RECOMMENDED FLUID: When ordering your MFactory Helical LSD, we highly recommend that you order our Torco Manual Transmission Fluid (MTF) at the same time. For your convenience, we offer Half Cases (6 x 1ltr Bottles) which is sufficient for the initial break-in period of your new transmission component(s) (approx. 1 tank of gas) and the subsequent fluid flush. DO NOT use Gear Oil in your Honda Transmission. Doing so will cause more damage than good, especially the expensive Synthetic/Performance Gear Oils. Please click here for further information.

RECOMMENDED BEARINGS: When ordering your MFactory Helical LSD, we highly recommend that you order new Diff Bearings at the same time. All of the bearings that we supply are high quality OEM replacement Japanese Bearings. Prices are Per Pair.
