We got 2 sets of Ricochet's CV Boot Guards in last night via UPS. Got them installed on our Aces this morning. One set went on fine, the other...well, let's just say we had to go find longer bolts to install the rear set because the holes weren't drilled in the same place as the other set and we couldn't make the clamp with the threaded nut welded on align with the slotted hole in the boot guard! They also leave very little clearance on the rear guards between the guard and the wheel rim. They are made out of good, thick, aluminum but we felt Ricochet could have made them a little taller, both front and rear in order to give more protection to the boots. Better than the stock protectors, but not what we expected for what we paid for them. We like Thunderhawk CV Boot Protectors much better...guess we should have waited for them to come out with some. Just our .02 worth!
