Twincam ILQ-9 Pro Bearings are designed for optimal performance using an exclusive 6-ball bearing design. Larger weight loads and less void in the bearing create a smoother spin with the SCRS (S-Channel Rubber Shield) system; TK racing gel (Made in the USA) lubricates the bearings.
What's the difference between ILQ-9 Classic & ILQ-9 Pro?
ILQ-9 Classic bearings are closed on both sides with a metal shield. The shield sits in an L-shaped undercut and is held in place by a removable C-clip. The undercut helps to form a protective barrier that keeps lubricants in and contamination out.
ILQ-9 Pro's are protected by a specially designed S-channel rubber shield. The SCRS presents an even more complex entry path for moisture and contamination. It is 95% effective at keeping the bearing clean. A nylon retainer on the inner face is shaped like a crown and is easy to remove and replace for servicing.
