To ensure a proper seal and complete the bottom end, a full set of top and bottom end gaskets, seals, and O-rings are included. For your convenience, Wiseco also throws in an hour meter and bracket to help you keep track of maintenance intervals, plus assembly lube to get the job done right.

This kit is backed by a 90-day or 10-hour limited warranty against manufacturer defects, giving you confidence in your rebuild. Please note that this kit is not CARB approved and cannot be shipped to California.
