Product Details

Overview & Technology

Restore your SID's performance with an OEM RockShox service kit. The 11.4310.703.000 kit contains precision-molded air seals, damper seals and the small hardware parts needed to rebuild the lower leg interface on 28mm SID forks from 2000–2008. Design and fit are factory-specified so you get the correct dimensions and tolerances for smooth, reliable operation. Materials and construction matter: the kit uses abrasion-resistant elastomer seals and purpose-matched hardware to maintain a reliable seal against stanchions and internal components. Correctly installed, these parts reduce oil leakage, lower friction (stiction) and restore consistent damping feel across rough terrain.

Key Features & Benefits

What you get: air seals, damper seals and the necessary retention hardware packaged together for a single lower-leg service. This OEM kit (SRAM Model ID: FS-SVC-A1, Mfg. Part #: 11.4310.703.000) saves you time hunting for the right pieces and assures compatibility with the original factory design. • Seals: precision-molded elastomer components for long life and low friction. • Hardware: correct-size clips and spacers where required to restore factory tolerances. • Performance: reduces stiction, prevents oil seepage and extends fork life when combined with fresh lubricant and correct service procedures.

Fit, Compatibility & What’s Included

This kit fits 28mm RockShox SID forks produced between 2000 and 2008. Confirm fit by matching the Manufacturer Part # 11.4310.703.000 or SRAM Model ID FS-SVC-A1 with your fork's service parts listing. The kit corresponds to RockShox part number 940377 for ordering and inventory purposes. Shipping and sizing: compact packaging (10" x 5" x 0.3") and lightweight (0.3 lb) makes the kit easy to store in a home workshop or pro service bay. Note: this kit services the lower leg/air and damper seal areas — for a full rebuild you may also need foam rings, oil and/or additional damper components depending on your fork's condition.

Who This Kit Is For

Geared toward cross-country and trail riders running older SID forks, home mechanics who maintain their own suspension, and bike shops servicing vintage or fleet bikes. If your SID shows oil around the lowers, increased stiction, or feel that’s inconsistent front-to-back, this kit delivers the exact OEM parts to bring the fork back to spec. Recommended user: riders who value precise fitment and OEM reliability — especially those who prefer to service their own forks or want a straightforward parts swap for common 28mm SID maintenance tasks.

Frequently Asked Questions

Will this kit fit my SID fork?

This kit is designed specifically for 28mm RockShox SID forks manufactured from 2000–2008. Verify compatibility by checking your fork model year and matching Manufacturer Part # 11.4310.703.000 or SRAM Model ID FS-SVC-A1. If in doubt, provide your fork serial/model to a Forest Bikes tech for confirmation.

What tools and supplies do I need to install this kit?

Basic suspension service tools are required: a set of metric hex keys, soft-faced mallet or seal driver, pick for removing old seals, cleaning solvent, and a torque wrench for reassembly of bolts. You'll also need RockShox-approved suspension grease and the correct fork oil if you plan to refresh damping fluids.

How often should I replace these seals?

Service intervals depend on riding conditions, but a common recommendation is lower-leg service every 50–100 hours of riding or at least once per season for regular riders. Replace seals immediately if you see oil weeping, excessive dirt ingestion, or increased stiction.

Does this kit include foam rings or fork oil?

No — this kit includes air seals, damper seals and the small hardware needed for the lower-leg interface. Foam rings, wiper cartridges and suspension oils are typically sold separately; check your fork’s service manual to determine any additional parts or fluids required for a full rebuild.

Can I install this at home or should I bring it to a shop?

Experienced home mechanics familiar with suspension service can install this kit at home. If you don’t have the proper tools or are unsure about disassembly/bleeding procedures, a pro suspension tech will ensure correct installation and prevent damage to stanchions or damping internals.

Is this an OEM RockShox part?

Yes — this is a genuine RockShox service kit, identified by SRAM Model ID FS-SVC-A1 and manufacturer part number 11.4310.703.000 (catalog/stock 940377). OEM parts ensure correct fit and material specification compared with generic aftermarket kits.

Buying Guide

When buying a fork service kit, match the kit to your fork’s stanchion diameter and model years — here, the 28mm SID spec and 2000–2008 production run are critical. OEM kits like this RockShox package are worth the extra cost for guaranteed fit and material compatibility. Decide whether you need a lower-leg seal kit only or a fuller service (foam rings, damping rebuild parts, and oil). If you plan regular maintenance, pick up the recommended grease and oils and stock a small set of suspension service tools — or factor in shop labor when budgeting.
