Product Details

Overview & Technology

The RockShox Mounting Hardware 9.5x18.0mm (Part #11.4118.091.901, SRAM ID RS-SPP-A0) is a three-piece rear shock mounting kit engineered to deliver a precise, secure interface between your shock eyelet and frame. Sized at 9.5 mm diameter by 18.0 mm length and built to fit 1/2" style mounts, this hardware works with both imperial and metric shock eyelets for broad compatibility. Constructed as a sleeve plus two external collars/washers, the kit uses a corrosion-resistant finish on the steel sleeve for long-term durability and smooth articulation. The tight manufacturing tolerances minimize lateral play, protect shock bushings, and ensure consistent suspension performance ride after ride.

Key Features & Benefits

Precision fit: The 9.5x18.0mm sleeve is machined to OEM tolerances so the shock pivots without binding or excess play, preserving damper performance and reducing bushing wear. Durable construction: Steel sleeve with a corrosion-resistant coating plus two mating collars resist galling in wet and salty conditions. The three-piece design simplifies installation and replacement while protecting internal shock seals. • 3-piece kit: sleeve + 2 collars/washers for secure clamp • Compatible with imperial & metric 1/2" eyelets • SRAM/RockShox OEM part for direct replacement

Fit, Compatibility & Installation

This mounting hardware is intended for rear shock eyelets designed around a 1/2" pin interface and measures 9.5 mm in diameter with an 18.0 mm total length. It's compatible with most RockShox rear shocks and many aftermarket shocks that accept the 9.5x18.0mm sleeve size. Always confirm your shock and frame specifications or cross-reference the OEM part number (11.4118.091.901) before ordering. Installation is straightforward: press the sleeve into the shock eyelet, position the collars, and torque per your shock manufacturer's spec. Use proper press tools or a vice with soft jaws to avoid deforming the sleeve or shock eyelet; if in doubt, have a trained mechanic install it to preserve seals and alignment.

Who This Is For

This is for mountain bikers, mechanics, and home wrenchers who need an exact OEM replacement for worn or noisy shock mount hardware. If your rear shock develops lateral play, clicking, or accelerated bushing wear, replacing the hardware with this RockShox kit restores factory fitment and smooth articulation. It’s also a smart purchase for shops and builders stocking common mounting sizes—small, inexpensive parts like this keep repair times short and suspension performance consistent across trail, enduro, and all-mountain bikes.

Frequently Asked Questions

Is this hardware compatible with my RockShox rear shock?

If your shock uses a 1/2" style eyelet with a 9.5x18.0mm sleeve specification, this RockShox OEM kit will fit. Check the shock manual or existing hardware dimensions, or match the manufacturer part number 11.4118.091.901 to be certain.

Can I reuse my old sleeve or collars when installing a new shock?

We recommend replacing mounting hardware when installing a new shock if the original pieces show wear, corrosion, or deformation. New sleeves ensure proper preload and eliminate hidden play that can accelerate bushing and seal wear.

Do I need special tools to install this mounting hardware?

Installation is best done with a press or soft-jawed vice to avoid damaging the sleeve or eyelet. While a careful home mechanic can install the kit, shops use presses to ensure square, damage-free seating—if you're unsure, have a pro fit it.

How often should I replace shock mounting hardware?

Replace it whenever you notice play, noise, or rough articulation at the shock eyelet or after a crash that may have bent the sleeve. As routine preventive maintenance, inspect hardware during major service intervals and swap out worn parts to protect bushings and seals.

Is this a genuine RockShox/SRAM part?

Yes — this listing is for the OEM RockShox mounting hardware with manufacturer part #11.4118.091.901 and SRAM Model ID RS-SPP-A0, designed as a direct replacement for compatible RockShox rear shocks.

Will this work on non-RockShox shocks?

It will fit other shocks that specify the same 9.5×18.0mm sleeve and 1/2" eyelet interface. Always verify dimensional compatibility before using on non-OEM components to avoid mismatches.

Buying Guide

Choosing the correct rear shock mounting hardware starts with measuring the sleeve diameter and overall length from your existing kit or consulting your shock/frame manual. Match the OEM part number when possible; RockShox part #11.4118.091.901 (SRAM ID RS-SPP-A0) is the safest swap for compatible RockShox shocks. Prefer hardware with corrosion-resistant finishes and tight tolerances to minimize play and protect bushings. If you’re unsure about installation or your frame uses sealed or integrated hardware, have a qualified mechanic press the sleeve in to avoid damaging the shock eyelet or seals.
