Product Details

Overview & Technology

Keep your Domain B1 fork running smooth and predictable. This official RockShox 200-hour / 1-year service kit (SRAM Model ID: FS-SVC-200H-A1, MPN: 00.4318.025.190) contains the wear items you need to renew the air spring and lower leg sealing on Domain R and Domain RC B1 forks from the 2022 model year. Components include low-friction dust seals, closed-cell foam rings, precision O-rings and a DebonAir sealhead assembly. The seals are made from high-durability elastomers engineered to resist abrasion and oil swell, foam rings restore air-spring migration control, and the DebonAir sealhead brings the factory’s progressive air spring geometry and optimized seal interface back to spec.

Key Features & Materials

What’s in the kit: • Replacement dust/wiper seals — durable elastomer for long wear and low stiction • Closed-cell foam rings — restore proper air spring support and travel control • Precision O-rings — replace hardened or flattened seals to prevent leaks • DebonAir sealhead — factory air-spring sealhead to maintain DebonAir performance All components are made to RockShox OEM tolerances: elastomer seals formulated for oil resistance and abrasion, foam rings sized for exact air-chamber fit, and machined/assembled sealhead hardware designed to align sealing surfaces precisely. Installing these parts reduces stiction, eliminates slow leaks, and restores consistent ramp and mid-stroke support.

Fit, Compatibility & Part Numbers

Fitment: Specifically for RockShox Domain R and Domain RC B1 forks (model year 2022). This is the OEM 200-hour / 1-year service kit — do not substitute for other fork families without verifying compatibility. Official identifiers for ordering and confirmation: Product Number: 942730, Manufacturer Part #: 00.4318.025.190, SRAM Model ID: FS-SVC-200H-A1. If you’re unsure about fit, compare your fork’s model year and upper/lower casting details or contact our tech team with your fork serial number.

Who This Kit Is For

This kit is made for enduro and gravity riders who push Domain forks hard and follow recommended service intervals. If you race enduro, ride steep trails, or use your bike for aggressive all-mountain laps, replacing seals and the DebonAir sealhead every ~200 hours or 12 months preserves performance and prevents costly damage. It's also for home mechanics and pro techs who do routine suspension maintenance — a compact, OEM-quality service kit that contains all the common wear parts required for a standard lower-leg/air-spring refresh.

Frequently Asked Questions

What exactly is included in the Domain B1 1 year Service Kit?

The kit contains OEM dust/wiper seals, closed-cell foam rings for the air spring, replacement O-rings and a DebonAir sealhead assembly sized for the Domain R/Domain RC B1 (2022) forks. It covers the common wear items for the lower legs and air spring.

How often should I use this kit to service my fork?

RockShox recommends servicing these wear items approximately every 200 hours of riding or at least once per year, whichever comes first. Heavier use in muddy or abrasive conditions may require more frequent attention.

Can I use this kit on other RockShox forks?

No — this kit is engineered specifically for the Domain R and Domain RC B1 (2022) configuration. Other RockShox families (e.g., Pike, Lyrik, Zeb) use different seal geometries and sealheads. Always confirm compatibility via the SRAM model ID or part number.

Is this a DIY install or should I go to a shop?

Experienced home mechanics with proper tools (torque wrench, hex keys, suspension grease, isopropyl alcohol, clean workspace) can install the kit. However, if you’re not comfortable disassembling air-springs or don’t have the right tools, a qualified suspension tech will ensure correct reassembly and torque specs.

Do I need additional parts or fluids to complete the service?

You may need a small amount of suspension grease or seal lubricant, and possibly fork-specific lower-leg oil depending on the service scope. For a full lower-leg overhaul you may also need dust wipers and specific volume spacers — check the service manual for recommended consumables.

How can I be sure this is the correct part for my fork?

Check your fork’s model and year (Domain R / Domain RC B1, 2022), the SRAM model ID (FS-SVC-200H-A1), or match the manufacturer part number 00.4318.025.190. If you’re unsure, contact Forest Bikes with your fork serial or photos and we’ll confirm fitment.

Buying Guide

When buying a fork service kit, confirm exact fork model and model year — seal geometries, air spring components and sealheads vary across RockShox families. Choose OEM kits for precise tolerances and material compatibility; aftermarket seals sometimes use different compounds that affect life and feel. Also consider whether you’ll do the work yourself or use a pro: basic lower-leg and air-spring refreshes are manageable at home with the right tools, but full damper servicing or cartridge work is best left to trained techs. Keep a small stock of common service kits if you ride frequently in muddy or heavy-use conditions.
