Put an end to loosening turbo bolts. These little washers are magical. If the nut or bolt starts to back out, the ramps on the washers will cause everything to tighten up further. Because these ramps are steeper than the thread pitch the nut/bolt will find it easier to simply stay in place. Vibration testing shows they are far more effective than mechanical locking nuts. Unaffected by lubrication. They're not cheap but they're worth it. Stainless steel for high heat applications. Included in all FM turbo kits. Price is for one two-piece washer. Five required for the turbo-to-outlet joint, and four at the outlet-to-downpipe. Or, get yourself the complete hardware kit below. We used to use these at the turbo-to-manifold joint, but have since upgraded to Stage 8 nuts (with our proprietary Inconel studs) - pick up that kit above if you'd like.
