Break-in / Rem Info

As with ALL differentials ours needs a proper break in period. This allows the gears to work harden and smooth themselves before prolonged hard use for cooler operation. If this isn't done you are risking expensive damage to the gear set that can only be fixed by replacing the gear set.


There is no hard and fast rule to cover all situations as to the proper way to break them in. The key is to get some miles/time on them in short increments while not allowing them to overheat and break down the fluid.


Recommended Gear Lube

 

  • Best choice (non-racing): https://www.currieenterprises.com/why-run-conventional-gear-oil OR Torco A248514CE - Torco RGO Racing Gear Oil GL-6 
  • Alternate option: GL-5 rated 85w-140 standard (non-synthetic) gear lube.
  • For rear applications in desert racing use 2 ½ to 3 gallons of Swepco 203 moly- 250 weight available from SWEPCOUSA.com.
  •  Proper gear lube AND break-in is much more critical on a high pinion differential because the gears are NOT submerged in oil like a low pinion would be. 


In certain situations, especially racing, there is very little time if any to properly break in the gears.


We are now offering a REM finishing process to the gears to help with this problem. Most every NASCAR team REMs their gears to help avoid the heat buildup associated with racing. This is NOT a guarantee that you will not wear out your gears from improper break in but it will dramatically increase your odds and for sure they will run cooler.


The cost of this is $300.00, we are sending them to a company that does NASCAR gears for this service. The cost comes from the cost of shipping them there, the process, and shipping them back to us.


Please allow an extra 14 business days to your order if you want this done.
