Mitchell and 4.11

) and I plan to install a Mitchell OD. Does anyone have any experience with either the 26% or 36% with a 4.11 final drive? I guess I could convert the final drive ratio if that makes more sense.oldredford

It would be the same thing with a 26% reduction on a stock 3.78 works fine for me. The 4.11 with a 36% reduction would be great in the mountains I would think and then you can have your 36% for flatland.

BigErn,
I have had a 4:11 with a 26% Mitchell in my driver (Phaeton) for over 80,000 miles. This combination has worked well for me over flatland and mountain passes. This past spring, I lost 2 teeth on the pinion and ordered a new 4:11 gear set to replace it. I did not even consider a different ratio. I have a 5.9 Brumfield head and a counter weighted crankshaft, so I have a little extra power and ability to rev to pull the car in and out of overdrive. With this combination, I have no trouble keeping up with the slow lane traffic on an interstate. I wouldn't - didn't change a thing. I would not go with the 36% unless you have the power to pull it and then also the desire to move that fast. I typically use overdrive as a 4th gear meaning I get up to speed and then put it in overdrive. When I come to a hill, I will drop out of overdrive and climb it. With the syncro in the overdrive, it is easy to shift up and down on the move. JMO
Good Day!

I run a Columbia which is 26%, and 4.11's, and I wouldn't change it. With the 36% you would be lugging the engine, not good!
