Regeared my 3RZ.

Just thought I'd post this here for anyone thinking about a regear.

My truck had a 3RZ with a 4.10 rear end so I regeared up to 4.30 using the third out of another truck. Easy as pie. Remove the axles, unbolt the third swap the new one in. I didn't do any shimming since both rears were set up and I just swapped housings. Man did that little bit help. Acceleration's improved. Pullings improved. Gas mileage has even improved around the city. That's with 31x10.5 Goodyear Wranglers.

 

I have driven my friends truck same exact as mine 2.7 5 speed with 31x10.5's but 4.10. Mines 4.30 it's quite a difference. My teacher in Transmission class always said if you want good power cheap gear it.

 

I am guessing that you have a 2wd, right? lol.

 

Yes. The one and only 1995-1997 6lug 2wd.
