Easy installation. All bolt holes lined right up. Only problem was one small hex key bolt head located at the center of the armor stripped out before it reached the required torque . Will have to replace it with a stronger bolt. All riding is in the Sonoran Desert. Rocky as he** in most places. Hit a ton of large rocks and the chassis armor did its job. There is one small dent with about a 6" scrape about 1/16" deep in the armor now. Could have been my frame or engine case. Definitely worth the purchase.
