TAARKS LS1 140a alternator upgrade kit.

Our kit is designed to bolt the Early LS1 ( AC Delco # 92058857 ) 140a alternator onto the SR20 rear wheel drive engines.

These alternators are a must when running larger fuel pumps, thermo fans, stereo systems etc.

The brackets are machined from billet 6061-T6 aluminium and anodised to prevent corrosion. Our unique adjuster allows easy adjustment of the belt without fear it might slip like other designs. Kit retains factory alternator location and the standard SR20 alternator pulley is to be used.

Use the drop down box above to select your colour and if you require a belt and alternator.

The kit includes:
1x Lower Alternator Bracket (use drop down box above to select colour)
1x Upper Alternator Adjuster (use drop down box above to select colour)
1x Adjuster Insert
1x Billet Aluminum Pulley (use drop down box above to select colour)
1x Stainless Steel Hardware kit

Easy Install

By: on 12 May 2021
Fairly easy install. Took close to 5 hrs to put it all together. There was a slight issue with the grounding cable, as the stock alternator uses a m6 bolt, but the LS alternator needs a m10 bolt to ground it onto the alternator itself, thus the ground wires needed to be re-crimped onto a larger lug to suit a M10 bolt. Apart from that small wiring hiccup, the install was easy and smooth.

LS1 alternator upgrade for SR20

By: on 21 October 2020
Great bit of kit. My SR has a heap of the Taarks gear on it and everything is really good fitment! My on suggestion would be providing information and/or parts for the earth. Looks like the LS earth bolt is somthing like an M8 whereas the stock SR is M5.

Fits great

Purchased the bracket kit only, and it works great! For the stock crank pulley, a 5PK970 belt is too long (belt was purchased elsewhere) - awesome bang for buck upgrade. Thanks Taarks
