After installing and driving for a while I decided to go back and write a review. they are cheap and easy to replace. The bipod arm is not properly made. Technically it matched, but not completely, and the angle was slightly off. That means the rack isn't parallel, so the steering is always off and can't align properly. The idler pulley itself was stiff and didn't absorb grease, so I just left the old one in place. The idler arm appears to be fine, but again the angle difference between the bipod light arm and the steering arm means it was not possible to get everything parallel which is required for correct steering alignment. Overall I would not recommend this product.
