This kit supplies four synchronizer plungers and four matching springs for rebuilding synchronizer assemblies in Mack and Volvo transmissions. Seated in the synchronizer hub, the spring-loaded plungers press the shift keys outward against the sliding sleeve to allow smooth gear engagement. The kit is sold as one complete set rather than requiring the pieces to be sourced separately.
