Fine-Tune Suspension Settings with XRAY 378040-O

For precise suspension setup, the XRAY 378040-O Aluminum Shock Preload Collar in bright orange is built for racers using the XRAY X12 and X10. This CNC-machined collar makes accurate shock spring preload changes fast and repeatable, helping dial in handling on varied track surfaces.

Precision Machining for Reliable Adjustments

Made from high-grade aluminum, the preload collar balances low weight with robust wear resistance. Its threaded profile lets you spin in exact amounts of preload so you can tune ride height and initial spring tension without guesswork.

Great for Racing Prep and Routine Servicing

Whether prepping for an event or doing regular shock servicing, the XRAY 378040-O helps protect shock longevity by keeping preload consistent. It is a practical upgrade for anyone focused on predictable suspension behaviour.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this collar fit shocks from other brands?

This part is sized for XRAY X12 and X10 shock bodies; other brands may use different thread or diameter so check measurements before fitting.

How does preload tweaking change handling?

Increasing preload raises ride height and initial spring rate, which can reduce squat and sharpen turn-in; reducing preload softens the initial response for more traction.

Any tips for installing the collar?

Lubricate threads lightly, run them down until the spring is seated, then set final preload with small incremental turns while checking ride height and shock travel.
