Got my 4.10s in yesterday. Gears + labor was 475 out the door. A little high...but hey, I really trust that shop and the quality of their work. I happened to have a day off yesterday and called them around 2pm. They did my gears and chip/tune in about 3 hours. They didnt have to squeeze me in but they did anyway.

^ what did you use to recal your speedo?

tough decision........im thinking of going with the fr500's and holding off with the 4.10s untill winter what do you guys think?......oh and i realize some of you guys are going to think gears are only like 200 right lol.....but with installation and all that stuff will bump it up to around 8

800? You can get FRPP gears for 140. My install took 1.5 hours and was 200. I bought my own fluid and friction modifier.

i guess shops around me are real exspensive.....keep getting quoted at 400........and as far as correcting the speed what should i use? if i go to a tuner could he just fix it ?
thanks

If you already have a handheld programmer, some can change the speedo. If not, you need to get a Speedo Recalibrator. I think they are still around 80-90 dollars, and can be purchased from Dallas Mustang, Brothers Performance..... etc.
