While the Wrangler Unlimited 4-door gets most of the attention in the ExPo forums, the 2-door JK is used for some interesting projects, too. Case in point, the Avenger Top Jeep by Avenger Supercharges in Colorado Springs:
The half-cab top creates an extended cab for two seats. No body trimming is required to mount the top. The tonneau cover provides covered storage.
This project includes 37 inch tires, a 3 inch lift, raised fenders, and trimmed frame rails to increase clearance front and rear.
The real reason for the project is to draw attention to Avenger's new supercharger for the 3.7L V6. Use it to achieve Hemi V8 power ratings for about $4500.
