This is a complete air conditioning and heating system for your Jeep CJ with a 4.2 liter inline six cylinder engine with V-belts. The 4.2 Liter six cylinder was used on CJ's and Wranglers from 1980-1990, this bracket will fit the 258 or the 4.2 liter in the CJ's.

This is a complete air conditioning kit that will add A/C and heat to a CJ. If your CJ has a faulty heater, or no heater this is the kit to replace all the old parts under the dash. The kit requires the removal of the entire heating system that is behind the dash. The kit is designed to work with R-134a refrigerant. The defrost is a diffuser that is added to the evaporator heating unit to allow the duct hose to run to the original defrost outlets.

The kit can be installed in one day, and includes all the necessary parts except the refrigerant to charge it, and the heater hoses. This A/C system is the most complete available in the aftermarket, and is guaranteed to be the highest quality. Please keep in mind that the under dash is a universal style unit that may require additional modifications to the brackets to secure it under your dash.
