2 part 742 Question re Ratio & Suregrip

cudamark said
It should be the other way around....one turn of the wheel and just short of 4 revolutions of the driveshaft for a 3.91 ratio and a sure grip. If you're just jacking up one side on a non-sure grip, count the driveshaft revolutions and double it. You can add a sure grip unit to your existing gears but if you don't like that ratio, why not get a complete sure grip 3rd member with the gears you want? It's not a real difficult job to install a suregrip to your gears but it does have to be done right. I think I remember there being a few threads on this subject so you might want to run a search.

Thanks for the reply cudamark. I had both wheels off the ground (being an open diff they spun in opposite directions.), and triple checked. Got 1 turn on the driveshaft for every 4 turns of the wheel. :scratch:

The ratio seems OK for me, just trying to determine exactly what the ratio is. Will ultimately come down to $$$ and difficulty level when tackling the Suregrip, i.e. swap used Suregrip 3rd member vs buying and installing an aftermark "posi" unit.

Have a good one,
Pat
