A few questions for you guys. Does the 189 kit include chains as well or is that just the upgraded tensioner parts? Are there assembly and reassembly instructions with the rebuild kit?
Does this kit imply that the OEM drivers side tensioner is up to snuff as is?
The $189 is the econo kit and only includes the billet portion (no chains) to assemble the tensioner using your original parts (easy, and yes, instructions are available)
The driver side tensioner correctly tensions the chain and does not require replacement.
