The Ultimate Bolt On Torque Converter Kit for 8-18 HP engines. This TAV Kit is specifically for big block engines (Predator 301/420, GX270/390, etc) with 1" Crankshafts. If used on engines larger than 18 HP, you will burn up belts.
We recommend you use an impact when installing these parts. Failure to do so may result in the torque converter coming apart and possible injury.

Engagement it got stuck after a while and I almost drove into on coming traffic I had to shut the engine off and slam on the brakes it gets stuck and does not want to go back
Clutch stuck after only 2 hrs of light use. I have put in to return the item but it still says pending
Excellent quality and easy to install. Smooth take off and smooth power. I would highly recommend.
40 Series Torque Converter Kit - Bolt On, 8HP - 18HP
So far so good haven't had time to put it on my cart yet but I will do another review when I do.the plate it mounts on the engine with is nice and thick and plenty of mounting holes.
High quality part. Looks great, can’t wait to install it!
I went around the block 3 times felt a pop and lost torque/power the back spring/pulley does spin but that’s it looked at it and saw pieces hanging looks like weld or something busted not too sure
Good quality but my drive clutch likes to stay engaged when i stop.
Very nice quality and works great. The 4 5/16-24 x 1.25 mounting bolts are .250"
too long and had to replace them with 1" bolts.
