Gears...

[95StangMan]

OK i had my gears installed on Thursday of last week (3.73's). The guy who did it told me that i probably should not drive hard on them (burnouts racing etc.) for the first 500 miles to break them in. the first 200 being essential. I have put about 190 miles on them now. I am hoping to get that to about 250-275 miles by wed so i can race that night. Should i wait to get to the 500 mark or is it ok to race with about 250 miles on them.

Thanks

You could have beat the balls off your car pulling out of the parking lot right after the gear swap. NO need to wait 500 miles. Go race and enjoy

When I had mine installed a few years ago, I was told the same thing... wait 500 miles. I waited, just to be on the safe side. But I have heard both sides and have not heard anything that completely convinced me oneway or the other...

I left the shop and went 15 miles to the drag strip it was fantastic. That was 2 years ago and no problems yet.

Now thats how you do it

i put mine though about 4 good heat cycles, which took about 100 miles. but i dont think it matters either. i should have just pulled out and hammered it.

I've always put a few heat cycles in em before beating on em.

That way has served me well for over 20 yrs of time.

As for the amount of miles I drive during the break in period......I'd say no more than 25 to 50 miles at the most. IMHO, I think the heat cycles are more important than the amount of miles.

Follow your installers advice...it will eliminate one variable (proper break-in) if something comes up later on. You won't be "stuck" wondering...

Breaking them in is always a good idea...just like after installing a clutch.

It is potentially damaging to the owner's wallet to just tell them to go "beat on it"...

I think after a couple hundred miles (as in your case) and you notice any problems...your good to go...

what exactly is a heat cycle.

 

[AUcobra94]

Heating up then cooling down.

 

[DFG 5OH]

but how...i knew that

 

[AUcobra94]

When you drive the rearend heats up(friction). Drive about 10 miles and then touch the rearend, its hot.

 

[DFG 5OH]

omg, i cant get a straight answer.

Lemme get this straight, a heat cycle is drive the car for 10 min. then burn my hands when touching the rearend?

 

[AUcobra94]

omg! lol

 

[clang5oh]

well the ones i got are used but not by much. i am going to put them in at the track after my last run with the 2.73's

 

[DFG 5OH]

how much you want for them?

 

[davins130]

heat cycle them twice, then your good to go, the guy who did mine heat cycled them for me so on the 2 hour drive home i drove the **** out of it

 

[bad98sst]

well since im so cautious i drove the first 150 miles not going more than half throttle
