question on new gears ( break in )

[Ruckus46gt]

Read above. Drag car does not require the break in. This is for a street car.
There comes a time when one should stick his foot in his mouth. You have reached it.

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

Well, seems both ways have worked for many people. I have decided that taking a few extra minutes is not gonna hurt me any and will heat them up and let them cool a few times. Better safe than sorry.

Thanks guys

Make sure you use the right oil. Some will make grinding sounds.

Good decision.

Nope just trying to provide information from pro rear builders and gear manufacturers.

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

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.
