Mod Mafia Dmax Shift Correction System

Free Shipping!

We are pleased to be the first to develop a complete system to correct the factory shifter setup for use with a Duramax Conversion.  Some of our competitors change the shifter arm, but this is not a complete fix.  By correcting both the shifter and transmission levers, the factory geometry is maintained.  Do not sacrifice by using a "fix" which does not allow use of both Park and 1st Gear.

Includes both Trans and T-case corrections.

*Free shipping on all products in the lower 48 United States.  All others will be billed separately.
