he addition of a larger aftermarket sway bar can increase the stress loads on the original OEM sway bar endlinks. To combat these increased loads, Racing Beat has designed a set of OEM style aftermarket endlinks for the front sway bar on the 2003-09 Mazda 3 application (except Mazdaspeed) to absorb the increased demands of a larger front sway bar. Incorporated into the design of these links are larger 12mm mounting studs and matching retaining nuts. The sealed bearing is self-lubricating and should offer many miles of maintenance free driving. These endlinks are intended for street and autocross applications and are highly recommended for use with the Racing Beat bar. Although these upgraded endlinks can be used with the stock sway bar, we believe that the original links are adequately suited for use with the stock bar. Due to the larger diameter studs provided on the Racing Beat endlinks, both the sway bar ends and the holes on the shock mounting flange must be enlarged to accept the endlink mounting studs. Provided in the endlink kit is the appropriate sized drill bit and a drilling guide to accomplish this task. Also included are detailed instructions complete with drilling suggestions and torque specifications. Note: The reason that the RB sway bar is provided with a 10mm hole is to allow use of the stock OEM endlinks. If we supplied the RB Sway Bar with a larger 12mm hole, then it would become mandatory to use the aftermarket links. Although the use of the RB Endlink Kit requires minor modifications, the rather cheap "insurance" offered by the installation of this kit is well worth the modest installation effort.
