"I want to commend JKS on the engineering of SUPERNERFS. I put a set on my 1995 Jeep ZJ and have never been so impressed by something so simple. Not only are they the only thing on the market specifically designed to protect rocker panels and doors, they are the strongest nerfs I've ever seen. I especially like the design in that they do not protrude laterally past the tires or vertically, more than about 3/4' past the pinch weld in the rocker panels. The biggest industry complaint on nerfs is that off roaders get hung up on the very thing they bought to protect their vehicle. That's not gonna happen with SUPERNERFS.

My ZJ had 184,000 mile on it when I installed the SUPERNERFS and you would not believe what they did to strengthen the unibody construction as well. You might as well have added a ladder frame to my Jeep. The squeaks, groans and rattles that disappeared is amazing. Thanks to all for a product and a job well done. If you need a rep in the 86404 area, I'm your man."
