Question:

Hello, I am looking at what all is included in the replacement MQ3 For adventure Cargo box. I see the few pieces that I need and was wondering if you guys sold pieces from that set individually? Thank you.

Thanks for reaching out John,

Unfortunately, we aren't able to sell the individual pieces from the Replacement QM3 Quick-Mount Hardware Kit # TH04997 separately. The hardware is only available as a complete replacement kit.

Which piece are you needing to replace?

Like many, I didn’t need all the new replacement parts included in the etrailer kit, but for a little over $100, my more than 20-year old Thule Frontier cargo box was returned to new. Every new new replacement part was a perfect fit and the peace of mind that comes with having the box fully secured is worth it. I may not be good for another 20 years, but my Thule Frontier is. ??

@BillA Thank you for sharing! It's great to know the kit restored your Thule Frontier back to new. Yes, the kit may include more parts than some may need, but that way you have extras incase you need them. Thanks for stopping by and we appreciate you choosing etrailer!

Hey James, it would be that top left piece with a hook on it, two longer silver screws, one of the 4 brackets in the top middle. Pretty much I have a storage rack and have all 3 other clamps to mount to the roof rack but am missing the 4th set of clamps. These pieces here look exactly like what I have, but I only need one set.

@John got it, we get these in as kits pre-packaged from the manufacturer so we have to offer the kits complete. I know you don't need the extra parts but if you order the kit at least you'll have them in case for the future.
