Product Details

Overview & Technology

RockShox Shock Hardware 8X42.0 is a direct-fit, three-piece rear shock mounting kit designed to restore proper suspension alignment and eliminate play at the shock eyelet. The 8X42.0 designation refers to the 8 mm diameter x 42.0 mm overall length sizing; this kit uses a 1/2" (0.5") axle/shank standard used on many RockShox rear shocks. The kit is precision-machined for accurate tolerances and finished with a corrosion-resistant surface to withstand wet, muddy trail conditions. Designed and specified by SRAM/RockShox (SRAM Model ID: RS-SPP-A0, MPN: 11.4118.091.843), it replaces worn or damaged hardware to restore original articulation and reduce noise and lateral movement in the linkage.

Key Features & Construction

This three-piece kit features a low-friction insert and hardened sleeves to keep the shock mounted securely while allowing smooth rotation through the suspension travel. The construction focuses on durability and repeatable fit: precision sleeves, crush washers/spacers and a central axle that meet RockShox tolerances for shaft roundness and length. Real-world benefits: reduced play and rattle, consistent shock alignment for reliable damping performance, and simplified installation when servicing or rebuilding your rear shock or linkage. The compact kit ships light — 0.1 lb — and fits into standard shock service workflows.

Fit, Compatibility & Sizing

The Shock Hardware 8X42.0 is intended for RockShox rear shocks and linkages using an 8 mm bore with a 42.0 mm eye-to-eye mounting length and a 1/2" axle specification. Confirm compatibility by matching the 8x42.0 measurement and the SRAM Model ID RS-SPP-A0 or RockShox part number 11.4118.091.843 with your shock service manual or OEM parts list. Before purchase, measure the inner diameter of the linkage eyelet and the overall length of the existing hardware. If you run aftermarket linkage bearings or special bushings, verify clearance and stack height since this kit is sized to OEM RockShox tolerances. Shipping dimensions are compact (5.15" x 4" x 0.5"), making it an easy part to keep as a spares item for on-trail repairs or shop rebuilds.

Who This Is For

This replacement kit is for mountain riders, mechanics and home enthusiasts who need OEM-spec mounting hardware for RockShox rear shocks. If you hear knock from the rear end, notice side-to-side play at the shock eyelet, or are completing a shock service, this is the correct small-parts solution to restore precise suspension behavior. Recommended for trail, all-mountain and enduro riders who demand a rattle-free cockpit and consistent shock performance. Keep a spare set in your workshop kit — inexpensive hardware like this prevents premature bushing wear and helps maintain suspension reliability on long seasons of riding.

Frequently Asked Questions

How do I know this 8X42.0 kit fits my shock?

Check the bore diameter and overall length of your existing hardware: this kit is sized 8 mm x 42.0 mm and uses a 1/2" axle standard. Match the SRAM Model ID (RS-SPP-A0) or RockShox part number (11.4118.091.843) with your shock's parts list or service manual for a direct fit.

Can I reuse my old bushings with this hardware?

You can reuse bushings if they are within tolerance and free of damage, but worn bushings cause play and uneven wear. For best results replace bushings and seals during a shock service to ensure proper fit and longevity of the new hardware.

What tools and torque specs are needed for installation?

Installation typically requires basic suspension service tools: a press or soft jaws for sleeve insertion and appropriate split-pin or retaining hardware as specified by RockShox. Always refer to the shock manufacturer's torque and service instructions — improper fit or over-torquing can damage the shock or linkage.

Is this kit corrosion-resistant for wet conditions?

Yes — the hardware is finished to resist corrosion under normal trail conditions. Regular maintenance and cleaning will extend service life, especially if you ride frequently in salty or muddy environments.

Should I replace both sides at once?

It's best practice to replace mounting hardware on both sides during a service to maintain even wear and consistent suspension geometry. Replacing a single side can leave mismatched tolerances and allow premature wear on the remaining original part.

Is this an OEM RockShox part?

Yes. This product is specified by RockShox/SRAM and carries the manufacturer part number 11.4118.091.843 with the SRAM Model ID RS-SPP-A0 for direct OEM compatibility.

Buying Guide

When buying shock mounting hardware, the most important factors are diameter, length, and whether it matches your shock manufacturer’s specifications. Measure the inner diameter of the linkage eyelet and the overall length of the existing axle/sleeve assembly — common OEM sizes are stamped in the service manual or on the part itself. Match the SRAM Model ID (RS-SPP-A0) or manufacturer part number (11.4118.091.843) to ensure a direct-fit replacement. Consider replacing hardware as part of a full shock service (bushings, seals, and oil) to maintain correct stack height and minimize uneven wear. Choose OEM-specified or high-quality precision-machined kits like this RockShox 8X42.0 to preserve suspension performance and prevent knock, rattle, and premature bushing failure.
