3.42 gear ratio

New Factory assembled differential.
Comes complete with speed sensor.
Quicker acceleration, will take .5 second off 1/4 mile time.
This is a bolt-on installation with no modifications for 6 speed manual cars.
Lowers quarter mile ET by up to half a second(Depending on modifications, could be more)
Loss of fuel economy is a minimal 1-2 MPG(Depending on driving habits)
Top speed reduced by approx. 10 MPH(Depending on modifications, could be less)
This lower gear ration will greatly improve the performance of your stock or modified 1997-2004 C5 or Z06 Corvette!
The standard automatic trans. gear ratio is 2.73 and the performance option is 3.15. This 3.42 ratio out of the 2001-2004 Z06 Corvette 6-speed, will provide a noticable performance increase in acceleration and with the C5 Corvette overdrive transmission, will only slightly reduce fuel mileage by 1-2 MPG. Not a bad sacrifice for this kind of performance gain!
This is an out-right purchase for a new part, not an exchange program.
NOTE: Custom computer calibration required for Auto trans cars only.
