Revtek makes Jeep and truck suspensions for 4x4s, 4x2s, and SUVs.

Average install time, according to the manufacturer, is under 2 hours, with no cutting or welding necessary. The kit is manufactured using aircraft-grade aluminum and specialty polyurethane.Contact: 877/543-8869; www.revtek.com

The XJ 4-inch lift shown here accommodates 32x10.50 tires, or up to 33x12.50s with fender cutouts. The system includes new coil springs, lower link arms, rear add-a-leaves, and Superide shocks. Standard or Rockrunner lower links are available, depending on how the Jeep is to be used. (Use Standard links for a "budget build" and/or if your Jeep rarely sees off-pavement use; optional Rockrunner links increase articulation.) An adjustable front track bar aligns the body with the front axle. The kit also includes bar quick-disconnects, transfer-case lowering kit to correct driveshaft angles, and replacement rear springs. XJs equipped with the NP231 transfer case may benefit from installation of a fixed-yoke conversion kit and CV-type driveshaft. Contact: 800/551-4955, www.superlift.com
The redesigned 4-inch long-arm system incorporates the Tera heavy-duty modular end assemblies and 1.75-inch DOM arms. The control-arm bracketry allows for easy installation and access to the transfer case without disassembly of suspension components. Sway-bar disconnects and a steering-box skidplate complete the system. The kit is said to fit all Wrangler models including the Rubicon and Unlimited. For custom applications with high-pinion, high-performance axles (Dana 60, T60R, CRD60R, et al), a custom component system can be assembled for your needs. Contact: 801/288-2585; www.teraflx.com
