Franklin Performance LS alternator upgrade kit for Nissan RB engines.

Through clever design and demand from our customers Franklin Performance are proud to call this the best LS alternator upgrade kit on the market.

Compatible with all Nissan RB20, RB25, RB25 Neo, RB26 and RB30 engines, the kit will upgrade output from the factory 35-80A to 140A output using the modern LS alternator.

The kit features a unique tensioning system and a back side support brace to keep the alternator rigidly mounted to the engine - both features not found in our competitors kits.

All components are CNC machined from billet 6061-T6 aluminium and high tensile steel at our factory in Napier, New Zealand and are anodised or plated for great looks and durability.

The kit is supplied with all components and hardware required to fit, with the option to include a quality OEX brand alternator. Belts aren't supplied with the kits as there are many different combinations of water pumps & harmonic balancers.

Connecting the alternator is simple as the new LS alternator has the same connector & pin out as the factory RB engine alternator.
