Description

RC Car & Truck Secret Weapon Ultra bearing 4 packs are specially designed for on-road or relatively clean driving environments. These bearings have stainless steel races, balls and retainers with ABEC #7 precision tolerances. The non-contact, Ultra seal eliminates most drag typically associated with a rubber sealed bearings and still provides extra protection against external elements. Bearings that are packed in grease will require a short break in period to loosen up. Grease can usually be removed before shipping upon request. KIT (4) SFR166-UU #7, (12x18x4) MM
