Things Chrysler did a great job on with the TJ

Lately I've been thinking about the sheer number aftermarket mods out there for our Jeeps, and how often they don't offer functional improvement over stock. Very often, they're even detrimental to function. I'm starting to think that Chrysler engineers may have known what they were doing, after all.


Take the front bumper for example:
  • Very lightweight (only 7lbs, I believe)
  • Maximizes the approach angle/clearance (when trimmed to be stubby)
  • Bottom edge hugs frame crossmember for strength
  • Very easy to add a winch
  • Built in recovery points
Most all aftermarket bumpers will have some cons to the factory bumper, be it added weight or bulkiness.


Or say the stock transfer case skid. I hate the "shovel" as much as the next person, but it does offer a very impressive strength to weight ratio (only 40 lbs I believe). Many of the aftermarket skid are double that weight, with questionable strength increases.

Then there's the factory front fenders that take up most all the space available. There is no actual aftermarket upgrade out there, that doesn't require extensive reworking and cutting. And the list goes on and on with the factory soft tops, engine/transmission mounts, etc.


Curious if people have noticed any other areas where Chrysler did a great job at, whether due to superior design, better materials or other.

Suspension. 4" up and 4" down wasn't trivial even in 1997. The OEM control arm that can flex and twist is a nicely engineered design.

All the specialized fasteners they used in different places.

The factory wheel designs were beautifully matched to the design language of the vehicle.
 
Something we probably take for granted now, but wasn't it the first domestic 4x4 with coil springs in all 4 corners?

At least they used the front suspension designed by AMC , and kept the 4.0 . Also they used the AX -15 5 speed Transmission, which was much better than
what was available at the time.

Funny, every now and then I think about changing the front bumper and then ask myself “Why, it has everything I need, small, lightweight, recovery is there, and winch fits nicely”, then decide no reason to change it out.

30 years ago my dad had The guys make the below bumper for my YJ. It mounted over the bumper through the frame. I kept it all these years. When my son got his JK he sanded / cleaned / and painted it and installed it on his Jeep. You can’t see from the picture but the 1/2” steel plate angles down the face between the two verticals. We added the 1/4” flat stock across the front to hide the frame. The top holes didn’t line up really well on the top so took some angle and welded to the underside and mounted sideways through the frame.

About a 18 months later I picked up the LJ and sort of wish I had it on the LJ. This thing is stout.

It would also been nice if they would have had a option for electric windows. But another great thing about them was they were 100% owned then.

Guess that would be nice option, though I wouldn’t choose it. I like the simplicity of no wires to disconnect when removing the doors. While simple to do on the JK it is just one less thing to do / break. Though I do miss electronic locks 😂

The TJ's revolutionary suspension was the reason for the TJ's success in my opinion. After driving a "Jeep" while I was overseas in the military I knew I wanted one despite it not being good at faster speeds. I test drove new YJ Wranglers several times in the 80's and early 90's but they weren't suited or rode well enough for my daily driver needs especially since I wore a suit every day. Then the TJ came out and bought one right after my test drive 5/96. I was surprised how well it drove, rode, and handled.

My bumpers don’t have built in recovery points… which stock bumper (other than the AEV) had built in recovery points?
