Mark,
There is a 2.72 rear end gear that fits the Tiger differential. It has a 26
(fine) spline pinion gear, instead of the 10 (coarse) spline pinion gear. I
have a couple of them.

Speaking of gear ratios, has anyone ever found a Dana 44/Salisbury rear
end ratio LOWER than the 2.88:1 ratio in our stock differentials? I
searched the web and found ratios as high as 5.89:1 (imagine, a top
speed of 74 MPH at 6000 RPM, but would you get there fast!). Assuming
you convert your Toploader to the wide ratio (2.78 1st) gear set,
dropping to a 2.66:1 rear gear set would still give you a better launch
off the line yet drop your 4th gear cruising RPM about 300 rpm, so for a
205/50R15 tire, you would be doing 2700 RPM instead of the 3000 RPM with
the stock 2.88:1 ratio.
Why ask this, you say? Well, my stroker motors push out over 400 ft-lbs,
and the five speed T5s that fit inside the Tiger tunnel are not capable
of handling that level of torque unlike our faithful Toploader. Plus
with that amount of low end grunt the car will launch off the line hard
in pretty much any gear you choose.
Any thoughts?
