Product Details

Overview & Technology

Genuine RockShox replacement: This Nylon Ball is an OEM service part engineered for the bleed piston sealhead on RockShox Monarch and Monarch Plus rear shocks. Manufactured to the original specifications (Manufacturer Part #: 11.4115.132.010, SRAM Model ID: RS-SPP-A0), the part ensures consistent fit and reliable function during shock bleeds and rebuilds. Made from high-strength, abrasion-resistant nylon, the ball is precision-molded to tight tolerances so it seats cleanly in the fixed-piston assembly. The result is a dependable seal that helps maintain consistent damping performance, reduces the risk of air or oil leaks, and keeps your rear suspension feeling factory-fresh.

Key Features & Benefits

Durable material and accurate sizing: The nylon construction resists swelling and deformation in hydraulic fluid and offers long service life under the low-speed movement of bleed pistons. Precision molding guarantees repeatable geometry for reliable sealing each service. • Sold as a 20-count pack — enough for multiple services or a shop stock. • OEM part number 11.4115.132.010 and SRAM ID RS-SPP-A0 for exact compatibility. • Small, lightweight replacement — shipping dims 4" x 4" x 0.3", weight 0.09 lb.

Fit, Compatibility & Installation Notes

Direct fit for: RockShox Monarch and Monarch Plus rear shocks that use the fixed-bleed piston assembly. This part is intended specifically for the Monarch/Monarch Plus family; confirm your shock model and service manual before ordering. Installation is part of routine shock service and rebuild procedures. Replace the nylon ball when you're rebuilding the bleed piston assembly or if you suspect wear or deformation. Use the RockShox service manual for torque specs and recommended lubrication — a thin coat of suspension-specific grease or assembly lube helps seat the ball and protects sealing surfaces during assembly.

Who This Part Is For

Frequently Asked Questions

What exactly does this nylon ball do in the shock?

The nylon ball acts as a sealing/seat element in the bleed piston (fixed-piston) assembly. When installed it helps form the intended hydraulic seal during low-speed piston movement, enabling consistent damping and preventing oil or air migration across the piston.

Is this compatible with all RockShox Monarch shocks?

This part is specified for Monarch and Monarch Plus models using the fixed bleed piston design. Check your shock's service manual or the part diagrams to confirm compatibility before ordering. If in doubt, provide your shock model and serial to our tech team for verification.

Can I install this part at home, or do I need a shop?

A competent home mechanic can install this part if they have the correct tools and follow the RockShox service manual. Tasks include disassembly of the shock end, correct seating of the ball, and proper lubrication. If you’re unfamiliar with suspension service, we recommend a pro tech to avoid damage or improper assembly.

Why buy the 20-pack? How many will I need?

The nylon ball is small and inexpensive but easy to lose or damage during service. The 20-pack is convenient for shops or riders who perform multiple services or want spares on hand. For a single rebuild you may only need one, but having extras avoids repeat orders.

Is this an OEM RockShox part?

Yes — this is a genuine RockShox part (Manufacturer Part #: 11.4115.132.010) and carries the SRAM model ID RS-SPP-A0, ensuring correct material and fit consistent with factory specifications.

Do I need any special grease or fluid when installing?

Use the suspension-specific assembly grease or lube recommended by RockShox in the service manual. These products protect sealing surfaces and help the ball seat correctly during assembly. Avoid petroleum greases not rated for suspension use.

Buying Guide

When buying shock service parts, always prioritize OEM components for critical sealing elements — they match original tolerances and materials. For RockShox Monarch and Monarch Plus shocks, check the service diagram or stickered part numbers on your shock to confirm you need the nylon bleed ball (11.4115.132.010 / RS-SPP-A0). Buy a multi-pack if you service multiple shocks or want spare parts between services. Pair this nylon ball with a full seal kit, recommended assembly grease, and the correct shock oil to complete a proper rebuild. If you’re unsure, consult Forest Bikes' tech team or a certified suspension shop to avoid mistakes that could harm performance.
