I bought the front/ rear A-arm guards for my 2010 X2. The instructions were very limited. The front went on pretty easy but the rear was more difficult. The instructions fail to mention that you must remove the rear tires to fit the plates on. There is absolutely no way to install the A-arm guards on the rear without removing both rear wheels. Other than that, I highly recommend them. I purchased the silver bare aluminum look because they don't show marks or scratches. The hardware is solid and the torx bolts are high quality. These guards are great for hard core rock crawling.
Tough and well engineered A arm protection.
