Rockshox BoXXer Ultimate D2 Black Charger3.2 RC2 29" 52mm OS

The BoXXer Ultimate is RockShox’s flagship downhill fork, built for riders who demand maximum composure, traction, and control on the fastest tracks. Designed around a proven dual-crown chassis with 38 mm stanchions, the latest generation introduces the LinearXL air spring and Charger 3.2 damper to deliver a ride feel that closely mimics a coil fork while retaining the tunability and weight advantages of air.

At the heart of the fork is the Charger 3.2 damper, featuring intuitive high- and low-speed compression adjustment and revised rebound and compression tunes specifically matched to the LinearXL air spring. A new numbered control bezel makes setup simple and repeatable, allowing riders to start from a defined baseline and easily fine-tune damping on the trail or at the track.

The new LinearXL air spring provides a highly consistent stroke with supple initial sensitivity, strong mid-stroke support, and a jounce bottom-out bumper that adds extra control at full compression. Combined with RockShox’s ButterCups vibration-reducing technology and the new ButterWagonTech oil distribution system that keeps the bushings continuously lubricated, the fork maintains smooth performance and reduced friction throughout the service interval.

Designed specifically for downhill racing and aggressive gravity riding, the BoXXer Ultimate delivers the stability, damping control, and durability required for modern DH tracks and bike park terrain.

Tracking and Notifications

All outgoing parcels are tracked. Tracking details will be provided once the item has been dispatched. NSDynamics does not send arrival notifications for inbound service items unless the parcel is damaged in transit or missing important components required for service.

Customers are encouraged to use tracked and insured freight when sending items to NSDynamics. Responsibility for the parcel remains with the sender until the item is received and checked in at the NSDynamics workshop.

Shipping Fees

Return express postage back to the customer is included free of charge for all full Factory and Hyperformance service types. It does not apply to minor repairs or basic services. Shipping charges for parts or accessories are calculated during checkout.

Postage to NSDynamics is the responsibility of the customer unless otherwise arranged. Warranty items may qualify for return postage coverage only if they were originally supplied by NSDynamics and a clear fault is confirmed.

Shipping Insurance

All parcels sent from NSDynamics are covered under NSDynamics’ freight insurance. In the unlikely event that an item is lost or damaged during return transit, it will be replaced with a comparable item where possible. If a parcel arrives damaged, photo evidence must be supplied immediately. NSDynamics is not responsible for parcels where the receiver has chosen the 'Authority To Leave' option. 

Packaging Requirements

Customers must ensure that their suspension is packaged securely and appropriately for shipping. If an item arrives in packaging that is damaged or unsuitable for safe return, NSDynamics may use a heavy-duty branded box and apply a $5 fee to the final invoice. This ensures your suspension is protected during return freight. Customers are encouraged to retain and reuse this box for future service bookings.

Transit Times and Delays

While NSDynamics uses express freight to minimise delivery delays, transit times cannot be guaranteed. NSDynamics is not responsible for delays caused by freight carriers, public holidays, weather events, or other external disruptions. If a parcel has been delayed more than 5 business days beyond its expected delivery date, customers are welcome to contact NSDynamics for support.

Public Holidays

Unfortunately our workshop is closed on all nationwide and Queensland-specific public holidays, so we are not able to ship sales or service orders on these days. Any services or sales orders placed on public holidays will be processed and dispatched the following business day.

NSDynamics offers international shipping to New Zealand via Australia Post. Standard delivery times range from 5 to 10 business days. Customers are responsible for providing accurate delivery details and ensuring someone is available to receive the parcel.

It is the customer’s responsibility to be aware of local import requirements and costs. Orders returned, delayed, or destroyed due to unpaid duties or taxes are not the responsibility of NSDynamics.

In the event that a product needs to be returned from New Zealand, including for warranty inspection, all return postage costs are the responsibility of the customer. NSDynamics does not cover international return freight for items not originally purchased from NSDynamics.
