3003 000 6053 / 3003 000 2053. 056, 056 SUPER, 064, 066, 066 MAGNUM, MS 500i, MS 650, MS 660, MS 660 MAGNUM, MS 661 C-M, MS 661 R C-M. We recommend big chainsaw to match 36'' bar combo because his power is enough to run it. Even if my bar combo can install on some model such as 044 046 MS440 MS460 MS461 MS462 etc. But we don't recommend you use it because horsepower isn't enough to run 36'' bar. There Are Slight Difference Between The Picture And The Real Item Caused By Light Brightness, Hope You Can Understand.
