SVE 130 Amp Alternator 1G to 3G Upgrade Kit

This SVE 130 amp alternator upgrade kit gives your 1982-1985 Foxbody Mustang more charging power for your accessories! 1982-1985 Mustang stock alternators suffer from small wiring and low output. Add underdrive pulleys and running your accessories such as headlights, A/C or the heat and you'll likely see the lights dim and the battery gauge drop. Throw an electric cooling fan into the mix and the stock alternator simply can't keep up. This kit gives your Fox Body Mustang the extra charging power it needs to keep your electronics running smoothly!

Increased Amperage

Our 130 amp SVE alternator is 100% brand new, no core charge, and carries a Limited Lifetime Warranty. This alternator is from the internally regulated 3G series, includes the correct pulley (installed), and produces 75-100 amps at idle when used with the stock crank pulley and the included alternator pulley. The idle output of the SVE alternator meets or exceeds the peak output of the stock alternator! SVE's alternator is rated at 130 amps continuous output but is capable of producing 160+ amps at peak. A dyno sheet, specific to every alternator, is included with every alternator to verify these stats.

4 Gauge 3G Power Wire Kit

This kit includes a complete upgrade to the main power feed wire from the alternator to the vehicle. The OEM wire from the alternator to the vehicle was not designed to carry the added load of higher amperage alternators. Using this large (#4 Gauge) wire kit will add the safe carrying capacity needed for lengths up to 10 feet. When using our high output alternators you must upgrade this cable to retain warranty coverage. It also includes noise suppression for aftermarket radios.

1G to 3G Upgrade Kit

This kit includes a 1G to 3G upgrade for the installation of a Ford 3G alternator on any vehicle where the stock alternator was EXTERNALLY regulated. We incorporate a new replacement external regulator box (as shown) to capture the proper circuit and retain the stock wiring harness along with our own 3-wire (3G Series) regulator plug. This kit allows the customer to retain the OEM warning lights and shunt-type ammeter. Installation requires replacing the stock external regulator with the one provided, installing the alternator and our 3-wire plug, then make one crimp connection from the original wires at the alternator.

Alternator Bracket

If you are looking for a replacement 1982-1993 Mustang alternator bracket for your 5.0 motor, 5.0 Resto has you covered! This direct replacement aluminum bracket bolts directly in place of your factory bracket and are manufactured for extra clearance to allow mounting of larger alternators such as the popular SVE 130 amp alternator. This bracket is a 5.0 Resto exclusive, available only at LMR.com. Pick one up today and get your motor back together with the correct parts!

Alternator Max RPM
The maximum Alternator shaft RPM is 16,000 RPM. This RPM is calculated by taking the crank pulled diameter and dividing it by the alternator pulley diameter. Then multiply it by the max engine RPM.

Underdrive Pulley Note
Charging performance is tested with stock size accessory drive pulleys. Underdrive pulleys will lower the alternator RPM thus preventing optimal charging at engine base idle speed.

Installation & Fitment Notes:

  • The alternator housing is slightly larger than your factory unit. Minor bracket clearance/modification will be necessary
  • The output will decrease when used with underdrive pulleys by up to 30%.

  • This alternator bracket is NOT pre-threaded and will require the use of a New Tensioner and a Threaded Tensioner Bolt for proper installation.
