Product Details

Overview & Technology

RockShox Shock Hardware 8X58.0 is a compact, 3-piece rear shock mounting kit designed to restore secure, play-free attachment between your frame and rear shock. The kit is supplied to RockShox/SRAM specification (SRAM Model ID: RS-SPP-A0, MPN: 11.4118.091.858) and sized for applications that require a 58.0 mm length mounting pin with a 1/2" seating interface. The components are precision-machined to tight tolerances to ensure concentric alignment of the shock eyelet through the frame linkage. A corrosion-resistant surface treatment and hardened pin construction minimise wear and keep pivot preload consistent ride after ride, reducing noise and bushing wear in your rear suspension system.

Key Features

What you get in the kit: a three-piece assembly sized 8X58.0 for 1/2" mounting applications. The typical configuration includes the mounting pin, a matching internal sleeve/spacer, and the retaining nut or cap — engineered to match RockShox mounting geometry and clearances. Real-world benefits: easy replacement to eliminate play and creaks, restores original factory spacing, and prolongs service life of shock eyelet bushings. The small footprint and low weight (0.1 lb shipping weight) make it unobtrusive but essential maintenance hardware for rear suspension setups.

Fit & Compatibility

This Shock Hardware 8X58.0 is intended for RockShox rear shocks and frames that use the 58.0 mm pin length and 1/2" seating diameter standard. Confirm compatibility by checking your shock's hardware code or the frame/shock service manual — the kit matches SRAM/RockShox Model ID RS-SPP-A0 and Manufacturer Part # 11.4118.091.858. If you're replacing worn or damaged hardware, measure the existing pin length and inner sleeve diameter before ordering. If your frame or shock uses built-in bushings or a different offset, consult our fit guide or customer service to avoid mismatches. When in doubt, bring the old hardware or exact shock/frame model to a mechanic for verification.

Who This Is For

This mounting kit is ideal for mountain bikers, mechanics, and workshop technicians who maintain RockShox-equipped full-suspension bikes. It's a must-have spare for riders who frequently service linkage bearings, swap shocks, or want to eliminate play and noise from the rear suspension. Whether you're a weekend rider replacing corroded pins or a shop performing a shock rebuild, the 8X58.0 kit provides a factory-spec replacement that keeps your suspension tracking as intended by the manufacturer.

Frequently Asked Questions

How do I know this hardware fits my shock or frame?

Check your existing hardware dimensions — the 8X58.0 kit is for a 58.0 mm pin length with a 1/2" seating interface and matches RockShox/SRAM Model ID RS-SPP-A0. If unsure, consult your shock or frame service manual or contact Forest Bikes with your shock/frame model for verification.

What parts are included in the 3-piece kit?

The kit contains the mounting pin, a matching internal sleeve or spacer, and the retaining nut/cap configured to RockShox specification. These three components restore the correct spacing and secure the shock eyelet in the linkage.

Do I need special tools to install it?

Installation generally requires basic workshop tools: appropriate hex/allen keys or sockets, torque wrench, and possibly a press for bushings if replacing them too. Follow RockShox torque specifications and use threadlocker only if specified by the manufacturer.

Can I reuse the old sleeve or should I replace bushings too?

If the sleeve or bushings show wear, corrosion, or ovaling, replace them. New hardware will seal and align best with fresh sleeves/bushings; reusing worn parts can lead to play and accelerated wear. Inspect bushings when changing pins.

Is this an OEM RockShox part or an aftermarket copy?

This listing is for the RockShox Shock Hardware 8X58.0 matching the Manufacturer Part # 11.4118.091.858 and SRAM Model ID RS-SPP-A0 — a factory-spec replacement designed for RockShox/SRAM systems.

Any weight or shipping dimension details?

Yes — shipping dimensions are 5.15" x 4" x 0.5" and the kit ships at approximately 0.1 lb, making it easy to carry as a spare on shop carts or in a mechanics kit.

Buying Guide

When buying rear shock mounting hardware, the two most important dimensions are pin length and pin seating diameter — both must match your shock and frame design. Look up OEM part numbers (RockShox/SRAM IDs) or measure the old hardware to ensure a direct replacement. Material and finish matter: corrosion-resistant and hardened materials will last longer under wet and muddy riding conditions. Also consider whether you need to replace associated sleeves or bushings at the same time. Worn bushings can make new hardware feel loose immediately; replacing both ensures the suspension performs quietly and precisely. If you're unsure, contact Forest Bikes with your frame and shock model and we'll help confirm the correct kit.
