Adding a second or third alternator is a direct way to raise charging current for a large system, and Mechman dual and triple alternator bracket kits make it practical on GM trucks. Kits cover 1999 to 2013 GM trucks with 4.8L, 5.3L, 6.0L and 6.2L engines, in bracket-only and complete versions with alternators in black, red or blue.
Mechman alternators are often built to order, so check each listing and contact us to confirm fitment.
A bracket kit adds mounting points for one or two additional alternators on the engine, driven by the accessory drive with revised belt routing. Each alternator adds charging current, which helps a large amplifier setup hold voltage during long listening sessions or competition runs. Mechman alternator bracket kits are engineered around specific engines, so the year range, engine and pulley arrangement on each listing matter more than anything else.
The dual kits in this collection cover 1999 to 2013 and 2005 to 2013 GM trucks with the 4.8L, 5.3L and 6.0L, plus the 6.2L on some kits. A triple bracket for late 1999 to 2013 GM trucks supports three alternators for very high-current builds, and a laser cut adapter bracket serves select 2.2L SOHC GM engines. Confirm your exact year, engine and accessory layout before ordering; we are glad to help verify it.
Bracket-only kits include the bracket and kit components, so you supply the alternators. Complete kits pair the bracket with Mechman alternators, such as the B8302370 and B8206400 models, in red, black or blue finishes for a matched look under the hood.
Each alternator needs its own output cable, sized for its rated current and the run length, and a fuse or circuit breaker near the battery end. Upgrade the main charging paths with a Big 3 using 1/0 AWG power wire or heavier, and make sure the battery bank can absorb the added current; browse batteries for AGM and lithium options. Keep the alternator output voltage suited to your battery chemistry and voltage. Return to the main alternators collection for single high-output units, harnesses and regulators.
