Question:

Hi..getting ready to order kit K71-449-00 for my flat bed tandem axle trailer as all dimensions noted are accurate. Question re the wet bolts as my app has no zerks... just bolts and nuts and the hangar straps are only 3/16 wide vs 1/2 in the kit..will work? Also a few reviews noted easily stripped nuts on the bolts on the supplied ones...what Grade are they..and can I get upgraded wet bolts...tks

Hey Pete, yes all of the bolts that come with the Dexter Heavy Duty Suspension Hanger Kit part # K71-449-00 are wet bolts and have zerk fittings.

The shackles are wider at 1/2 inch which the bolts that come with this kit are long enough to accommodate. The bolts and nuts that come with this aren't designed to be really cranked down so they shouldn't get stripped.

Everything you need is included with this kit. Yes they have grease fittings. No worries, excellent quality; so much better than OEM.

The wet bolts are the way to stop squeaking in the spring shackles and lubricate reduces friction. However grease the bolts before tightening, as recommended.
