Input to output shaft bearing/seal support kit

Product Description

Ever noticed theres nothing supporting the input shaft to output shaft on your 4l60 series transmission ? Theres literally nothing keeping the centerline running true. Take a moment to stack the whole geartrain up piece by piece starting at the back of the input drum- youll notice it gets better with every part you stack on. Youll also notice when its all said and done its still sloppy.

With this center support bearing and seal kit, the centerline of both shafts is maintained and runs true. In back to back vehicle testing weve noticed less vibrations and smoother operation with it than without.

Output shaft requires slight machining. We can provide if billet output shaft is purchased.
