OK im new to toyotas and gearing. I am putting a 5.3 chevrolet in my 93 v6 4runner. It has stock 4.88 gears which are way too low. I need something in the 3.73 range. Can this be done with out changing the axles?

 

You need a new rear 3rd member. The stock 4.88's come in a "special" 3rd member and you cant swap other gears. I had the same dilemma as you and I just bought a new rear 3rd. You'll definetly need a V6 3rd to handle the power of the V8, a 4cyl 3rd will swap in, but it's too weak for the V8 power. Also, go to pirate4x4 and look at the classifieds...there's always tons of 3rds for sale.

 

so what 3rd can i use and does anyone even make 3.73 gears for these things?

 

You'll need a Toyota 8" V6 3rd. Lowest gears made I believe are 3.90's, but dont quote me on that.
