The Jeep Wrangler is synonyms with the offroad. Since 1987, the Wrangler has been a staple for those backwoods, trail happy, off roaders and for good reason. The foundation of the wrangler is built on the CJ, the vehicle built by America to deliver some whoopins to the Germans in WWII. And out of the 4 generations of Wranglers, we’re going to focus on the PEAK wrangler, and that’s the TJ. Today we are going to break what makes the TJ so good, starting with it’s Quadra Coil 4-link suspension setup and then we’ll look at the beefy boy Dana axles that keep this wrangly boy rippin’ up those dusty trails.
Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

  • Everyone ragging on Jeep owners for not taking it off road, but overlook the very small percentage of sports car owners that actually take their car to the track........ I would bet that the percentage of Jeep owners that take it off road is much greater than the percentage of sports car owners that actually take it to the track.

  • thank you for teaching me about the different kinds of suspension. i’m 20yrs old and bought a 65 mustang. it has leaf spring suspension and bounces to much over railroad tracks and por holes. now i know what kind of coils to get and the benefits of doing so!!!

    LcwkeeLcwkeePrije mjesec
    • BigMateo24 will those really help? bc currently i have the issue of the back rear right side hanging a tad bit lower than the left, which results in my tire rubbing against the wheel well. my friend is currently fixing my engine and told me about this problem. i’m hoping it’s nothing serious like warping of the leaf spring or (please god no) the axel. so like, do you think the slapping bars will help? i’m also kinda broke bc of school and the car as is, so i need to know what to save for in the future so i don’t screw myself over.

      LcwkeeLcwkeePrije mjesec
    • Just get a set of slapper bars. They will help prevent axle wrap and are way easier to install then cutting off leaf spring brackets and welding on coil perches. Unless your going to back half the entire rear of the car and put an adjustable 4-link in it. Pretty 90's pro street but really effective on the drag strip.

  • I love the video and the channel just one thing I disagree with. I have an 84 CJ7 and I think it’s a little harsh on them labeling them as just “good”. I’ve taken stock CJs in places newer jeeps or 4x4s wouldn’t dare go CJs are so small and narrow they can really weave through right spots. Are they the best off road vehicle no but I don’t think it’s really fair to label them as last in the jeep lineup. With the right driver I would feel confident waging a CJ against most wranglers off road.

  • Ok well my 2002 wrangler is stock and has the death wobble. It will go away if tires are rotated every oil change after buying new. Looking out the windshield at 70mph watching the fenders violently bounce is not fun. Tap the brakes, let it coast and it will stop at 40 mph.

  • Did anyone else notice that they showed the stacking of the leafs wrong? They showed a large leaf closest to the axle and smaller leafs inside it towards the body of the truck. I believe in most applications the smallest leaf is against the axle in a spring over axle setup.
