Going to a 410 rear end
I'm in the process of deciding on a change to a 410 rear end in my C5 vert (14,000 miles on the odometer).
Can the diff just be pulled and new 410 gears added as opposed to a core change swap with all new parts, I assume.
also on the diff swap, I was told that you have to break in the new rear end slowly, keeping it under say 50 miles per hour (or slower) for the first 200 miles. Would this be true if you were just swapping gears?
Why would this be; a new car doesn't have to be broken in as far as THE REAR END IS CONCERNED.
Please advise why and the best route to go.
Thank you.

I would break the new gears in for 500 miles. Might as well be safe about it. I also break in my new vehicles as well because although they may already have done a engine break in, all the other parts of the car need to be broken in. Varying speeds and gears and stay away from highways where you maintain the same speed for longer than a few miles.

To get the best advise in answers to your questions... it would be best to fill out your profile to include year of car, mods, manual/automatic,
present rear gear ratio, state you live in etc, etc.
Good luck.

GM tests the differentials for noise before installation into vehicles but they still need to be broken in. If you get new 4.10 gears, you MUST break them in properly (varying speeds for 500 miles) or they will whine. If you decide on 4.10's, the car will be much more lively!!!
