L83 / L86 Billet Accessory Drive System - Black - AC - PS - Alternator



Introducing a new GEN 5 “truck engine” L83 and L86 accessory drive system. This is a brand new design only available here.  This is an economical answer for those guys pulling these engines out of late model Silverado’s, and other Chevy trucks. Even though these are truck engines they are very similar in architecture to the LT1 engine found in high performance newer GM cars. These are aluminum engines that have direct injection, VVT and variable displacement, as their LT counterparts do, for an economical high performance answer for rodders looking for a cost effective solution.

Drive Junky has engineered this new design to allow these high tech, high performance engines to fit into older muscle car and truck frames.

Includes Type 2 power steering pump setup necessary for older vehicles. (modern gm engines use electric power steering)


-Automatic belt tensioner
-All stainless steel high strength hardware. 
-Sanden brand (not knockoff) ac compressor with custom one piece manifold to adapt to standard hose O ring fittings and all aftermarket AC systems, and billet AC pump cover.
-Aluminum power steering type 2 gm remote style pump for external mounted Power Steering reservoir. (customer supplied)
-Powermaster OEM style black 180 amp alternator (high quality finish only available here)
-Machined out of solid billet 6061 aircraft aluminum in large pieces. This is a big difference here, this utilizes heavier stock and machine away more material than other systems to minimize additional parts (spacers) to fit the parts better. This is much more expensive and labor intensive than the “plate and spacer” technology you see all over the industry.
-Accessories are easily removed for engine service, much thought has gone into this, we all work on our engines from time to time.

And of course this kit is entirely built and machined by us here in the USA!


INSTALLATION NOTE:  You will need to remove the factory vacuum pump on the lower drivers side of engine to run this accessory system. The power steering pump is mounted in that area shown in the photos.  Check your application but this part is mainly only needed on late model higher end trucks.
