04BlackSSS2 Posted January 17, 2008 Report Share Posted January 17, 2008 i wanted to change out my gears to 3.73s or 4.10s in my 2004 rcsb with a 5.3, 4 speed auto. i was wondering what RPM you were hiting at a crusing speed of like 60mph. i know that the 4.10s will jump off the line but not top out at much.

Depends on what you mean by "top out". My TBSS has been to 151 mph (GPS) in 3rd gear without hitting the limiter. It has 4.10s Quote Link to comment Share on other sites More sharing options...
zippy Posted January 17, 2008 Report Share Posted January 17, 2008 What tire size are you running is very important in this choice. Quote Link to comment Share on other sites More sharing options...
00silverad0 Posted January 17, 2008 Report Share Posted January 17, 2008 I believe on stock tires, with my 4.10's @ 65 mph I am right at 2000 rpms Quote Link to comment Share on other sites More sharing options...

I believe on stock tires, with my 4.10's @ 65 mph I am right at 2000 rpms On the stock 16" tire combo it will be a little higher. Quote Link to comment Share on other sites More sharing options...

CoolBlueSS Posted January 17, 2008 Report Share Posted January 17, 2008 It should be about what the SS runs. 60 mph I'm at 2K rpm. Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted January 17, 2008 Report Share Posted January 17, 2008 with a 3.73 in mine I run about 70mph at 2000rpms Quote Link to comment Share on other sites More sharing options...
zippy Posted January 17, 2008 Report Share Posted January 17, 2008 i have 275/40/20 In my truck I run 3.73's with a 275/45R20. For a daily driver I wouldn't want more gear than that. If I were doing more city driving than highway I'd go to a 4.10 for the performance gain. For guys running the 275/55R20's like come with SSS's, I would at least a 4.10 gear.
