After the success of our double shear mounted dual kit, we once again listened to our customers requesting even more power with the same durability, rigidity and belt grip. Here it is, the only triple alternator bracket kit for the LS-based engine platform that mounts ALL THREE alternators on the same plane across the top of the engine. Not only is this much more cosmetically appealing, but it also allows all three alternators to be mounted in a standard orientation for incredible eye appeal while also utilizing less heat generated from a typical bottom mount 3rd alternator.  Great for adding external cooling fans at shows and demos!

Not only cosmetically superior to anything on the market, but this bracket also provides hands down the most belt grip and pulley contact of any other bracket on the market. Not just another "alternator holder", this bracket utilizes strategically placed idler pulleys to fully maximize the belt angle and force taking into account a heavily loaded down alternator.  No slip, all grip, all power!

Enjoy an easy ONE TOOL idler adjuster. With our "square-lock" adjuster slot you can simply loosen one bolt with a socket/ratchet to make any adjustments needed for proper belt tension no matter what pulley sizes you might want on your custom setup. No more reaching behind the bracket and holding a wrench on the nut and loosening.  Turn, slide and lock it down!

After months of real-world R&D with daily 400-500-600+ amp draws while also driving, there has been zero "belt walk", zero belt dust and no bracket to belt contact.  All major belt slip/chirp on vehicle wide open throttle shift has been minimized as much as possible with most vehicles only experiencing a slight chirp at WOT when accelerating from a dead stop and shifting into 2nd gear. We have tried to torture test this setup just like anyone could...but SHOULDN"T!
