Review on Helicoil 5546 8 Metric Coarse Thread by Travis Caminiti

The helicoil kit is what it is and does a great job if you take care to install the coil correctly. I bought my first helicoil kit in 1969 to repair threads in an aluminum cast on my Harley Davidson XLCH Sportster. The new Helicoil kit is designed to repair the cam bearing cap threads (metric) on the aluminum head of my Toyota V-6 engine pickup truck (1994). I stripped a thread on my Harley but a previous mechanic stripped a thread on a Toyota.
