This is our 2007+ Chevy/ GMC under rail 3 link wishbone kit . Designed to allow you to run up to a 12" wide wheel and still have the capability of retaining the gas tank in the stock location.
We offer this kit in a few variations allowing the customer to choose whether they want to run full air ride suspension or a static set up with coil over mounts.
It is recommended that you run our raised gas tank crossmember (sold separately). With the raised gas tank crossmember, it moves the gas tank higher off the ground to help with ground clearance and it also moves the tank inward towards the driveshaft. This allows for better bag clearance.
When running air ride suspension , you will need to run a 2500 series airbag or a Slam RE6 or SS6.
