Ox Locker in GMT900 with 3.42 gears?

Yes, slightly higher RPM on the highway. Put it also put your cruising RPM where you engine is capable of making more power, so throttle response is better and the engine can maintain speed with less downshifting.

That will be nice. I have noticed that on the hwy hills.

Yeah, that guy with the snowplow truck had like 3.42 originally, then swapped a 4.10 rear end. So you just play around with different combinations of OD of tires for the front and the back with those 2 different gear ratios until your RPMs or speeds are close enough using those online calculators.

Like this one:

Spicer Transmission Ratio RPM Calculator

Use the Spicer Transmission Ratio RPM Calculator to determine your engine’s RPM based on the transmission gear ratio, tire height, MPH, and ring and pinion gear ratio.

Ahh. Thank you. That'll be very useful and will sear some figures into my mental tables. Added to favorites list.

What IS the effect on the highway, by the way? Just slightly higher RPM's, right? Going from 3.42 to 3.73.

a little bit yes, it's not really that noticeable but pulls better off the line

Yeah, that's what I'm most interested in. Better pull on hills around town and better towing torque.

What does that mean?

It means that if someone looks for the post in the original location, a link there will persist for 7 days, taking the user to the new location of the thread.
