stroked out Posted May 11, 2008 Report Share Posted May 11, 2008 Well as some know I have the 4l80e in my ss. I was reading some post on the long first gear of the 4l80e so i want to gear down a bit to make up for that first gear. My question is what gear would be good for a good launch but still be streetable (meaing no reving to the moon at frewat speeds) With my 4:10s and the 4l80e OD Im reving about 2300 at 60mph Thanks Quote Link to comment Share on other sites More sharing options...
04CHASE Posted May 11, 2008 Report Share Posted May 11, 2008 id stick with the 4.10's man i know some have put the 4.56 in but they will be getting high rpms and crap mileage. shoot at 70 i think im around 2300 rpms and thats a bit high imo. in my maro with 4.10's im @ almost 80 @ 2000 rpms.(t56 are nice) but i thought you were going with a radix lq9? that should have enough low end grunt to work you through that 1st gear good.

03AWDST Posted May 19, 2008 Report Share Posted May 19, 2008 Hello Guys, I want to go the other way. My SS has the 4L65E Transmission. What I want to do is down grade my Gears. With the cost of Gas these days, I would like to change to 3.73 or 3.43 gears. I know that his is a very heavy truck. Do any one have a ideal how the truck we run at speed limit with both of those gears? 562 H.P. 03AWDST Quote Link to comment Share on other sites More sharing options...
