BD Power Allison Valve Body 2004.5 to 2005 6.6L LLY Duramax

Shop with Blessed Performance for the BD Power Allison Valve Body for your 2004.5-2005 GM 6.6L LLY Duramax diesel. The Allison exchange valve body saves installation time over installing a shift kit.  In less then 2 hours you can be back on the road with confidence your transmission is holding up to the loads you are pulling or the increases in power produced by installed performance boxes and tuners.

The Allison valve body is a must for trucks towing moderate loads or racers who have increases of 90rwhp to 120rwhp.  For heavy haulers or extreme power, we suggest further transmission modifications or exchange out with one of our heavy duty transmissions and convertors.
