Stinger Gear Box

Post by Dan Coffey »

I have a Stinger 2.38 to 1 box and am thinking about going to a 2.68 to 1.
Can I have the gears changed and if so is it worth it? Or do I just sell my box and get another.

I have been told that the housing is to small to go to 2.68 from 2.38. If your box is in great shape you would proly be better off selling it for maybe 2200, and buying a new one. Im having a stinger rebuilt right now and was ruff quoted 1300 if it needed new gears. A new 2.68 soft drive stinger would be just under 3100 tyd. I also know were a 2.68 balistic is that is a demo with less than 10 hours for 2900

I had a 2.09 to 1 that had 317hours and running strong. Sold it and bought a used 2.38 and got an hour out of it. 3 bad bearings. You may be able to go 2.55 but im not sure. The say boxes should be good for 1300-1500 hours if maintained but ive heard of alot more hours than that

The whole housing thing has me baffled. When you go from one gear ratio to the other you are taking one tooth off the drive gear and putting it on the pinion gear. Gear diameter changes but shaft centerlines remain the same. Example, 2.38 ratio is a 49 tooth drive gear and 21 tooth pinion. Going to a 2.68 requires a 51 tooth drove gear and 19 tooth pinion. Gear diameter on both change slightly, but not enough to require a new or different size housing. In an effort to clear the muddy water, we can run any gear from 1.8 through 2.9 in the same housing, and our housing is slightly smaller than a Stinger. Theirs holds 32oz gear oil and ours is 24oz for proper oiling. I would assume you could swap gear ratios and the housing won't be an issue.

That said, it's certainly easier to sell a new box than rebuild an existing box and more profit on new vs rebuild.

I was also questioning the gear box size thing!!! Counld not see why it would not fit.

If the shaft centerlines are the same, and I bet they are, gears SHOULD fit but dunno?!
