Product Details

Overview & Technology

RockShox 8X41.5 rear shock mounting hardware is a compact, three-piece assembly engineered to restore secure, whisper-quiet connection between your frame and rear shock. Designed as an OEM replacement (Manufacturer Part #: 11.4118.091.842, SRAM Model ID: RS-SPP-A0), this kit gives the exact fit and function RockShox specifies for many modern mountain bike rear shocks. The kit uses precision-machined components finished for corrosion resistance and smooth articulation. Because the hardware is built to OEM tolerances, swapping worn or damaged mounting parts back to RockShox spec eliminates play, reduces noise, and protects suspension bearings—keeping your shock performing as intended under load.

Key Features & Construction

This is a true service part crafted for durability and dependable performance. The three-piece set includes a central shaft and matching spacer/bushing components that work together to maintain alignment through rough terrain. Components are machined to tight tolerances to minimize side-load wear and keep suspension action smooth. Real-world benefits: • Precision fit reduces slop and axle movement for crisper suspension feel. • Corrosion-resistant finishes stand up to mud, sweat and seasonal storage. • Lightweight design keeps unnecessary mass off the rear end of the bike—important for trail responsiveness.

Fit, Dimensions & Compatibility

The kit is specified as a 1/2" style three-piece mounting assembly with an 8X41.5 designation — intended as a direct replacement where RockShox calls for this exact hardware. Always check your shock and frame service manual for the correct part number; this item corresponds to RockShox / SRAM Model ID RS-SPP-A0 and Manufacturer Part # 11.4118.091.842. Shipping dimensions are compact (4.125" x 2.5" x 0.75") and the kit weighs essentially nothing in pack terms (0.01 lb), so it’s a convenient spare for service kits or a rolling toolkit. If in doubt, verify inner diameters and bushing styles against your existing hardware or contact Forest Bikes tech support with your shock model and serial number for fit confirmation.

Who This Is For

This mounting hardware is aimed at mountain bikers who service their own suspension or mechanics in shops who need reliable OEM parts. If your rear shock exhibits play at the eyelets, creaks under pedaling, or you’re replacing stripped/worn bolts after frequent travel, this kit restores factory securement and alignment. It’s also a smart buy for riders keeping a spares drawer for quick field repairs or for anyone doing a full suspension overhaul where replacing all mounting hardware is recommended to preserve bearing life and maintain precise suspension kinematics.

Frequently Asked Questions

What exactly is included in the 3-piece assembly?

The kit is sold as a three-piece mounting assembly that replaces the shaft and matching spacer/bushing components used to mount the rear shock to the frame. It’s intended to be a direct OEM-style replacement—check your existing hardware to confirm matching geometry before installing.

Will this fit my shock/frame?

This part is designed for applications specified by RockShox/SRAM under Model ID RS-SPP-A0 and Manufacturer Part # 11.4118.091.842. Confirm fit by comparing the part number against your shock service documentation or by measuring your current mount dimensions. If you're uncertain, provide your shock model to Forest Bikes support for confirmation.

Do I need special tools to install it?

Installation typically requires standard suspension service tools—hex keys and a torque wrench for the mounting fastener. For crush-sleeve or bushing installs you may need a soft-jaw vice or appropriate drift to avoid damaging finishes. If you’re not confident, professional installation at a bike shop is recommended.

Can I reuse my old spacers or bushings?

Reusing worn spacers or bushings is not recommended. These parts wear over time and can cause play or misalignment. Replacing the entire mounting assembly with this OEM kit restores correct tolerances and helps protect the shock eyelets and bearings.

Is this compatible with aftermarket shocks?

Compatibility depends on the shock eyelet diameter and intended mounting hardware spec. Many aftermarket shocks follow common standards, but always verify the shaft diameter and spacer length against the aftermarket shock’s requirements before purchasing.

Does this kit include the outer mounting bolt or nut?

This 3-piece assembly contains the core mounting elements as specified by RockShox. Specific included items may vary by SKU; check the product images and Forest Bikes parts notes or contact support if you require the full bolt/nut fastener set for your frame.

Buying Guide

When choosing shock mounting hardware, match the Manufacturer Part Number and SRAM/RockShox model ID to your shock and frame. Exact geometry — shaft diameter, spacer length and bushing style — matters more than brand. Using OEM-spec parts preserves the intended suspension kinematics and helps avoid premature wear on shock eyelets and frame mounts. Stock a spare kit if you frequently travel, race, or service your suspension. In workshops, replacing mounting hardware during a shock overhaul is inexpensive insurance against subtle misalignment and creaks that develop from worn components.
