    This unit has the proper 300 psi nitrogen pre-charge and thread pitch and will function as original.  To help ensure proper replacement, HIGHWAY STARS just wants to take one step further, by including the CORRECT SIZE O-RING (as pictured), MADE WITH THE CORRECT COMPATIBLE RUBBER POLYMER FOR BRAKE FLUID APPLICATIONS.

    Our Brake Accumulator balls were recently produced "FRESH PRODUCT" with a RECENT DATE CODE. At Highway Stars, you don't have to worry about getting an old brake accumulator ball. We only sell the highest quality available.

    Product ships directly from Highway Stars warehouse, so you can be confident you are receiving the same HIGH QUALITY parts and service, as always from Highway Stars.

    This product MUST ONLY SHIP GROUND and will only ship within the US 48 contiguous states ONLY. If you order this with other products, your order may need to be recalculated according to Ground shipment requirements and shipment schedules.
