Motorcycle Shock Spring Preload Adjuster Bottom

Spring Preload Adjuster Bottom

Motorbikes change weight more than cars - an empty sedan versus one full of people & cargo might be say 25% heavier - but a naked bike and one with a heavy rider & riding gear plus full tank of fuel might double in weight. Your factory motorcycle dampers need more sophistication; if you have damping adjusters read our suspension setup tips to get the most out of them. The most common solution for changing the pressure on the shock coil spring is a pair of large locking nuts which screw up and down the threaded damper body.

Lower preload rings for setting rider sag and preload height

• Set preload height precisely - these are the lower rings that determine ride sag and spring tension.
• Lock in preload - lower rings are held by the upper locking nut to prevent movement under load.
• Easy adjustment options - rotate with a hooked spanner or fit a mechanical preload adjuster for socket access.
• Upgrade path - if preload limits are reached, choose a different spring rate; see suspension spring choice and Shock Springs & Hardware.

Recommended Pairings

Consider matching preload collars with specialised tools such as Suspension Tools and hooked spanners for safe adjustment.
