How low is to low???

[XJ4playin]

I currently run 33" LTB's with 3.55 gears. I bought a NVG241OR last year and I'm in the process of installing it. I stumbled onto a crylser 8.75 out of a 70' drag car, with 4.88's, a full spool, custom 35 spline moser axles. The only thing it needs is brakes and to be set-up for an XJ. So to my question.

1st - 2.80 (AW4) X 4 x 4.88 = 54
2nd - 1.8 x 4 x 4.88 = 35

Is this to low? I've heard if you have a crawl ratio higher than 50 with an auto there may be issues when trying to stop. My auto is controled, with swithches, I have no TCU - so I figured I could always switch it into 2nd if I need to. I may upgrade to 35's in the future but as of now plan to stay with 33's. Also will this low of a crawl ratio cause more breakage in the D30 (w/ a quick-lock)? Thoughts????

You may want to upgrade that rear to disks to help stop. The lower the gears, the more torque you're going to have on the driveline when trying to stop. Otherwise, 4.88 and 33s sounds good although I'm not sure what kind of locker options you'll have for that axle if you decide to get rid of the spool.

gears too low to stop?

that's what neutral is for!

stupid q here why is the AW4 a 4 multiplier in the final drive ratio?

4:1 t-case gearing; 2410 is a Rubie t-case... :wave:

138.9:1

I was confused at first by his notation but if you look again you'll see he has 2.80 as the AW4, and 4 as the rock-trac. But yes you definitely have a bad ass crawl ratio w/ that klune...buy me one too? :)

138:1 with Klune and t-case in low.

34.4:1 Klune in high, t-case in low.

51:1 Klune in high, case in low.

:doh:

Last line above to read; Klune in low, t-case in high........

However, crawl ratio is much more effective if the rig actually LEAVES the garage. :gag: :laugh3:
When we gonna try that thing out?
