ZCI 7mm Solid Steel Bushings

These ZCI bushings are machined from steel instead of the common powder molding. Because of this, these bushings are just more durable in high load applications. The sinterd structure of the powdered bushings can collapse over time. These are a great choice for a normal build but especially good for the sector gear and when running very stiff springs. Because these lack the ability to trap any lubricants it's important you use a thicker lubricant with high pressure additives like a Teflon, molybdenum, or lithium soap grease.
