Dana 20 VS Dana 300

When I bought my 79 cj-7 it camed with two transfer cases, one in it, and a spare(don't ask, there were pieces everywhere). When I finally got a chance to look at them I realized that ones a Dana model 20, and the other's a Dana 300. Which one do I keep and beef up? or are neither that spectacular when it comes to heavy off-roading?
thanx

The 300 is a very strong design, IMO stronger than the 20. Just as an example of this, many of the Jeeps at the ARCA meet this past weekend in Farmington were running 300s with TeraLo kits, I don't believe there was one broken case. The other part of this whole thing is the much lower low range in the 300, 2.62 as opposed to 2.03. Keep the 300.

<font color=purple> The 300 will need an adapter to work with your tranny, but I agree that it's the better unit - mainly 'cause of the lower gears. Rather than an adapter though, you should consider a different tranny if you want to use the 300. Odds are, you have a 3-speed. The 20 has a better U-joint yoke (u-bolts instead of straps). Make use of that on your 300 if you decide to put it in. </font color=purple>

I got bash on this page once when i posted saying i like the dana 20 over the 300 since i didn't like the looks of the aluminum output covers on the 300 . But when it comes down to it, they are both strong, the dana 20 was used for a long time so they are more redillay available. If you put ennought power to either they'l break. The 300 has the option af a dul stick shifter. I'v heard many horror stories about the teralow gear kts breaking but not latley so mabey they fixed them. Personally i say use whichever one will bolt to the tranny since an adapor runs around $400. They are oth decent and i run the dana 2 now but truthfully on my next jeep i'm running a np-205. Or is t the np-203? I get them mixed up, whichever one is the part time case is the one i'm running. I think my brain's on vacation.

I'm gonna side with Al on this. I'm cheap, use whichever one bolts up to your tranny. Thats probably the D20. Overall, if it was a direct bolt in the D300 is the better case. But I think the D20 is a decent case, its cast iron case and gear driven. True the low range isn't too hot, 2.03, but overall its pretty stout. Another consideration is, I think it sits up higher in the frame and doesnt hang down as low as the D300. Considering the price of an adapter, the Tera Low Dana 20 kit may be an option($695) somewhere down the road (3:15 low range). I'm gonna do that eventually, but...

<font color=purple> Yeah, I'd have to agree that cheap & easy is normally the way I'd go. BTW, it's the 205 that is the gear-driven part-time T-case. The 203 is the chain-driven full-time unit. </font color=purple>
