The TeraFlex S/T sway bar crossmember bushing locates and centers the S/T torsion sway bar in the crossmember. This bushing is designed to fit the smaller trail rate torsion bar, and has an inside diameter of 1.5 inches. The sway bar bushing is molded from Nylatron GS. This material is a nylon and molybdenum disulphide (MoS2) composition designed with integrated self-lubricity to dramatically extend component service. The bushing can be used with little or no grease, but long term durability will increase with the use of a synthetic grease.Fits: 07-Present Jeep Wrangler JK 07-Present Jeep Wrangler Unlimited JK Details: 1.5 Inch Inside Diameter Molded From Nylatron GS Sold Individually
