I was looking into getting some 4.083 gears from everythingg35.com and then i wanted to do some research on the install price so i went to a race shop, Extreme Motorsports, and they were trying to charge me 365$ just for the install. Anyone else have a price on some just so i can compare, i really have no clue for the cost and i will not attempt it myself

Is that Sean Glazer's Extreme Motorsports? If so his shop has always been on the higher side of prices. His shop is geared toward DSM's. Why don't you try this one yourself?

Is there a DIY on this floating around somewhere? I am somewhat interested in this myself

thats not a bad price to get it done correctly and shimmed

That actually doesn't sound too bad. You DON'T want to mess with gears yourself.

id gladly pay that for someone to set the rear end up properly. if you dont shim it right, you will ruin the ring and pinion.

That sounds like a good price.

i was thining about taking it to a nissan dealer.

thats not bad especially if they are going to shim it properlly...

Does the shop stock every shim size for the pinion gear and differential side bearings?

Usually when I would send a gear set out to be built, I would send one of every shim size that could be needed so there is no down time.

That is unless the shop will make their own.

If not, you will end up with a noisy rear end and some damaged gear sets...

Believe it or not, most NISSAN dealers do not have the tools to properly measure for tolerances in the rear end. They don't do enough of it to justify the tools... They will sublet the work to a local gear shop most likely.

This is not a good DIY. If there is anything on the car you should to leave to the pros, this is it. It has to be absolutely perfect if you don't want excessive noise and vibration. A multitude of shims are required on hand to ensure you have exactly the right ones for the install. $365 sounds just fine for a professional shop to do it right.
