Alternators, Parts and Accessories:

This page covers everything related to the Alternator, including Alternator brackets, pulleys, voltage regulators, and of course the alternators themselves.

Bring your Mopar into the 21st century with our lightweight alternator and bracket conversion kit. This complete kit contains a modern, internally regulated lightweight and compact Denso 60 Amp alternator, as well as the mounting spacers, brackets and bolts necessary to retrofit this alternator onto your big block Mopar. And since these are internally regulated, you can simplify your wiring by getting rid of that factory firewall mounted voltage regulator. We even include the single groove pulley on the alternator! A nice clean looking setup that will make your car stand out from the pack... and at a great price! These fit all years and models of "B" AND "RB" wedge big blocks, as long as a 1968 or later water pump housing (or our aftermarket aluminum version) is used.

Part No: 109-1511 - Alternator Bolt Kit - Price: $12.95

Our ARP polished stainless steel alternator bolt & spacer kits are exactly what people mean when they say "show quality." Made from ARP's proprietary "300" stainless steel alloy, they are rated at a minimum 170,000 PSI, which is even stronger than a grade 8 bolt! And, you can't beat the quality, shine and corrosion resistance of polished stainless. Nothing resists the ravages of weather, time and even repeated tightening and loosening like stainless. These are truly maintenance free! Matching polished stainless washers are included. Considering these bolts are located at the front top of the engine, they're one of the first things you see when the hood is opened, so small details like this can really make a car "show quality." We even powder coat the spacers black for a finished look. Use these with the triangular style alternator bracket sets on our Alternator parts page.

No other vendor includes the CORRECT length bolts for this kit. Even ARP's pre-packaged complete engine bolt kits do not come with the correct length alternator mounting bolts. They are a custom made length, not available off the shelf. You can be assured that at 440 Source, we've done our homework, and you'll be getting the correct, factory original length bolts for this application.

Part No: 129-1034 - ARP Stainless Alternator Bolt Kit - Price: $26.95

We've also sourced the belts which work perfectly with our reproduction alternator and power steering brackets and pulleys. These quality belts are made by a division of Goodyear, (even though they don't have the "Goodyear" logo printed on them..

Part #138-1001 V-belt fits around the crank, water pump and alternator on all non-air conditioning big block cars. It works with the triangular alternator brackets, bolt and spacer kits listed above, and our reproduction non-AC water pump pulley (listed on our WATER PUMP PULLEYS page) and our reproduction non-AC crank pulleys (listed on our CRANK PULLEYS page.) It is used on cars with AND without power steering.

Part No: 138-1001 - V-Belt - Alternator & Water Pump drive - Non A/C -  NEW - Price: $14.95


Part #138-1002 V-belt fits around the second groove of our 132-1001 reproduction double groove crank pulley and goes directly to the power steering pump only. It is used as a second belt on power steering cars only, in addition to the belt/bracket/pulley setup listed above. 

Part No: 138-1002 - V-Belt - Power Steering drive -  NEW -  Price: $14.95

Shown above is our replacement "squareback" style alternator. These work with the 1970 & later style "dual field" electronic regulators. They can also be used with the '69 and earlier single field "points" type regulator if one field is connected to ground. These have a single pulley, so they are for non air conditioning (single belt) applications only. These are remanufactured in the USA. They work great with our brackets, belts, and bolt & spacer kits listed above. Some details in the appearance of the actual part may vary slightly from the picture.  

Part No: 118-1003 - Alternator - Dual Field / Single Pulley - Price: $49.95

Shown above is our brand new double groove alternator pulley. Gold irridite plated for good looks and corrosion resistance.

Part No: 120-1001 - Alternator Pulley - Double Groove - NEW . Price: $14.95

Shown above is our brand new dual field (electronic) voltage regulator. These were originally used on 1970 and later vehicles, and work with the "squareback" style alternators listed above. Two wires attach to this regulator. The one in the center (top of the V shape) gets attached to one of the "field" connections on the alternator and to 12 volts from the ignition switch, while the terminal on the right goes directly to the other field connection on the alternator. These are a great unit for updating earlier single field mechanical systems to the later style electronic.  

Part No: 120-1003 - Voltage Regulator - Dual Field Electronic - NEW . Price: $19.95

Chrysler first introduced their "new" aluminum lightweight alternators with the 1962 model year. From 1962-69, the alternator was part of a charging system which used a mechanical type of voltage regulator (the small rectangular style.) This regulator used mechanical points (similar to the points on a distributor,) which would open and close to help regulate the charging system voltage. This system uses one field wire (usually green in color) and is often called a "single field" system. The type of alternator used with this system can be easily identified by looking at the back. Shown above on the left, it is often referred to as a "roundback" style. The spade for the field wire can be seen at the 12 o'clock position with the letters "FLD" below it. We offer these alternators below in both single and dual pulley configurations. It is possible to use the dual pulley for the single pulley application, however the second pulley (closest to the radiator) will go unused. Usually non A/C cars will use the single pulley while A/C cars will use the dual pulley.

In 1970, Chrysler changed to an electronically regulated charging system. This system can be easily identified by the flat, square voltage regulator with a triangular plug on it. This is a much better, more reliable system that will keep the battery voltage more stable and is highly recommended for electronic ignition setups and aftermarket stereos/electronics, etc. This system uses two field wires and is often called a "double field" system. The type of alternator used with this system can be easily identified by looking at the back. Shown above on the right, it is often referred to as a "squareback" style. The spades for the field wires can be seen at the 2 o'clock and the 4 o'clock positions with the letters "FLD" next to them. Either wire can be hooked up to either field terminal, it makes no difference. Dual field alternators can also be used for single field applications if necessary by grounding one of the field wires. This will, in effect, turn the alternator into a single field unit. We offer these alternators below in both single and dual pulley configurations. It is possible to use the dual pulley for the single pulley application, however the second pulley (closest to the radiator) will go unused. Usually non A/C cars will use the single pulley while A/C cars will use the dual pulley. If you have the pre 1970 mechanical charging system and are not overly concerned with details of originality, we recommend converting to the newer electronic system.
