question on new gears ( break in )

[96 myst]

I am gonna be picking up my cobra tomorrow from the mechanics, they installed new frpp 4.10's along with all new bearing etc. What is the proper way to break the new gears in?

Thanks in advance

never broke in the 3 sets of gears i had and never had an issue. Well actually i break then in with a nice launch on slicks. My last rear i finished the night before a track rental then made 10 passes launching from 6,300+ rpms. That was with 4.30 gears

no break in, just drive it

DTS recommended using 85-140 non synthetic gear oil for break in.
Drive the car 30 miles and then let the rear completely cool down. Do this cycle 3 times. Then after 500 miles change the break in oil to lube of your desire. They recommend Amsoil 75-90 full synthetic.

This is the procedure for a car that will see some street duty.

This comes from company that has built thousands of custom rear ends.

Last time I had the 4.10's swapped in I left straight from PSR to Speedworld for some nice redline launches on slicks and the bottle.

nobody actually follows that there is no reason to. My car was street driven even with 4.30s had no issues. 4.30s were in my daily driver for over 2 years now, before that had 4.10s for 2 years with no issues either on my old gt. Mustang magic who did my car did at least 2 or 3 gear swaps a day at least and they said no break in required. 45 minutes in and and on a gear swap. 4.30 gear swap i did with a friend that took about 2 and a half hours hardest point was setting the backlash
