Rated 5 out of 5 by from Very supportive. These offer loads of support to the stock leather saddlebags! I was a little uneasy about applying glue to the inside of my leather, but used the EXACT adhesive Harley says to use in their instructions. It keeps the lid very flat & the support is impressive. All is well so far!

Rated 5 out of 5 by from Great for Keeping Bags Looking NEW They do what they say they do! They stop bags from sagging and keep them looking new. Easy install. I recommend adding the Keyed-to-Match Barrel Lock Kit P/N 90300010, makes it convenient.

When will Harley make a product like this available for the 2016 models?

This does not fit the 2016 Heritage Softail Classic. When will Harley make the kit for this bike?
Asked by: Loyal5

Can I get the installation instructions for the Flat Top and Lock Kit #88373-10A?

The link to instruction sheet J06058 does not work. I am particularly interested in the recommended adhesive for installing the flat tops. Thanks,
