The Synergy 8 Inch Coil Spring Stretch Kit for 2 door JK's is a version of our 8 inch stretch kit that doesn't require converting to coilover shocks. The additions to the kit are coil spring relocation brackets and shock relocation brackets for use with our standard 8 inch rear stretch brackets for 2 Door JK's. This allows the Synergy 8 inch stretch kit to be used with standard coil springs. Allowing for standard coil springs takes much of the guesswork and tuning out of properly setting up a stretched JK. This also allows for more shock options, as it is easier to fit larger 2.5 inch shocks or even bypass shocks.

  • This kit cannot be installed using simple hand tools, it requires significant fabrication and welding skills to correctly install
  • TNT Customs 8 inch rear stretch corners are designed to work with this kit, part # JCA280 (with rear light pockets) or JCA280NL (no rear light pockets)
  • Due to the placement of the rear coil springs, rear coil springs should be two inches shorter than the front coil springs. We recommend 8063-30 front coil springs and 8064-10 rear coil springs for 37-40" tires.
  • Installation requires basic hand tools, grinder with cut-off wheel or sawzall, floor jack with jack stands or automobile lift, and a welder. Extensive cutting, grinding, welding, and fabrication skills are required to complete installation.
