High Performance Alternators
High performance alternators are becoming more and more in demand as virtually everything on and off road is being equipped with more and more electronics. Elreg Distributors can supply you with the high performance alternator that you need whether it is for an EMS Vehicle, Fire Truck, Highway Coach, School Bus, Industrial Equipment, Marine, or Truck.
There are many manufactures of high performance alternators that Elreg Distributors is an authorized representative for – Delco Remy, Prestolite Leece-Neville, C.E.Niehoff, Hehr Powerline, Penntex, and EMP.
Delco Remy has their 40SI High Performance Alternator that is one of the most efficient alternators available. High efficiency means that more of your engine horsepower goes toward running the vehicle and less goes to powering the alternator. The 40SI is 70% efficient which when compared to a standard alternator equates to huge fuel savings. For a Line Haul Tractor 500,000 miles = $756 savings, for a City Tractor 350,000 miles = $372 savings and for a School Bus 250,000 miles = $1,057 savings. The Delco Remy 40SI14 volt alternator comes in 240, 275, & 300 amp J180-short, J180-long, and pad mounts.
Delco Remy also has their 28SI High Performance Alternator that is great for those demanding school bus applications. The 28SI can withstand extreme under-hood temperature demands of up to 257⁰F (125⁰C).The Delco Remy 28SI 14 volt alternator comes in 160, 180, &200 amp J180-short, J180-long, and pad mounts.
Both the Delco Remy 28SI and 40SI alternators come with remote sense. Remote sense prolongs battery life by ensuring that the batteries are kept fully charges. Due to many factors the voltage from the alternator drops by the time it gets to the battery. Just because the alternator is sending 14 volts doesn’t mean that the batteries are receiving 14 volts. With remote sense, a second wire reads the actual voltage at the battery, that’s coming from the alternator. It signals the alternator to boost its output to compensate for voltage drop and ensure that the batteries are getting 14 volts. This can reduce your battery charge time by 50%.
Prestolite Leece-Neville High Performance Alternators are equipped on many of the Fire Truck, EMS and Marine applications that require high amperage. Their 4860JB&4900PA Series alternators have models that produce anywhere from 185 to 320 amps at 12 volts. Regulator options include self-excite, ignition excite, and remote sense. These High Performance Alternators provide 50% of their rated output at 2,000 RPM (idle).
Prestolite Leece-Neville also has 24 volt 200 amp High Performance Alternators. Their 4740JB J-180 mount and 4964PA pad mount have self-exciting regulators.
Niehoff alternators areknown for their use in military, mining, construction, agriculture, EMS, marine, industrial, and transit bus applications. They come in both 14 and 28 volt and range in output depending upon your requirements all the way up to their High Performance 500 amp, 28 volt C803D.
Penntex manufactures many of the High Performance Alternators for the Ford early and late style E-Series & F-Series with 5.4/5.8/6.8/7.3/7.5L gas and diesel engines.Penntex also manufactures alternators for the GM & Chevy 7.4L gas, Duramax 6.6L diesel & 8.1L gas, 6.5L diesel. Their 12 volt alternators range in output from 175 to 350 amps. Penntex High Performance Alternators can be purchased as complete installation kits to convert your current system to a higher output and more reliable Penntex unit.
Elreg Distributorsis an expert in the field of supplying High Output Alternators for transit buses and coaches. Of course we can supply the Delco Remy 50DN and all of the related kits and parts to rebuild them.

There is the Penntex PX-833 – 24volt 330amp complete unit or the PX 8 BCK Conversion Kit that allows you to convert your own 50DN should you have the facilities to do so. You may also choose to use the Niehoff C-703 – 24volt 330amp option. If you are looking for more power Elreg Distributors can supply you with the EMP Power 450 which is a 24volt 450amp powerhouse! Finally if you want the ultimate in power there is the Niehoff C-803D 24volt 500amp alternator.
