Pros: Bought these "used". Maximizes ground clearance as this unit is bolted through the tub. Has a 1/4" solid aluminum backer plate(s) that go inside the tub/passenger compartment that significantly increases the strength.
Cons: In addition to the conventional grade 8 bolts, to complete the installation requires the use of several nut-certs. Though many folks like nut-certs, they can be a PIA to install, and to later service the installation. That said. I can't think of an alternative to the nut-certs.
Comments: Currie Enterprises make excellent products, and these older style rockers are no exception to that. They're heavy, durable protection that provide piece of mind for me. I bought mine used. The ext time around I'll look into aluminum because of the weight advantage.
