Changing the gears in my suburban
I have decided to change the gears in my suburban (2008 5.3L 4sp auto), but not sure how much of a change to make. I currently have 3.73 gears, and was thinking 4.30 because 4.10 doesn't change much,...

intheburbs,
Are you saying the SF 9.5" RA in my 8 lug GM C2500 is not worth having? or its going to blow up on me? I've had more issues with GM's POS auto transmissions than I have the SF9.5 RA's I've had. 30K blowup and get a rebuild auto trans like clockwork.......The one in my C2500 is the first TH400/4l80E derivative I've had with more than 40K miles. Actually has over 100K which is unbelievable in my book!
With this said, the GM RA's in the 15 series rigs with 5 or 6 lugs, do not do well when subjected to heat via towing or equal, generally speaking. So upgrading trucks, getting an aftermarket cover that hold more oil, has fins for better cooling as mentioned is probably a good idea!
