I use the track holders on my x deck no issues . From what I understand there was a change on the 2017+ x decks to strengthen the back tube for track holders and extensions . Dont forget to remove track holder before unloading . Buddy did that lol
Re: First Time Sled Deck-> What to look for?
They are decent for the price . You can get them at wholesale liquidators FYI . Need to ask for them they aren't on the floor
