I was quoted at $150 to get a set of 4.10s installed by a very reputable local shop. This does not include the gears obviously, I'll end up buying them from LMR for 150 if I decide to do this. Is this a good price?
I was originally saving up for a set of track rims (big and littles) and a suspension set up but I could put a hold on that...

 

I paid $250 for my gear install, so $150 seems pretty good! Do you have a tuner to recalibrate your speedo?

 

+1 I paid about $300 for my install.

 

I don't have a tuner. Will the shop do that for me or do I need to buy one?

 

You will need to buy one, or you can get a speed cal for 100 bucks and install it yourself. It was easier to install than what I thought it would be. Otherwise your speedo will read way off.
