Cub86 posted the question: Hi. I'm struggling to understand the lay down situation. I run on high bite damp smooth clay and think the conversation would help on my surface but from what I'm reading I need to buy the lay down kit tlr338004. And the dirt gear case tlr332063. But do I really need both from what I've read the dirt case is 1-2mm higher anyway and u don't use the +3mm hubs or the front pivot hrc or Hrc mod. So is the dirt lay down kit tlr332063 is all that's needed to get me a lay down set up that's suited for clay With the components and car I already have. And if I only get the dirt case is there any problems that will need to be addressed IE.. bone plunge . I do know I'll need 1mm spacers on the waterfall to clear the battery. Thanks guys really trying to get my head around this.

Franks response:
Laydown Conversion will work great by itself. You run the aluminum +3mm hubs, the diff is +3.5mm, and you run the HRC front setup. Just follow a setup sheet from tlracing.com (Frank Root).

Dirt Tranny has the diff at the same height as the standard tranny case, and works with the standard plastic hubs. Both are +/- 0mm from stock. When you run this, no need to run the HRC front mod either.

I've found the stock laydown conversion parts to work great for most tracks. The dirt tranny is a great tuning option, but definitely not 'required'.

Something I made, pretty basic. Just to give people an idea.

Has anyone tried the dirt lay down tranny with the 3mm hubs? It looks like it gives almost zero dog bone plunge, good or bad?

Do you need the entire diff, or just the housing? That link looks like it's just the housing only. (Edit: I misread your post, I see you are indeed only looking for the housing.)

If you can afford it get the serpent gear diff. The losi is for the RTR and it performs like it. Three .3 shims on either side.

Does anyone know what body is used in the 2nd photo of the Exotek lay down, on their website? I don't think it's a TLR body...?

Is the lay down transmission conversion good for all surfaces? My understanding is that you wouldn't want to run that in lower grip situations, correct?

It's designed for high grip conditions where you already have more rear grip than you know what to do with. If your on medium to low grip then stay stock

If running the dirt tranny I would stick with the standard hubs. I tried the dirt tranny yesterday at Norcal yesterday with good success. Really liked it!

For lower grip situations I would stick with either the 3 or 4 gear standup transmissions. The laydown works really good on medium bite with the right setup and on high bite it is amazing.

Is the laydown transmission internal gear ratio the same as the stand up ?

Idler gear size does not change the ratio on a 3 gear tranny. (Just an FYI when you freak out and see the size of that new gear!)
