Yes. Your street manners will stay exactly the same, but you will enjoy a 47% lower low range. Going to 4.88 in the diffs will get you 37% lower in high and low range.

ya i like the thought of having
crawl box=L
300
F=H-N-L
R=H-N-L
plus i got some 2 in 2 out cutting brakes that'll be going in too so just out of the case's i'll have 5 options then add the cutting brakes that's 9 options i'll have of climbing obstacles ha ha
sad part is i've had all this stuff for over a yr now, just got tired of working on my junk and wanted to wheel.

D300 and a 4-1 kit for it. simple bolt in other then shifters (about 800-1500 depending on case price and shifter setup) giving you 4-1. this case is gear-gear case which is known for being a lot stronger then stock chain setup.
BOX4ROCKS kit, 231-D300 2.72 in front case, 2.62 in the rear. giving you 2.62-1, or 2.72-1, or 7.1-1 with both cases in low. Or you could put a 4-1 in the D300 and have, 2.72-1,4-1, and 10.88-1. (kit cost $600, plus case's, and low kit)
A low gear set like the Klune-V, a single reduction box that bolts between the stock case and trans giving you double low and the stock options. 4-1 ratio (all I have seen) said to be strong ($1200-$1300) Ratio options -2.72-1,4-1, and 10.88-1.
Stakk case, which has close to the same options as an atlas. It can be had new for 500-800 less, mostly because it hasn't been around very long and doesn't have the reputation the Atlas has... yet.. or will it?
Atlas case, Lots of options as far as shifters, and case gearing. Tried and true and known for being "bullet proof" and they knwo what its worth

2 speed gear box ratio options- Low Range: 2.0:1 or 3.0:1 or 3.8:1 or 4.3:1 or 5.0:1
4 speed gear box ratio options- Low Range: (2.0:1, 2.72:1, & 5.44:1) or (2.72:1, 3.0:1, & 8:16:1) or (2.72:1, 3.8:1, & 10.34:1) or (2.72:1, 4.3:1, & 11.70:1)
The Teraflex setup works, can't deny that. They allow you to use your stock drive-lines, shifters and crossmember. However they are known for being "burnt up" after driving at to high of a speed in 4 low. the guy at teraflex told Derek and I that " if the speedo is registering a speed it is to fast for the case and will over heat over a extended distance or time (said it could even happen in 10 mins) " cost $1200 new, or $750 for a "blemished kit"
This is Just some gathered info since the topic is up... I am undecided as to how I want to do mine.... I will probably end up with a 231 4-1 box in-front of my stock box giving me 2.72-1, 4-1, and 10.88-1, also 2wd low, and double 2wd low... The main season this is my thinking as I already have the 4-1 box, just need a planetary... (unless someone wants it, as this is a few years out for me lol)
