    Axils replaced

    I upgraded the axils on a 20 year old trailer from 3500# to 7000 # . The axils were under sized from the beginning and we were always pushing the limit. When I replaced the old ones, one had a broken spring and there were several shackles about to wear through. Everything went together very good and it was a great upgrade.

    Axle review

    Axles are great! Went to put on u bolts and found one u bolt plate was wrong and had to drill out holes. Also 5 out of 8 u bolt nuts were the wrong size but luckily I found the correct size in my bolt drawer. The two issues did set me back an additional hour. All in all it is a great kit.

    Hi Chad,

    Thank you for the 5-star review and for taking the time to share your feedback on the 7000 lb Heavy Duty Tandem Axle TK Trailer Kit. We're glad to hear that the axles are great and that overall you're satisfied with the kit quality. We sincerely apologize that one of the u bolt plates was incorrect and required drilling out the holes, and that 5 of the 8 u bolt nuts were the wrong size. We understand how frustrating it must have been to have that extra hour of work when you were expecting everything to fit properly. We'll definitely take this feedback to our quality control team to help improve our inspection process before these kits are shipped out. We appreciate you mentioning that it's still a great kit despite these issues - that helps us know we're on the right track with the overall product quality.
