Why the hate on Dynatrak ProFloat60?

[FreedomFur]

I had the misfortune of hitting a pot hole on a trail and bending a brand new 2022 Rubicon Dana 44 with KO2 37” tires on it (2 months into ownership). I am using the insurance money to put on a Dynatrak ProRock 44 and have been looking for a quality 5 bolt axle in the rear for a future project since I am now super skeptical of the Dana 44 strength.

Dynatrak’s ProFloat XD60 gets a ton of hate on [Banned Site]. But for someone like me who doesn’t plan to anything larger than a 37” or 38” tire, this seems like a great option. The only other thing out there I could find in a 5 bolt pattern was the Currie axle. I would much prefer a full float, but don’t really want to go to an 8 lug right now. The ProFloat is rated to 40“ tires.

This isn’t a “now” project. The cost of axles is RIDICULOUS. At the end of 2019 you could buy a Dana UD60 for just over $5k and now they are almost $10k!

No thoughts from the forum?

Maybe ask over there why they don't like it. ?‍

Not a member on their forum. They are not a fan of the semi-float design especially on 40s. Wondering if anyone here has direct experience now that this has been out for a few years.

Full float is far easier to trail fix...so that's likely the reason.

What's the cost difference?

Generally speaking, full-float is stronger than semi-float, all else being equal.

Some groups of people get overly focused on those kinds of details.

If I went full float I would have to get Dynatrak to build it with a 5 vs 8 lug. I would be its about $10K. Haven’t seen a price yet on their ProFloat, but Currie’s similar model is $6K.

A full float 5 lug will still require a wheel change because the hub is big and it sticks out through the center of the wheel. Also, it's likely to have at least a 5x5½" bolt pattern where the JL has a 5x5" pattern. There's no huge benefit to running a 5 lug pattern

Ugh. Makes me wonder if I just run as is, and then in a few years make the full switch to Dana 60 8 lug, front and year, and sell off the ProRock44 and rear Dana 44 at that time (versus keeping the ProRock 44).

Hi,

Full float if you break a axle the wheels are still attached, a semi-float like our current 44's if a axle breaks it can slide out or if it breaks at the flange will no longer be attached and a pain to drag off a trail.

Jim

I had a early D44 full with a Detriot locker. There was a lot of slop to take up to start moving and you could really feel it with a manual trans. Rear manual hubs were nice for flat towing, which I did a lot.

I know someone who has been running the pro-float for the JL for over 2 years. all on 40's and running King of Hammer trails, zero issues. I'm running a semi-float 60 from fusion, working fine so far, the 40 spline axle shafts made me confident about running it.

Thats on the earlier TJ, etc, it's all bolted into the axle so now they're not going to slide out. Breaking at the flange could happen but not likely, what will happen is it will bend.

Is Dynatrac a sponsor over there? Back in the days of JK Forum, that was usually the deciding factor as to whether or not something was panned or praised.

The ProFloat really minimizes the issue had with both JK and JL/JT rear axles- bent wheel hubs. The JK/JL/JT all have a wheel bearing that is significantly further inboard than the previous TJ Jeeps. I can't really remember seeing a TJ with a bent axle flange. The deeper wheel bearing allows more leverage on the flange and is the reason (along with weight) so many JK/JL/JT failures are seen.
The Dynatrac ProFloat axle addresses these issues.
No question, a full float design is superior to a semi-float design, but, it's not always needed. A bloated JL/JT on 40's should have a full float but if you stay under 6K# this should be a great option.
