Lifting a Wrangler and improving steering for off road and on road performance

Need a little extra room to fit those 35 inch tires?  Body lift and spring lift not enough?  So, the decision is down to coil conversion or spring over.  Worried about bump steer and axle wrap?

For the YJ, there is now an option - a spring over lift from Rubicon Express, High Steer System from Terraflex, and a Skyjacker 5th Link.

The box said “horsepower guaranteed”.  And, more important, it was CARB approved.  Finally, an air intake system for the pre-1997 Jeep Wrangler that was certified as emissions legal in California.  The air intake kit was K&N Fuel Injection Performance Kit for the 1991-1995 Jeep Wrangler with the 4.0L engine.

Murphy (if anything can go wrong, it will go wrong) and I are old acquaintances. I figured I had an afternoon and a Jeep (Just Enough Extra Parts).  Time to find some more horsepower.

This project started off like many others. "What if we could raise the engine a inch to gain some clearance and help out driveshaft angles?" Well, as it turned out it was easier said then done. The only one inch lift engine mounts on the market are for 4.0L YJ's and TJ's.

Jeep - a never ending story: Tires and Wheels

So, today was the big test. After many modifications, the Lil’ Heep was ready for the big test. Or, maybe just another step in the pecking order of modifications.

To set the stage, what started as a basically stock 1994 Jeep Wrangler with over 100,000 miles had undergone numerous operations en-route to its current configuration. Now set with 4.56 gears, front and rear locker, 4 inch spring lift, 2 inch body lift, 4:1 transfer case, NV-4500 transmission, and several other after market modifications, the Lil’ Heep was set to hit the trails.
