Product Details

Overview & Technology

RockShox BoXXer Ultimate C2 200 Hour Service Kit (Part #: 00.4318.025.130, SKU 942529) is the OEM overhaul kit you need to refresh a 2020 BoXXer Ultimate C2 fork after extended use. This SRAM model FS-SVC-200H-A1 kit consolidates all wear items for the 200‑hour / 1‑year service interval: dust seals, foam rings, o‑rings, a Charger 2.1 damper sealhead and a DB air spring sealhead. The kit replaces elastomeric and wear-prone components with factory-specified parts: abrasion-resistant seal compounds, precision foam rings to maintain damping oil control, and machined sealheads that restore proper damping and air spring sealing. Small box, big impact — shipping dims: 6.3" x 5.3" x 1.1", weight: 0.2 lb.

Key Features & Benefits

Complete wear-item coverage: The kit contains dust seals, foam rings and o‑rings sized for the BoXXer Ultimate C2, eliminating the need to source parts individually. Replacing these items prevents oil leaks, contamination and the gradual loss of damping consistency. Charger 2.1 damper sealhead and DB air spring sealhead included — two high-wear metal/elastomer assemblies that restore smooth damper action and reliable air-spring pressure retention. The result is improved sensitivity, regained mid-stroke support and longer component life between services.

Fit & Compatibility

This kit is designed specifically for the 2020 RockShox BoXXer Ultimate C2 forks. Confirm compatibility by matching your fork model/year and the SRAM service ID FS-SVC-200H-A1. The parts are OEM-fit and follow RockShox tolerances for diameter and material hardness. Not all BoXXer model years or trim levels use the same sealheads or ring sizes — if you ride a different BoXXer generation, check your fork's service manual or contact Forest Bikes support to verify fit. This kit is intended for use during the recommended 200‑hour / 1‑year maintenance window.

Who This Kit Is For

Designed for gravity and enduro riders who put heavy mileage and aggressive demands on their forks, this kit is perfect for racers, shuttle riders and weekend riders who want consistent performance during a race season or busy summer. It’s a cost-effective way to maintain peak fork function without replacing major components. Mechanically inclined home mechanics will appreciate the straightforward parts set for a full lower-leg and damper refresh, while race teams and shops will value the OEM parts for warranty-friendly repairs and reliable aftercare between full rebuilds.

Frequently Asked Questions

What parts are included in this 200‑hour service kit?

The kit includes dust seals, foam rings, o‑ring seals, a Charger 2.1 damper sealhead and a DB air spring sealhead. These are the factory-specified wear items for the 2020 BoXXer Ultimate C2 required at the 200‑hour/1‑year service interval.

Is this kit compatible with other BoXXer model years?

This kit is specifically made for the 2020 BoXXer Ultimate C2. Some BoXXer generations or trims use different sealheads and ring sizes, so check your fork model/year or the service manual before purchasing. Contact Forest Bikes if you need help confirming fit.

Can I install this kit at home or should I go to a shop?

A competent home mechanic with the right tools and service manual can install this kit, particularly for lower-leg and sealhead swaps. However, installing damper sealheads and performing precise torque/bleed procedures often benefits from a professional shop to ensure correct reassembly and avoid damage.

How often should I service my BoXXer fork?

RockShox recommends a lower-leg service and basic refresh every 200 hours or annually, whichever comes first. Heavier use, muddy conditions or race seasons may require more frequent attention to prevent premature wear.

Does this kit include any lubricants or tools?

The kit contains replacement parts only — seals, foam rings and sealheads. It does not include suspension oil, grease or specialized tools. Plan to have the correct RockShox fluids and the appropriate tools or a shop service if needed.

Will installing this kit restore like-new performance?

Replacing seals, foam rings and sealheads will address common causes of leakage and degraded damping, returning much of the fork's original sensitivity and air-spring performance. If internal wear or damage is present, a full damper rebuild or parts replacement may still be required.

Buying Guide

When buying a fork service kit, prioritize OEM compatibility and the specific service interval your manufacturer recommends. Look for kits that include both lower-leg wear items (dust seals, foam rings, o‑rings) and any sealheads or cartridges that commonly wear on your model — replacing only some parts can leave other failure points unaddressed. If you're a DIYer, ensure you have the RockShox service manual, correct oil weights, seal drivers and torque tools. For peace of mind and warranty protection, many riders prefer having a trained suspension shop perform sealhead swaps and damper work.
