question on new gears ( break in )

[BurnTire]

yea they "do not require a break in", but will see the same rear end temps as a street driven car but will put more of a beating on the rear. So both rears will see the same temps, one will put way more of a beating on the ring but yet that one doesnt require a break in. Makes a lot of sense. Rear doesnt need a break in drive it normal go to the track you wont have any issues with it

A dedicated drag car is not worried about putting 50,000 miles on the ring and pinion. Second a trailer queen is not going to see the same rear temps as a street car. Drag cars need only an initial run-in since they are driven short distances and heat is not normally a problem with proper lube and backlash allowance.

Driving the car normally to the track is a break in cycle. I am glad to see you see the light.

You do not use synthetics on a new ring and pinion because of the break in requirments.

if you cant use a synthetic on break in what does ford do in the 05 and newer mustangs that say synthetic only dirrectly on the rear end housing

i break in gears the same way i break in clutches, at the track, and then i just wait 300 miles for 2nd2nunn to break the clutch, but seriously i break them in at the track

wow someone can read a books. Hate to tell you the rear end temp of a pass will be much higher then a car driving 10 miles which according to you would be harmfull. Tall gears and high mph is a lot of friction. Aftermarket gears come coated with 'Phosphate', 'Cosmolene' (sp?) or other coating to prevent rusting/pitting during transit or storage. The reason you shouldnt use Synthetic oil is that it clings to the gearteeth and doesn't shear like conventional oil thus taking much longer to create the pattern. also if i live in az or north dakota my 10 miles with an hour cool down wouldnt there be a difference in rear temps? So the info you are posting is vague in general. What they are telling you is a cover my ass response, but its not necessary. I will put money you will not have any issues getting on it as you leave the shop, besides maybe an unsafe start ticket if a cop is nearby. Remember if you live 30 miles away from the shop its going to take you about 3 and a half hours to get home lol
i'm done you've read it all

Go out and work on your 13 second car. You made of fool of yourself on the wheel backspacing and your doing it again.

Yes create a pattern that is a break in Mr. 13 Second.

The entire purpose of the break is to ensure longevity of the ring and pinion.

I have never seen anyone make such an issue over something that only takes a few drives to accomplish.

You act like it costs the owner a $1,000 to accomplish a break in.

Nope. Just having fun on the internet

I have known guys to not break-in things properly from gears to clutches etc..

I always went by manufactuer specs on all my stuff...especially on gears and clutches.

There is a right way and a wrong way to do things....not saying the "wrong way" means the rear will explode, heck it may last (I wouldnt know) but I do know these companies recc break-in's for the reasons Jeff has already pointed out.

Some of us don't want the hassle of short-cuts because people with my luck should understand why i try and take every precaution to ensure my car is done right. LOL

wow we are mr tuff guy. Yea i own a 12 sec car and only had a 12 sec 2v. Sorry never felt the need to become a cobra owner. Did i think about it yea but people like you are the reason i havent. All cobra owners think there shit doesnt stink.
Hey torch did you swap out rear ends when you put those 28's on? I proved 28's would fit on a 99 up rear know many cars doing it. You just need to stop being a nut hugger. So while you are at it can you read a book and let me know how the cooling down process gives a different wear pattern then if you were to drive the car straight through
