If the hf2av uses 3 gears to drive the output shaft in high range, how does the underdrive kit work? (1 Viewer)

Hardly, when I say Limited Offroad, I don't live in Colorado and or Moab but when I go there I do off road the trails/mountain passes, hard to do with an LS/Alvalon.... Long drives pulling a trailer to get there from Oklahoma as well.
yeah, thats a terrible idea. search on here and you will find several members that had major issues with it.

Just talked to Chris. He said someone would have to call me back on the 3.3:1 pricing.That's where the phone comes in handy.
There you go. Bryce will be calling back.
I just tried calling you back and got a voicemail that isn't setup. I'll try again in a few minutes.
To achieve the 3.3:1 low range, you must do the high range underdrive and one of our low-range t-case gear options as shown in the gearing chart. As both the high range and low range are driven from the input gear (see the chart for the gear teeth count) you change your low range with a high range change as well. Hence how the 3.1:1 gears get 3.3:1 in the end. Clear as mud?

Definitely will call within the next two weeks. I think the 1.1:1 high (which when compared to 410s is equivalent of 456:1 ring and pinions - which is nice with 35” tires) and 3.3 low range is a very marketable combination. Saves the hassle of regearing front and rear ends plus gives a lower overall low range than one would achieve with ring and pinions alone. I’ll be in touch soon!

What is the additional step / work required for the hundred series?
The 100 requires a new input shaft and clip. We can provided the needed parts.
I'll get some pictures posted but Dave did some fantastic side by side gear mesh/pattern photos with the stock gears and the stock idler, stock gears and modified and our high range gears and the modified idler. In the end we both agreed the pattern with the stock ideler was better than the modified idler when using UD gears. Next up to try the modified idler with OD high range gears.
So, it's our opinion moving forward they the UD gears will be installed as they have for the last decade and as we've experience with all lower gear sets 4x-8x, some additional noise should be expected. Jury is out on the OD high range gears until we can mimic Dave's install meshing.
