Shock Absorber Type 540 TS Suspension Kit

Ride comfort for Harley-Davidson Tri Glide, all model years

From the factory, the rear spring rate on Tri Glide models is too soft. The result is harsh bottoming over bumps and a choppy ride that transmits straight into the rider’s back.

Our Wilbers conversion solves this with spring struts tuned to the correct spring rate and matched rebound/compression damping. To balance the chassis, we also address the fork: stock forks are overly stiff relative to the rear, which causes an unharmonized feel—think nervous bars on rough pavement. Our Zero Friction fork springs correct this, improving initial response and overall balance.

Result: noticeably better comfort, control, and safety.
