I am (or possibly was) hoping to get my 3.54 ring and pinion gear swapped OUT and a new Dana/Spicer 4.10 installed in time for my car club's annual track day November 19th. My amazing Passon a855 5 speed has paved the way for me to have the benefits of the 4.10 yet I will still be turning 700-800 less RPMs in 5th than I used to turn in 4th with the 3.54. This is my parts list:
OEM Spicer 4.10 ring and pinion $285
Master bearing install kit Timken USA $150
OEM Spicer Power-lock clutch pack $79
Timken USA Set 7 wheel bearing kit includes inner steel gasket, outer foam gasket and inner and outer seals $95
The concern is that my mechanic is concerned about the break in time/mileage.
I'm thinking dedicated track cars change ring and pinion gears, and what kind of break in process can they possibly have that I can't do better than, even in a short period of time, since I drive my car on the street and highway.
Advise please? Thanks.
