Saw these a few times and I finally found a source for them. These really help extend the life of your hiem joints (aftermarket steering setups) especially when you use it offroad and during the salty snowy winters we have here. Mud and salt kill them. I wear my rod ends out quick so with these protective boots and a little bearing oil I extend their life big time. These fit 3/4 and 7/8 rod ends. 15.99 for 2 plus shipping
