  • Hello, I see that these are out of stock - when will they be back in and when they are is there a bulk purchase discount available?

    Sorry, but we should have them hopefully by the end of next week, or at the latest by the beginning the week of October 12th. And yes, we'd be pleased to offer a multiple item discount. Please contact us by email with your needs and we can offer you a unique coupon code for the larger quantity.

  • Is the 70 pound capacity limit for one of the wheels or for a set of four wheels?

    The limit specification is per wheel assembly, where each wheel assembly uses 4 individual wheels. A full set of 4 includes 16 total wheels and has a weight limit of 280 pounds total.
