Rear Axle Question

Hey All,
I am rebuilding my rear axle and saw that Snyder's offers a 3:1 ring and pinion set. Do any of you have an opinion on the high speed gears?
Thank You,

Good for a runabout w/good engine or a speedster - IMO ! Touring with an overhead, maybe.

Due to significant loss of transmission braking and significant loss of torque on hills, I would be a definite "NO" if I lived in a hilly area.

You need a strong motor to pull them, more than stock. If you are not planning to regularly run over 50, they are not needed.
Starting off with 3-1 only gearing is hard on the motor & low band.
I would not put them in a stock, non Rux rear end. Not friendly in a heavy/full touring or in hilly country even with a Rux.
Your braking is compromised. RM brakes are a good idea.
Given your limited description, don't do it. If you do, you will remove them & go back to stock in short order.

The stock 3.63 gear ration Ford used is generally considered an all around ratio for cruising and hill climbing. Yes you can run a little faster with higher ratio but you lose a little in hill climbing. For the average T driver the standard ratio is considered the best. MHO

I tried 3 to 1 gearing with a Ruckstell and returned to standard gearing in short order for all the reasons stated above.

I built a Ruckstell with 3:1 and wish I would not have. It is a Fronty speedster so able to pull with lots of power but way too fast. I do have outside brakes but it still takes some distance to stop. I am not pleased with the results and would never do it again. In a stock car I can't see anything except loss of power, longer time to get up to an uncomfortable speed and distance to stop compromised.
Other than that though...
