 30 years of pro­duc­ing and sup­ply­ing the Aus­tralian marine indus­try with our pro­pri­etary plas­tic pro­files and boat trail­er keel rollers; we have now intro­duced these prod­ucts to the US mar­ket! Our boat trail­er parts in Aus­tralia are the indus­try stan­dard when it comes to reli­a­bil­i­ty, per­for­mance and sim­ple to use boat trail­er bunks, slicks, keel rollers & accessories.

Pre­vi­ous­ly, only known to US con­sumers are tim­ber and car­pet style bunks. Car­pet bunks do not work, they need con­stant replac­ing, and sim­ply do not work like they should. Our aim is to change the way boat users launch and retrieve their boats!

Plas­tic bunks and pro­files elim­i­nate all the issues car­pet bunks give users.

For all boat trail­er bunks and keel roller ques­tions, sim­ply con­tact us via our help desk, and one of our expe­ri­enced staff mem­bers will assist to your needs. With our head office locat­ed in Dal­las, Texas we offer our prod­ucts USA wide.
