just put my gears in over the weekend, everthing went fine. Was wonder about breakin. What do you guys recommend.

Thanks,

 

Most manufactors will have a suggestion on how to break them in, but if oyu are like me they probably ended up in the grease rag pile and are in the trash by now. For the most part I have noticed that manufactors suggest a driving (warming up of the gears) and a cooling down period, anywhere from 3 -5 cycles. Should set your gears fine.

 

I have the instructions, but they have no breakin procedure.

 

1,00 miles is what i did. Basically don't romp on it. Take it easy.

 

I hope that you know not to tach it when heading down the road. I would just take it out for 15- 20 mile drives, let the truck cool and do that for the next four or five trips. It gives the gears a chance to expand and contract and settle in

 

^Do this about 4 or 5 times first thing.Then take it easy on the gears for at least the first 1000 miles. Just ease into the throttle, keep the rpm's as low as possible.

Thats what my installer said when i got mine. I've had them for about 5k miles now and no problems.

 

Follow the directions of the last two posters......and...varied speeds with no loads in the truck the first 1000 miles to be safe, especially don't tow until breakin is achieved.

 

Randy's Ring & Pinion has always had a great FAQ regarding gear break-in...

The object is to get as many HEAT/COOLING cycles as possible in the shortest period of time. About fifteen 10-15 mile "Short trips" with COMPLETE cool downs in between. After that Just easy driving Never exceeding 60MPH for the first 500 miles. This helps harden the contact surface of the gears which is their lease on extended life.

After the first 500 miles, change the fluid and drive it like you stole it.

Your going to love your 4.56's! Hands down one of the "SINGLE" mods I have done to date.
