    Notes
    • 4320-01, 4320-02 and 4320-03 have nylon outer shell.
    • 4324-01 and 4324-02 replacement bushings are only for 8550-01 and 8550-02 Track Bars who came with these bushings. If upgrading from 4306-01 polyurethane bushings, Dual Durometer Bushings (DDB) can be retrofitted one of two ways depending on bolt size: 
    • 94-07 trucks with 14mm or 9/16" bolt: Replace with 4323-01 Dual Durometer Bushing (DDB) or use 8529-01 Retrofit Kit
    • 08-13 trucks with 16mm or 5/8" bolt: Must use 8529-01 Retrofit Kit
    • 8550-01 track bars built 5/19/2015 and newer and 8550-02 track bars built 2/13/2015 and newer require replacement bushings 4324-01 or 4324-02 depending on bolt size.
    • 4322-01 bushing is not a retrofit for 8054 that came with Poly bushing halves. Correct replacement bushing is 4303-01 bushing halves.
