Frequently Asked Questions
Q: What does idler mean for this hub kit? A: An idler hub carries the wheel on an axle position without a brake assembly, so it spins freely rather than braking.
Q: How do I confirm this hub fits my trailer? A: Check your axle rating, bolt pattern, and stud thread size. This kit is for 3500 lbs axles with a 5 on 4.5 pattern and 1/2"-20 threads.
This is an aftermarket replacement part. Confirm fitment before purchase.
