🔄 Supersession & Cross Reference

OEM Supersession Chain

• 42953A7 is the Tracker graphite-grey assembly
• 42953A5 is the related black colour version
• 42953A6 is the related standard-grey colour version
• The A5, A6 and A7 parts are colour variants within the same bracket family rather than a linear supersession chain
