Sikky Stage 3 packages are a master swap kit that includes a brand new wiring harness made by Wiring Specialties. This kit is ideal for those who want to buy an LS1 and drop it into their chassis with little left to do. The only pieces left to assembled are a fuel kit, intake, radiator and fans (coming soon from Sikky).


Fitment Notes:

  • 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.
  • Require some clearancing of the fire wall and trans tunnel to allow for fitment. This is fairly minor however and can be seen in our instruction manual listed on the instructions tab.
  • Removal of the factory front sway bar (or factory replacement) is required for oil pan fitment. We offer a custom sway bar for proper fitment and clearance – SIKKY S13 Sway Bar
  • Transmission and Shifter – This kit is designed to work with an LS1 style T56 transmission. This will allow the shifter to locate in the factory location. If you are interested in running a T56 magnum we also offer shifter relocation kits to help locate the shifter in the proper location. We can also accommodate you with the proper driveshaft as well for that application. The master cylinder kit we offer is required for proper function when using a T56 transmission.
