i am looking at 4:10's on Ls1speed.com
http://www.ls1speed.com/catagory.cfm?catagory=rearend

just wondering what the differecne is between the two. I know the GENUINE GM gears are boxed by motive...but what is the difference?just for the ring and pinion and install kit the GM gears are 20$ more.

But i am thinking about buying the 530$package which includes gears w/ install kit,ta girdle,and a speedo calibrator. Does anyone kno what speedo calibrator they use?

Think that package is worth it.

hey i bought my gears there.... motive.. with the install kit, and they are awesome!!! not a problem at all!! no whine... and they are pretty much the same gear... i think the spedo calibrator is just a hypertech programmer. i had mine adjusted Via a mail tune..
