Platinum Racing Products - LS1 Alternator Conversion Kit for RB

Ditch that tired RB Alternator that is over 25 years old and step into a world of reliability. The alternators on the Nissan RB series engines came with an output of 35amps and 90Amps in the later model RB26. 

With today's technology and horsepower figures being constantly pushed, an average street car can easily consume even the full 90amps by making even the most minor modifications such as, Aftermarket ECU's, Additional Fuel Pumps, Upgraded Ignition Hardware or even a simple set of headlight upgrades.

Both our LS1 alternators in this listing from either OEX or GM/Mitsubishi produce a whopping 140amps and are a cheap viable upgrade for the RB platform using our quality conversion kit.

Platinum Racing Products has specifically designed this kit to eliminate the requirement of both alternator bracket and conversion bracket when upgrading to LS1 Alternators. Our kit comes fully integrated into ONE good looking and simple solution that allows your alternator to mount as close to the block as much as possible

This kit can be installed in a short amount of time with ease and comes with:

  • PRP Custom Billet Alternator Bracket
  • Adjusting hardware to suit
  • 20% Under driven Alternator Pulley to suit RB 4 rib belts, specifically designed to ensure not over spinning the Altenator beyond manufacturers recommendations. 
  • Optional LS1 Alternator (either OEX or Genuine GM/Mitsubishi [GM92058857])
  • Applicable to all twin and single cam RB engines.

If you are looking for a drive belt also we list the correct length to suit our LS1 kit along with an ATI Harmonic Balancer listed here.

Black mens coat
I didn't expect such good quality from such an inexpensive black coat, stylish, neat, looks expensive, none of my friends believed that I bought it so cheaply! No pellets appeared after a year and a half of use

Has shoulder pads.
The jacket has shoulder pads that don't necessarily show on the image in the purchase area. Pretty pronounced so if that's not your thing definitely stay away. Got lucky and it doesn't look too bad on me but it took so long to receive the package I don't feel like going through the refund process so I'm dealing with it. Quality is great tho
