40...
Shipping was fast, but I installed and the driver locked up within 2 min. Currently waiting on call back after sending picks in to person named Scott. When I called in he was very friendly and informative so hoping I here something today as to what can be done

40 series aftermarket Torque...
Pros:
It arrived on time as stated,
It was easy and fast to install. about 20min
Cons:
Box was damaged and ripped pretty badly,
Packaging was cheap bubble wrap on steel components,
All mounting hardware is cheap grade 5 crap,
The link for the 420 chain hits the driven pulley.
Overall thoughts.
I used this on a Predator 420cc Hemi engine with a header pipe, I do wish for the price you pay for this kit it would come with grade 8 hardware and they would use a foam filled packaging instead of bubble wrap. I wish I could move the 10T gear over just a smidge it would work great, I also wish the driver would come with a higher engagement level instead of the 1600 RPM set up. I do believe it's made so you have to buy new parts to upgrade it. At least install the green driver spring to help hold it open a bit longer and that would make it a little more worth the prise you pay. -

Bent jack...
When I received my 40 series torque converter kit, the jackshaft was bent. After contacting customer service, two days later I received a new jackshaft and bearings. No questions or cost. Absolutely fantastic customer service. Customer for life .
