Product Details

Overview & Technology

RockShox Monarch AutoSag Full Service Kit (Part #11.4418.002.010 / SRAM ID RS-SVC-A1) supplies the genuine replacement seals and components needed to fully service a Monarch rear shock equipped with the AutoSag Specialized B1 system. This OEM kit is engineered to RockShox factory tolerances so each rubber and polymer component fits precisely and restores the shock to like-new performance. Why it matters: worn seals and hardening foam rings cause oil leaks, degraded damping and inaccurate sag readings for AutoSag-equipped bikes. Replacing these small parts with high-quality polyurethane and nitrile components prevents contamination, stops oil migration and keeps the AutoSag sensors operating correctly.

Key Features & What’s Included

This full service kit includes the specific seals, O-rings, foam ring(s) and small replacement parts required for a comprehensive rear shock service on Monarch AutoSag B1 units. Components are manufactured to OEM RockShox specs and use durable materials designed for long life under suspension loads and exposure to grime. • OEM parts: RockShox genuine seals and hardware for perfect fit. • Durable materials: polyurethane and nitrile rubber components resist abrasion and swelling. • AutoSag-specific parts: components that preserve sag calibration and sensor operation.

Fit, Compatibility & Specifications

This kit is formulated for RockShox Monarch rear shocks fitted with the AutoSag Specialized B1 system. Confirm compatibility by checking the SRAM Model ID RS-SVC-A1 or the manufacturer part number 11.4418.002.010. Shipping size is compact (6" x 5" x 0.4") and light (0.07 lb), making it easy to stock in a workshop or take on the trail for planned maintenance. If you’re unsure whether your shock uses the AutoSag B1 configuration, check your shock body stamping or owner’s manual — when in doubt, contact Forest Bikes or your local RockShox dealer with your shock serial for a match. This kit is intended for service procedures that include seal replacement and inspection; suspension oil and specialized tools are sold separately.

Who This Kit Is For

This kit is aimed at mountain riders who own or service bikes with RockShox Monarch rear shocks using the AutoSag Specialized B1 setup. It's ideal for experienced home mechanics, independent bike shops and race teams who perform periodic shock maintenance to maintain performance and reliability. If you value consistent sag settings, predictable damping and leak-free performance, replacing wear items with an OEM service kit is an affordable way to extend shock life and keep your bike handling as intended.

Frequently Asked Questions

What exactly is included in the Monarch AutoSag Full Service Kit?

The kit contains the seals, O‑rings, foam ring(s) and small replacement parts required for a full service of the RockShox Monarch with AutoSag Specialized B1. It provides the wear items needed to replace aged rubber and foam that cause leaks and degrade performance.

Will this kit fit all Monarch shocks?

No — this kit is specific to Monarch rear shocks equipped with the AutoSag Specialized B1 configuration. Verify fit by checking the SRAM Model ID RS-SVC-A1 or the manufacturer part number 11.4418.002.010 before ordering.

Do I need any special tools to install the service kit?

Basic suspension service tools are recommended, such as shock clamp, seal driver, pick tools and torque wrench. Some procedures require RockShox-specific tools and correct suspension oil; if you’re not comfortable, have a trained shop tech perform the service.

How often should I replace these parts?

Service intervals depend on riding conditions, but a general guideline is to perform a lower‑leg/service interval every 50–100 hours of riding or annually. Inspect seals and foam for wear and replace sooner if you notice oil seepage or poor damping.

Does the kit include suspension oil or lubrication?

No. The service kit supplies replacement seals and components only. Suspension oil, grease and any specialty fluids required for reassembly are sold separately — follow RockShox service manuals for correct oil types and volumes.

Can I use this kit to calibrate AutoSag myself?

Replacing the AutoSag‑specific components helps maintain sag accuracy, but calibration steps for AutoSag involve setting rider weight and checking travel measurements after reassembly. Follow the AutoSag setup guide or consult a technician if unsure.

Buying Guide

When buying a rear shock service kit, always match the kit’s model ID and part number to your shock. OEM kits like this RockShox Monarch AutoSag kit include the exact seals and small parts designed for the unit — aftermarket substitutes can fit but may not match material or tolerances. Plan your service by ordering any required suspension oil, specialty tools and replacement bushings at the same time. If you lack the correct tools or experience, budget for a shop service to ensure correct assembly, torque and sag calibration.
