Running dual alternators leaves the factory charging system intact doing what it was intended to do, while the secondary alternator carries the additional accessory load. By effectively doubling the available amperage you can run more accessories with less worry and for about the same cost as a good High Output Alternators. Our Heavy Duty Alternators perform under adverse conditionsand are made from quality "original equipment quality or better" components unlike many of our competitorsalternators that are made from imported "cheap" parts. We guarantee our product! Beware of imitation kits with cheap high amp alternators!


This kit utilizes either a secondary factory dual-spool mount alternator, or if needed a highly dependable, high output model. This allows the end user the ability to use two separate alternators and two separate batteries without the need to use a battery isolator for the ultimate in safety and dependability. By
running an auxiliary alternator you can dedicate all of the accessory loads to the auxiliary charging system and never have to worry about overworking the factory alternator. In the unlikely event of the auxiliary charging system having a malfunction, the vehicles factory charging system remains functional
thereby enabling the operator to still operate the vehicle normally and get it back to the facility for repairs.

Our Dual Alternator Kits come complete with the mounting plate, support bracket, idler pulley, Premium Quality Belt, and all grade 12.9 mounting hardware. We also supply our the necessary wiring to make it true plug and play install (Pre 05'). We manufacture the kits here in the USA. Unlike some "erector set" multiple alternator kits on the market, our kits are made from solid 3/8" STEEL, and the alternators mount securely to the mounting plate and the engine which makes installation very simple and secure.

*Also fits Express Vans with different Alternator, Make sure we know if you have an Express Van.
