PRP LS1 Alternator Conversion Kit - Nissan RB20/RB25/RB26

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.

Our LS1 alternator kit is designed to fit the GM 92058857, and with genuine units being discontinued, we offer a high-quality JAS equivalent. Producing an impressive 140 amps, this alternator is a cost-effective upgrade for the RB platform when paired with our premium conversion kit.

Beyond performance, the JAS units feature a sleek black finish and now incorporate a balanced shaft assembly, making them perfectly suited for high-RPM applications.

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 Alternator beyond manufacturers recommendations. 
• Optional JAS LS1 Alternator
• 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.
