The scatter shield came with grade 8 lock washers, flat washers and bolts to bolt the bellhousing to the block. Should I use the lock washers or just the flat washers? I know the factory only used flat washers. I have read that lock washers could come loose with time. Should I also use lock washers on the transmission or a star washer? Any recommendations.

If the same I would stack then together with the spilt lock washer between the bolt head and the flat washer on the engine bolts and use the washers with the nuts on the other side with the split washers only and use the flat washers under the bolt heads Mr.Cab Racing and winning with Mopars since 1964.

IMO I would use exactly of what the manufacture sent you, they know better than us. Why not? Lock washers work in many applications.

Why because it cost them money! In the event of failure guess where the investigation would begin. One last thing I would call the manufacturer with the question and let us know what they say.

Thanks guys, you have just killed a lifes long belief that lock washers that worked as named since ive never had a nut come off that had a good new lock washer on it. Ive seen lockwashers that have lost there spring (went flat). Now im questing everything in life.
