Gotcha, since they are electrical equipment then there is no way it's the ring and pinion manufacturer?GR2017 said:AC and Delco were GM's electrical equipment divisions. Not their transmission of gear divisions. I doubt GM has made their own gears for decades. They don't even make many of their own transmissions now.
Thanks for checking man!redtherocket said:ok
In big bold letters there is a number but I tried to use it to look up a set and I just keep getting some install kit from another brand..
You'll have to wait till I drain the rear end again... The code is etched on the ring gear, I noticed it this summer.
3.08 now so 3.73 will probably get me where I want for towingsilentbravo said:What is your current gear? Usually it is recommended to jump at least 2 ratios in either direction. So if you have 3.08 now, jumping to 3.73 (skipping 3.42s) would be good and should be quite noticeable.
With your 6 speed transmission, the 3.73 will be fine, even jumping up to 4.10 the overdrive RPM should only be around 200-400 RPM more with the 4.10, so it depends on what you favor more, performance or MPG
Check this thread out, Going to 33's, 3.73 or 4.10?
