Product Details

Overview & Technology

RockShox Shock Hardware 8X50.0 Offset is a compact, purpose-built rear shock mounting kit engineered to meet Trek frame specifications and RockShox service standards. The 3-piece, 1/2'' design carries the SRAM model ID RS-SPP-A0 and manufacturer part number 11.4118.091.850, making it a direct replacement for compatible rear suspension linkages. This kit uses Trek-specified aluminum for a balance of low mass and long-term durability, finished with a corrosion-resistant surface to withstand mud, water and year-round trail abuse. The precise offset geometry preserves shock eye-to-link alignment, reducing bind and keeping your suspension working smoothly through the travel curve.

Key Features

Built to perform: The 8X50.0 offset specification and 1/2'' bore are machined to tight tolerances so the hardware seats reliably in Trek linkages and RockShox shocks. The three-piece kit gives service techs the components they need for reinstall or replacement without adapting non-OEM parts. Real-world benefits include consistent bearing alignment, minimized lateral play, and a lightweight package that won't upset sensitive rear-end kinematics. Small details like the corrosion-resistant finish and compact packaging (5.1" x 4" x 0.5", 0.1 lb) make it practical for workshop drawers or trail-side spares.

Fit & Compatibility

This kit is intended for Trek frames and RockShox rear shock linkages that require an 8X50.0 offset mounting solution. Confirm compatibility by matching the SRAM model ID RS-SPP-A0 or the manufacturer part number 11.4118.091.850 with your bike's service manual or existing hardware. The 3-piece, 1/2'' specification refers to the kit makeup and mounting bore size used on many Trek-RockShox pairings. Always verify your frame and shock pivot measurements before ordering: check the eyelet inner diameter, overall offset, and stack dimensions. If your frame uses external bushings, bearings, or spacing shims, reuse or replace those components according to Trek or RockShox service recommendations to maintain intended geometry and torque specs.

Who It's For

Designed for mountain bikers, mechanics, and independent shops who need a direct OEM replacement for Trek-compatible rear suspension mounts. It's ideal for riders performing routine shock service, pivot rebuilds, or repairing damage from crashes. If you value precise suspension alignment and prefer OEM-spec parts to keep your bike handling as designed, this RockShox 8X50.0 offset hardware is a practical, lightweight choice that keeps your rear suspension behaving predictably across varied trail conditions.

Frequently Asked Questions

How do I know this will fit my bike?

Match the SRAM model ID RS-SPP-A0 or manufacturer part number 11.4118.091.850 to your bike's parts list or the hardware you're replacing. Also confirm the 8X50.0 offset and 1/2'' bore dimensions in your frame or shock service manual before ordering.

Are bushings or bolts included with the kit?

This listing is for the 3-piece shock mounting hardware kit. Depending on your application you may need to reuse existing bolts, bushings, or spacers. Check your bike's service documentation or existing hardware to determine what additional parts are required.

Can I install this at home or should a shop do it?

A competent home mechanic with basic tools can fit this kit, but installation should follow your frame and shock manufacturer torque specs and service procedures. Use a torque wrench and proper alignment tools; if you're unsure, a certified shop can ensure correct installation and prevent damage.

How often should I replace shock mounting hardware?

Inspect mounting hardware regularly for play, corrosion, or wear—especially after crashes or heavy use. Replace if there is any noticeable movement, scoring, or if tolerances have opened. Frequency depends on riding conditions; a good rule is to check at each major service interval or every 6–12 months.

Is this an OEM RockShox part?

Yes. This kit carries RockShox part references and the SRAM model ID RS-SPP-A0, making it an OEM-level replacement intended for compatible Trek frames and RockShox linkages.

Buying Guide

When buying shock mounting hardware, confirm three key measurements: mounting bore diameter, offset specification, and the part/model ID. OEM matching using the manufacturer part number or SRAM model ID ensures the kit maintains the frame's designed geometry and suspension performance. Consider material and finish—aluminum kits balance weight and strength while corrosion-resistant coatings extend service life. Also decide whether you need a full-service kit that includes bushings and bolts or just the mounting sleeve assembly. If in doubt, consult your frame or shock service manual or bring your bike to a qualified mechanic to avoid mismatched parts and preserve handling integrity.
