Question:

My 2008 Trailstar Q5SA trailer needs some new Dust Caps. Do you carry some that would work? I like the EZ grease type if possible. Thank You.

You will want to use a dial caliper or micrometer to measure the inner diameter of the hub you have on your trailer to determine what size cap would be needed. Check out the picture I attached that shows this measurement being taken on a hub.

I attached a link to all the grease caps we offer, once you know what size you need check out the link I attached to see all the sizes we offer.

If the dimension you find is 1.986 you'd want # 21-41-1, if you have a dimension of 2.441 you'd want the part # DC250L-DCRP, or if 2.717 you'd want # rg04-120.
