Hi - I have a 65 c30 that I converted over to a 14 bolt dually rear axle. I have two tension/retaining rings (1st and 2nd pics) that I assume go on the rear axle to allow for the conical style lug nuts to seat properly. However for the front end (3rd pic) - I did a late model 1ton (I think that's what it was) squarebody swap - do I need the tension ring to properly mount the front wheels, or do I just go with a "flat" style lug nut, if there is such a thing? It's been quite a while since I did the front and rear swaps (other projects creeping in) and I can't remember (getting old :) ) how the wheels were originally installed, the front end didn't come with any wheels installed. I've located information regarding the rear tension ring, but can't find much about the front.

Thanks in advance for any guidance!

The squares I've had/worked on an my 99 dually all used the ring and conical nuts for steel wheels. Aluminum wheels (like alcoas) usually get the lugs with the integrated washer.

I think it all depends on if the wheels are hub or lug centric maybe. Im pretty sure There's some variables. I've done unsafe things with wheels and learned to do the research like your doing.

My old '84 and '93 K30's were both 6 tire one ton's and had the style wheel you've pictured front and rear & used the ring. The '93 has 14mm studs and lug nuts that are set up for hub caps.

Gotcha - sounds like I need to round up another set of rings for the front. Thanks for the information!
