I like the upper control arms but even with the Bilsteins, I was never happy with the ride so I recently lowered my truck. As far as the install, It is easy. The only problem you may come across is the UCA frame pockets might need a little spreading to accept the Cognito arms. Just put a board or something in there and spread them until the arms fit then when you tighten the bolts it will pull them back in nice and snug.:thumb:
