EXGM Posted March 21, 2015 Report Share Posted March 21, 2015 Just found out truck has 4.56's on the hwy it cruises at around 2500rpms at 70/75. I'm about to move to Texas. Do yall think it'd be ok to drive or should i tow it? I'm curious why you think you have 4.56's? They don't stamp gear ratio on housing... I could be wrong but I am 99% sure. On a 2006 SSS they only came with 3:73's.... Quote Link to comment Share on other sites More sharing options...
8hnpSS Posted March 21, 2015 Report Share Posted March 21, 2015 SS trucks never came factory with anything other than 4.10s for AWD and 3.73 for RWD. my awd SS runs around 2500 at 75 Quote Link to comment Share on other sites More sharing options...
desrtrat Posted March 21, 2015 Report Share Posted March 21, 2015 with stock size tires, you will be at 2300 rpm at 70 mph.. Quote Link to comment Share on other sites More sharing options...
Hotrdchvy350 Posted March 22, 2015 Author Report Share Posted March 22, 2015 It wasn't stamped on the housing it was stamped on the ring gear that's what the picture is of It really doesn't do to bad by the mpg computer on the dash it did 16-17 to okc and back SS trucks never came factory with anything other than 4.10s for AWD and 3.73 for RWD. my awd SS runs around 2500 at 75 Never said it came with it, when I pulled the cover I was pretty sure it had been into before. I just knew when I got on the highway the rpms were a lot higher then the other 99-06 trucks Id had previously so I just pulled the cover and changed the oil figured it couldn't hurt. And counted the gears and checked the stamping on the ring gear Quote Link to comment Share on other sites More sharing options...
JC03SS Posted March 22, 2015 Report Share Posted March 22, 2015 I'd think with 456's it would turn more rpms. Mine is Awd and its 2500 at 80mph. Quote Link to comment Share on other sites More sharing options...
Hotrdchvy350 Posted March 23, 2015 Author Report Share Posted March 23, 2015 Idk man all I can go off is what was stamped on the gears and counting the gears 41/9=4.55 Quote Link to comment Share on other sites More sharing options...
