Worthless
The machining quality was very poor. When installing injectors the "O" ring was getting cut. After several attempts, I measured your product and it was 4 thousandths too small making it impossible for the injector "O" ring to be installed without getting damaged. I did not use this product and recommend that no one else does either.

Didn’t fit my truck
Looks to be a great quality, wonderful price came with O-rings but did not fit my truck I have a 2001 6.6 Duramax They seem to be too short, I don’t know if I just got a bad set or if they are all machined to the wrong size, I compared them to my stock cups and they seemed different so I returned them and got a full refund.
