These converters are great for most diesel owners that want an upgrade from stock at a moderate price level. The triple disc will greatly improve lockup and holding capability. However, this converters cast stator limits its ability to accept big power and handle heat.
These are the go to converter for all diesel owners that want to the best. Youll find these converters in tow rigs, dyno queens, drag racers and sled pullers where boosted launches and extreme power are prevalent. These converters billet stators can handle double the power and heat of a cast stator.
