Heavy Duty Clutch Bells for the Savage monster truck! Because these clutchbells are machined from a single piece of high-strength steel, they are much stronger than standard two-piece clutchbells. The clutchbell is clearly marked and is packaged individually. This clutch bell is a good hop up for the MT2 and Rush Evo models. For use on these models you will require 1 x B021 bearings in place of the B046 Needle Roller bearing.
