Welcome to the future of Street/Strip converters with a 12″ lockup. Yes, you read it right. Hughes now builds a 4000-4500 stall converter while retaining a 12″ lockup cover.

This is made possible by using a 12″ cover with a 10″ top. Not only is a 12″ cover used but the piston is modified to incorporate 80% more friction surface! This solves the dilemma of higher torque producing motors exceeding the ability for a 10″ converter to retain lock up. The custom built units incorporate a ll the same features as our Performance 3500 Series.
