My analysis of this kit showed that it was not up to par with other thread repair kits on the market .The pieces seemed flimsy and not durable. The one positive was that it did come with a few extra inserts. However, the cons outweighed this small benefit and I would not recommend this kit..
Pros
Improved engine performance and power
Cons
Potential compatibility issues with non-Triton engine models
I am no longer impressed with these inserts. You are definitely on the right track. I installed it with an ATD 5400 (although the CalVan is exactly the same).
