Where can I buy 4.10 gears for a good price?

[K1500 gramnolds]

I`m looking into getting new gears for my 89 K1500 ECSB. I have already gone up from stock to 285 75 tires and it caused a little bit of "lag" on acceleration. Currently running 3.73s and using the speed calculators I found online, the difference at 2200 rpms in OD on a 700R4 is about 7 MPH. It says that RPM should be 75mph for 4.10 and 82mph for 3.73. I`m not terribly concerned with gas mileage as this truck rarely goes on long trips. I do use it for working and hauling a lot of stuff and don`t want to cause un-needed stress on the axles under load with the higher gears. I don`t have gobs of money to throw at "racing gears" either so I need some good value new ones or used in good condition if I can get them.

If that is all your going to do, 4.10s should be fine. Lower gears will add stress to the axle but unless your pulling max loads everyday, i dont think you will have a problem. Some others may have some better input than i do though.
