You have a 2wd so the ratio doesn’t matter a bunch, 3.73 is the most common. I changed all the internals of my 98 with these parts. They really didnt change em much throughout the years. Make sure you get 2 sets of new pinion bearings (1 set, inner races bored out to slide on and off easy for test fits, and 1 set for the actual final fit.) take your time and be very thorough. Look up EricTheCarGuy on youtube, he does an excellent video of exactly what you’re doing. Hope this helps. **Q: Tengo una Chevrolet Silverado Ltz 4x4 z71 2014 5.3 tengo rines 37x13.50x26 me sirbe o cual me recomiendan** A: for a 38" tire, id recommend 4.88 gears **Q: what ring and pinion do I need for a 57 Chevy 3.08 gears?** A: You need to know what rear or front end you have.
