Ditch that tired SR Alternator that is almost 3 decades old and step into a world of reliability. The alternators on the Nissan SR series engines came with an output of 70-90Amps.
The LS1 alternator itself are 1kg heavier when compared to the OEM unit due to the extra windings to produce a higher amperage output but overall the complete kit including the block bracket, adjuster and hardware are 1kg lighter inclusive of the 2kg weight saving of the PRP kit over OEM.
LS Alternators are 140amps
This kit can be installed in a short amount of time with ease and comes with:
- PRP Custom Billet Alternator Bracket
- PRP Custom Billet Block Adaptor Bracket
- Adjusting hardware to suit
- 20% Under driven Alternator Pulley to suit SR 5 rib belts
Kit is available in all PRP colours
