Product details
A heavy-duty replacement for your Honda's front suspension.
Bronco AU-04208 is a front gas shock for the Honda TRX650 / TRX680 Rincon, for the model years listed in the fitment table below. It combines a gas shock and spring in a ready-to-mount assembly, making it a practical choice when renewing a worn front shock.
Set the spring preload for your riding needs
Adjustable spring preload lets you set up the suspension for the load and use of your ATV. Bronco's heavy-duty shock range is supplied with springs that are 10% stiffer than standard. Preload adjustment is not a damping adjustment and does not change the spring rate.
Check the fit before you order
The 389 mm eye-to-eye length and the mounting dimensions below help you compare the replacement with your existing shock. Match the exact model, year and OEM reference; dimensions alone do not establish compatibility. Replacement eyelet bushings are available separately.
