RockShox Shock Bushings 3-Piece 1/2" – 8x20.0, Standard, Black

Keep Your Suspension Running Smooth – RockShox Shock Bushings 3-Piece Set

Every time you drop into a technical descent or absorb a hard landing, your rear shock bushings are working hard. Over time, they wear down — and when they do, you’ll feel it: play in the linkage, creaking under load, and a suspension that no longer tracks the trail with precision. The solution is simple: replace them with genuine RockShox Shock Bushings.

This 3-piece standard set includes two flanged outer cups and one inner sleeve, all precision-machined to RockShox tolerances. Designed for 1/2" (12.7 mm) hardware with an 8x20.0 mm configuration, these bushings restore the tight, rattle-free feel your suspension had when it was new.

Frequently Asked Questions (FAQ)

What is included in this 3-piece bushing set?

The set includes two flanged outer cups (the wider-rimmed pieces that seat into the shock eye or frame mount) and one inner sleeve (the cylindrical piece that the bolt passes through). Together, these three pieces make up a complete bushing assembly for one mounting point on your rear shock.

How do I know when my shock bushings need replacing?

Common signs of worn shock bushings include: lateral play or wobble at the shock mount, creaking or knocking sounds when riding over bumps, visible wear or deformation on the bushing surfaces, and a generally vague or imprecise suspension feel. If you notice any of these, it’s time to replace the bushings.

Is this set compatible with my RockShox shock?

This set is designed for RockShox rear shocks using 1/2" (12.7 mm) hardware with an 8x20.0 mm bushing configuration. Always verify your shock’s bushing size before ordering — you can find this in your shock’s manual or on the RockShox website using your shock’s model and year. Common compatible shocks include many versions of the Monarch, Deluxe, Super Deluxe, and Vivid series, but always confirm your specific model.

Can I install these bushings myself, or do I need a bike shop?

Bushing replacement requires a bushing press tool (or a suitable substitute) to press the cups in and out without damaging the shock eye or frame. Experienced home mechanics with the right tools can do this job, but if you’re unsure, we recommend having a qualified bike mechanic perform the installation to avoid damage to your frame or shock.

Do I need to replace bushings on both ends of the shock at the same time?

It’s good practice to inspect both the shock eye (lower mount) and the frame mount (upper mount) when servicing. If one set is worn, the other is likely not far behind. Replacing both at the same time saves labor and ensures consistent suspension performance. You’ll need one 3-piece set per mounting point.

What tools do I need to replace shock bushings?

You will need: a bushing press or bearing press tool (RockShox sells a dedicated tool, or a generic press with the correct adapters works), a torque wrench for reinstalling the shock bolt to spec, and basic hex keys. Some mechanics use a vice with appropriate sockets as a DIY press — this works but requires care to avoid damaging the bushing or shock eye.

How often should shock bushings be replaced?

There is no fixed interval — it depends on riding style, conditions, and how well the shock is maintained. As a general guideline, inspect your bushings every 50–100 hours of riding or at least once per season. Riders who frequently ride in wet or muddy conditions should inspect more often, as contamination accelerates wear.

Are these bushings compatible with non-RockShox shocks?

These are genuine RockShox parts designed specifically for RockShox shocks. While the physical dimensions (8x20.0 mm, 1/2") may match some other brands’ shocks, we recommend using manufacturer-specified parts for non-RockShox components to ensure proper fit and warranty compliance.
