Product Details

Overview & Technology

RockShox 1/2" Rear Shock Bushing Tool (Product #900190, MPN 00.4315.026.010) is a purpose-built driver for installing and removing rear shock eyelet and sealhead bushings with precision. Designed around the SRAM model ID TL-RST-BUSH-A2, this 1/2" driver gives technicians predictable seating and alignment when servicing RockShox shocks. The tool is machined for tight tolerances and finished with a corrosion-resistant surface to withstand shop use. Using a correctly sized, hardened driver prevents damage to shock eyelets and ensures bushings are pressed in square — translating to smoother suspension movement and longer bushing life.

Key Features

Durable construction: The driver is built from heat-treated, precision-machined steel with a wear-resistant finish for long service life and consistent performance under press loads. • Exact 1/2" diameter: Matches RockShox eyelet & sealhead specifications for accurate installs. • SRAM model ID: TL-RST-BUSH-A2 compatibility means it fits standard RockShox service procedures. • Shop-ready size: Compact shipping weight (0.1 lb) and small footprint make it ideal for service benches and mobile tech kits.

Fit & Compatibility

This tool is specifically sized for 1/2" rear shock eyelet and sealhead bushings found on many RockShox models. Confirm fit by checking your shock's bushing inner/outer diameters against RockShox service documentation or the SRAM TL-RST-BUSH-A2 reference. While optimized for RockShox, the driver will often work with other brands that use the same 1/2" bushing dimension — always verify dimensions before use. It integrates with standard hydraulic or arbor presses and is intended for use by technicians familiar with suspension servicing.

Who It's For

This tool is made for bike mechanics, independent suspension techs, and advanced home mechanics who perform rear shock service. If you rebuild or replace shock bushings regularly, a dedicated RockShox driver saves time and prevents damage caused by improvised tools. Casual riders who rarely open shocks can still benefit by owning this tool if they prefer to do their own suspension maintenance, but most riders will find it best purchased by shops or serious DIYers who already use a press and understand torque and alignment requirements.

Frequently Asked Questions

Which shocks is this tool compatible with?

This 1/2" driver is designed for RockShox rear shock eyelet and sealhead bushings that use a 1/2" dimension and is referenced by SRAM model ID TL-RST-BUSH-A2. Check your shock's service manual or bushing spec to confirm compatibility before use.

Can I use this tool with a bench or hydraulic press?

Yes. The tool is intended for use with standard arbor or hydraulic presses. Apply steady, controlled force and follow the shock manufacturer's removal/installation procedure to avoid misalignment or damage.

Is this safe for at-home mechanics?

Yes, but only if you have the correct press and basic suspension servicing experience. Improper pressing can damage shocks; if you're uncertain, have a trained technician perform the work.

What material is the driver made from?

The driver is precision-machined from heat-treated steel with a corrosion-resistant finish to withstand repeated press cycles and provide consistent mating with bushings.

Will this tool work for other brands?

It may work for other manufacturers that use the same 1/2" bushing dimensions, but compatibility isn't guaranteed. Always measure bushing dimensions or consult the shock maker's specs before using.

Does it include any adapters or accessories?

This listing is for the single 1/2" driver tool (RockShox Rear Shock Bushing Tool). Adapters, presses, or additional drivers are sold separately.

Buying Guide

When choosing a rear shock bushing tool, prioritize exact sizing and build quality. A driver that matches the shock manufacturer's specification (here, 1/2" and SRAM TL-RST-BUSH-A2) gives reliable, square seating — critical to prevent premature wear and bind in suspension bearings. Also consider how often you'll use the tool. Heat-treated, precision-machined drivers are worth the investment for shops and regular DIY mechanics; occasional users may opt to have a shop perform the service to avoid buying press equipment and specialized drivers.
