Venom Automotive 2JZ Alternator Support Bracket to reinforce the lower alternator tab on the 2JZ-GE & GTE blocks. Commonly these tabs are breaking off from fatigue or over tightening during installation of the alternator.

This bracket will reinforce unbroken tabs as a precaution to failure or assist in supporting the alternator where the original mounting point has broken off (as pictured). Please note we recommend that the block tab is tacked in place to evenly support the alternator mounting face.


Compatible with Mid & Rear Sump Arrangements. Not Compatible with Front Sump Engines.
