Video: XT Explains Jeep Suspension Geometry


Suspension upgrades can affect the look, ride quality, off-road performance, and even the safety of your Jeep. Sure, a new 4” lift looks great, but what if it performs like crap? What if it wears tires prematurely? What if you have to replace universal joints every three months?

ExtremeTerrain (XT) wants your Wrangler to perform just as well as it looks, so Ryan Huck is back in front of the camera for their most recent Throttle Out video, “How Jeep Suspension Works.” “[I]f you really understand how the suspension geometry works [and] how the lift kit changes that geometry, you can make a good, well-informed decision,” Ryan explains.

A wide range of topics are covered including the track bar, Pitman arm, drag link, tie rods, control arms, sway bars, end links, pinion angle, driveshaft angle, caster, bump steer, roll center, body roll and potential causes of vibration. Great animations and a magnetic angle finder help him to explain all of the technical terms. Much of the information isn’t just Jeep-centric, but can be used for any four-wheel-drive application.

He sums it up with, “Hopefully, with this new information, you’ll be able to make a good decision when purchasing a lift kit as far as which components you want to make sure your lift kit includes.”

That restoration experience lead to pursuing a degree in Mechanical Engineering and a career in manufacturing. Since then, the garage has expanded to include a '67 Satellite, a '72 Scamp, and a 2010 Mopar '10 Challenger.
