Our LS1 Alternator Conversion Kit for the Nissan RB. 

Ditch that tired RB Alternator that is over 25 years old and replace it with a reliable new Ls1 Alternator. The early RB alternators make 35amps with late model RB26s making 90amps.  

With today's technology and horsepower cars are easily consuming 90amps with simple upgrade. 

The GM/Mitsubishi LS Alternator produces 140amps making this an affordable viable option for replacement. 

With our Alternator kit this becomes an easy task. Positioning the alternator were it needs to be so you can go back to enjoying your car running with no worries about your alternator failing or not providing enough juice to run your electronics. 

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

2x Billet Alloy Brackets
1x Alternator Pulley
1x Fittings and fastenings required for the kit. 

Suitable for:
RB20 Engines
RB25 Engines
RB26 Engines
RB30 Engines
