Horrible Customer Service!!! Great Kit.

The Rancho suspension kit is of the utmost quality. When coupled with RS9000 shocks, this kit provides better than new ride quality. Expect 5-5.5" of lift. As for customer service and product delivery, it amazes me that this company can even be in business!!! I have never EVER experienced anything that paralleled this level of incompetence. It took over 10 phone calls just to find my order. Without my persistent efforts, this order NEVER would have arrived. I will never use 4WP again unless I can walk out of the store with the product in hand.
