Product Details

Overview & Technology

Genuine RockShox OEM damper shaft assembly designed specifically for the Deluxe Select+ C1+ rear shock platform (2023 and later). This replacement assembly includes the shaft, poker and lock piston delivered to factory tolerances so your shock performs like new after a rebuild. The assembly is precision-machined and heat-treated for strength, then finished with a corrosion-resistant surface treatment to resist wear and contamination in wet or muddy conditions. The tight tolerances and factory spec parts restore consistent damping performance and reliable lockout function on modern RockShox rear shocks.

Key Features & Benefits

Complete damper assembly: includes shaft, poker and lock piston so you have the parts needed to replace the worn internal components that cause inconsistent damping or leak paths. Using the full OEM assembly avoids mate-fit issues common with mixed aftermarket parts. Real-world benefits include smoother stroke feel, restored lockout precision, and longer service intervals thanks to restored sealing surfaces. The corrosion-resistant finish and heat-treated shaft reduce scoring and fatigue during heavy riding or long-term storage.

Fit, Measurements & Compatibility

This damper shaft assembly is made for RockShox Deluxe Select+ (C1+) rear shocks from 2023 onward. Available in three service lengths to match your shock internals: 37.5–45mm, 47.5–55mm, and 57.5–65mm. Confirm the correct length by checking your shock service manual or measuring the damaged shaft before ordering. Part number and identifiers: Product #943243, Manufacturer Part #11.4118.111.451. Shipping dimensions are compact (5.2" x 5.2" x 1.5") and the assembly is light (0.1 lb), making it easy to keep as a service spare or include with a full rebuild kit.

Who This Is For

Designed for mountain bikers and home mechanics who demand genuine OEM replacement parts for their RockShox rear suspension. If your Deluxe Select+ shock exhibits inconsistent rebound/compression, poor lockout engagement, internal scoring or fluid contamination, this shaft assembly is a frontline repair part to restore performance. Recommended for technicians doing a damper-level rebuild or for riders who want to maintain peak shock feel and reliability on trail, enduro stages, or all-mountain rides. Pair it with fresh damper oil and new seals for a full refresh.

Frequently Asked Questions

Which RockShox shocks does this damper shaft fit?

This assembly is made for the Deluxe Select+ (C1+) rear shock family from 2023 onward. Confirm fit by checking your shock model year and comparing the shaft service length to the available variants (37.5–45 mm, 47.5–55 mm, 57.5–65 mm).

How do I choose the correct length variant?

Measure the damaged shaft or consult your RockShox service manual to determine the correct service length range. If unsure, remove the damper internals and compare the exposed dimensions to the three available ranges to avoid ordering the wrong part.

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

A competent home mechanic with the right tools and RockShox service manual can install the assembly, but damper work requires specific tools, clean workspace and knowledge of torque and bleed procedures. If you’re not comfortable with damper teardown, have a certified suspension tech handle the job.

Do I need any other parts to complete a damper rebuild?

In most cases you’ll also need new seals, o-rings and damper fluid. We recommend replacing the damper seals and performing a full fluid change when replacing the shaft to ensure optimal performance and longevity.

Is this an OEM part and covered by warranty?

This is a genuine RockShox OEM part (Manufacturer Part #11.4118.111.451, Product #943243). Warranty coverage depends on RockShox’s policy and the circumstances of failure — keep purchase records and consult RockShox or your local dealer for warranty guidance.

What signs indicate I should replace the damper shaft?

Look for scoring or pitting on the shaft, inconsistent damping, leaking seals, or a floppy/lockout that doesn’t engage correctly. Any of these indicate internal wear and are good reasons to replace the shaft assembly to restore proper function.

Buying Guide

When buying a damper shaft assembly, prioritize OEM parts, exact service length and condition of surrounding internals. Measure the damaged shaft or consult the RockShox service manual to select the correct length variant; mismatched lengths can prevent proper reassembly or cause poor damping. Also plan to replace seals and damper fluid during the rebuild. Damper internals operate at tight tolerances — pairing the shaft assembly with a seal kit and fresh oil gives the best long-term performance and prevents repeated shop visits.
