Crank polishing: Extends bearing life, reduces oil temp, frees up a slight amount of average horsepower. This is a very low cost upgrade, and in the world of mass production, most cranks do not come with a true polished finish. This is why most machine shops have a machine to do this. The difference is dramatic between a crank right out of the box and one that we have polished. Bearing companies claim that cranks that have better finishes on the journals will survive the break-in better, and have much longer bearing life. We do a three step process and bring the RA numbers down in the single digit range. We have the most advanced crank polishing machine on the market. We find this to be an excellent upgrade for your engine build, considering the low cost. We polish the crank for every engine we build. Cost for this crank polishing upgrade is $38.50 We have this upgrade featured in our other listings. You can see this and other upgrade options in our ebay store under the "UPGRADES" category, or simply do a search with the key word, "Upgrade" in the search bar when shopping in our ebay store.

The appearance of the journals show a dramatic difference once polished. |
