well today i got some work on my drivetrain.. got my gears checked there 4.10's in my 4X4.. and i got a 10.5" 14 botl rear end with the 205 transfer case and 8.5" in the front end.. does this sound like a strong set up?? how much horse u think my rear end will hold for power?? i hear all this talk about ford 9" all the time.. but mines a 10.5" doesn't this mean mine is much stronger? sorry for dumb questions... i just aint familiar with rear ends.. but learning! thanx

14 bolt full floaters are tripple mega strong, just really heavy. It is a perfect rear end for a big 4X4. The pinion stays a lot larger when you start going real low in gear ratio.

If you already have the 14 bolt, then just keep that. You won't be breaking it unless you have like 600 horsepower and 44" tires. I wouldn't even worry about axle shafts unless you break one. You may need a locker, or limited slip. Your gears are just perfect for a truck that has a V8. With V8 torque you don't need anything any lower. Also 4.10 gears are very strong due to their pinion to ring gear size.

If it is an open diff, you can get a Detroit Locker to drop into the stock carrier for around $300. The Gov-Loc factory limited slip is marginal in High HP/Big tire applications. There aren't many other traction aid options at this time. A company in Germany is working on a selectable locker for them. They are saying they should be available soon.

They are easy to convert to rear disc brakes, too. That helps reduce the weight of the unit.
