JUNK JUNK JUNK JUNK. PRO-TEK Must have bought these off of EBAY from China!!! If you run MOD, you will destroy these!!!! The reviews on here with 5 stars must be for guys running 17.5 and 13.5 or loose diffs. You can watch every YOUTUBE video for building and breaking in diffs, and it wont help these balls. Like the saying goes, "You get what you pay for." and.."If it sounds to good to be true......" I run a B44.2 with 8.5 SONIC. Decided to try these after getting a year out of the stock carbide balls. These felt really smooth after break-in and final setting. After 2 days of practice they started to feel like worn carbides. Disassembled diffs, cleaned, flipped rings and polished, re-assembled and broke-in again. Worked great for a couple weekends, decided to run them out. Made it a total of 12 practice days, and when they were done they felt like gravel. Another experienced racer i know, tried these in his B4.2, and had the same results. I have had Team Associated ceramic balls out last my outdrives. Save time and frustration, for a budget purchase get the MIP balls for $3
