I put this on a aftermarket 40 series Torque Converter, I had to lubricate the clutch and driven with Teflon spray, because the parts that were inside the unit had no lubrication. Once this was done the stall kit worked perfectly. Great product and I would definitely recommend this for a go kart or mini bike with a 40 series torque converter.
Great quality and easy to install, can’t wait to try it out
Excellent addition to my 40 Series. Made a world of difference in the off-the-line performance of my build. The staff at GoPowersports answered my questions quickly and made sure I got the right parts. Super easy install. Couldn't be happier!
