Add to Wishlist


The Sikky Manufacturing Wiring Specialties Turn Key Swap Kit is the first of it’s kind on the market. If you have a S13 chassis, LS1 motor and T56 transmission then this is the kit for you!

The Sikky LSX swap kits are designed for use with the LS series of motors (LS1-LS9) and the T-56 transmission. Our kit requires no modifications to the factory cross member or subframe and does not hang below the crossmember when installed.  When using the Sikky kit it’s a direct drop in solution. The Sikky motor mounts are CNC machined billet aluminum versus the mig welded sheet metal mounts that other kit manufacturers provide. Our products are built to the highest standards. Every component offered in the kit was completely designed in house by our team of engineers from the ground up. Unlike our competitors that retro fit off the shelf bushings and other parts from different manufacturers, our urethane transmission and motor mount bushings are designed specifically for these applications. We build our oil pans with a 1/2″ thick flange and back plate to provide superior strength that will outlast and outperform other pans available. All our products are tested under rigorous track conditions to ensure our customers are provided only the highest quality parts available.
