4.10/4.11 Gears

I'd like to get 4.10/4.11 gears for my 2000 C5 Z51.

Dynotech sells completed diffs for $1.3k
http://www.dynotech-eng.com/dte_c5_diff.htm

The ring and pinion gears are $320 from Rons-Machining-Service but I've heard it's very difficult to install them yourself and special tools are required.

The labor cost from Dynotech is about $900 assuming $80 for misc materials. At $50 and hour, that would be 18 hours. There is no way this is an 18 hour job, is there?

Has anybody tried having the ring and pinion gears installed at your local Chevy Service Center? If so, how much did they charge you and did you have good results?

Maybe somebody on this forum (not me) should learn how to do the swap and only charge $400 plus materials.

post up your location...maybe there is a shop in your area that has the correct tools to do the job....

you can also save some $$$ by doing the diff R&R yourself....

I got a quote from the dealer in Fargo, ND of $1000 labor for 11.5 hours of work. That's even worse.

The dealer in Jamestown, ND said $869 labor and 11 hours of work. If you add in $320 for ring and pinion and $80 for misc materials, total is $1269.

my 4.10 diff was taken out of the car, cleaned and rebuilt with stage 4 internals, and put back in the car in about 5 hours at RPM. just buy one from there and send a core.
