Some manufacturers have eliminated this problem in the design of their kits' geometry, while others have solved the problem by offering optional CV driveshafts.

After the installation, those vehicles equipped with the Autotrac transfer case may encounter driveline vibration. Of course, this depends on which kit you're installing, how the manufacturer has approached the design, and the number of required components.ĭepending on the kit, you can plan on having to torch off frame brackets or differential brackets to make way for the new parts, and you may have to do some exhaust modifications to make way for the lowered IFS components. The common man, one who works on his truck in his driveway, will find that the first-time installation will take well over the 10-12 hours that most manufacturers indicate.

Mechanics who do these kits frequently tell us that once you do a few, it's possible to hustle through an installation in about six hours. Clearly, the GM IFS is a bit more complicated than a standard solid-axle/leaf-spring setup, and this is driven home when you look at what's involved in installing a lift.
