1995-1997 GM Truck-SUV Big 3 Upgrade Kit, Gas Engines

Price range: $264.95 through $314.95

This Big 3 Upgrade Kit has been designed specifically to accompany our 1995-1997 GM Truck-SUV Battery Cable Kit, Gas Engines.  The cables included in this kit are intended to complement the installation of a high output alternator and are in addition to the ones included in the Battery Cable Kits.

Our 1/0 AWG kit is perfect when adding our Mechman 250A Alternator for your truck. Our 2/0 AWG kit is perfect for our Mechman 320 and 400A Alternators.  All available below!

We recommend choosing the fuse as close to the output rating of your alternator as possible. For example, choose the 250A fuse for a 250A alternator.

See Description below for specifications, performance, and fitment specifics.  Additional parts required if you are using the stock battery cables – outlined below.

Product Development

We developed this kit fully in-house to fit perfectly and offer exceptional performance when upgrading the alternator!  We built, installed, and tested our 1/0 AWG Big 3 Upgrade Kit along with one of our Mechman 250 Amp Alternators for the same truck (offered below) in a 1997 Chevrolet Silverado 1500!  The Next Chapter – Complete In-House Product Development tells you all about the process.

As you can see, our kit fits beautifully and man does it deliver the goods when paired up with a Mechman high output alternator!
