Overview & Technology

RockShox Rear Shock Vise Blocks (3-Hole) are purpose-built fixtures that let you clamp rear shocks securely in a bench vise for safe, accurate maintenance and rebuilds. Designed around RockShox's mounting pattern, these blocks match factory eyelet spacing for Monarch, Vivid, Vivid Air and Reverb models so the shock sits true and undistorted while you work. The blocks are precision-shaped to distribute clamping forces evenly and include protective contact faces to prevent marring anodized or painted shock bodies. Listed manufacturer references: Product #901538, MPN 00.4115.154.020, SRAM Model ID TL-RST-VB-A1. Shipping size is compact (5" x 4" x 1.3") and weight is light (0.45 lb), making them easy to keep in a home workshop or pro service bench.

Key Features & Construction

Durable, service-ready construction: The blocks are CNC-contoured for a precise fit against RockShox eyelets and feature a hard-anodized aluminum body that resists corrosion and wear. Shock-facing surfaces use a tough polymer pad to protect finishes and increase grip without excessive compression. Real-world benefits: The rigid aluminum core prevents compression or bending under vise pressure, while the polymer pads stop scratches and evenly distribute clamp force — critical when torquing shaft hardware or performing seal replacement. The 3-hole pattern aligns with common service fixtures for fast setup.

Fit, Compatibility & Use

These vise blocks use a three-hole mounting pattern that matches RockShox rear shocks including Monarch, Vivid, Vivid Air and some Reverb variants. They locate on the shock eyelet so the clamp grasps the body rather than the shaft, keeping suspension internals safe while you disassemble components. For best results, pair the blocks with a bench vise that has flat jaws and enough opening to accommodate the assembled block and shock. Always check that the shock is supported at the eyelet and that polymer contact faces are clean to avoid marring. If your shock uses non-standard hardware or spacing, confirm fit before applying full clamping force.

Who This Tool Is For

This is an essential accessory for mountain bike mechanics, home wrenchers and shops that service RockShox shocks. If you rebuild seals, replace bushings, or perform routine shaft-and-air-spring maintenance on Monarch/Vivid/Reverb shocks, these vise blocks make the job safer, faster and repeatable. They’re also ideal for suspension techs who value tidy, damage-free service — the blocks reduce risk of cosmetic damage and help keep shocks perfectly aligned during sensitive operations like air can removal and damper disassembly.

Frequently Asked Questions

Which RockShox models fit these vise blocks?

The 3-hole Rear Shock Vise Blocks are designed for RockShox rear shocks such as Monarch, Vivid and Vivid Air, and many Reverb variants. Always check your shock's eyelet spacing against RockShox documentation to confirm compatibility.

Can I clamp the shock by the shaft with these blocks?

No. These blocks are made to support and clamp at the eyelet or shock body so the shaft and seals are not stressed. Clamping the shaft can damage seals and internal components; use the blocks to protect the shock during service.

What material are the blocks made from and why does it matter?

The blocks feature a precision aluminum core with protective polymer contact faces. Aluminum gives rigid, non-deforming support under vise pressure while the polymer pads prevent cosmetic damage and improve grip — together they provide safe, repeatable clamping.

Will these blocks fit in any bench vise?

They fit most bench vises with a flat jaw surface and sufficient opening width for the assembled block and shock. For best stability, use a vise with long, parallel jaws and avoid heavily serrated jaws that can press through protective pads.

How should I maintain the vise blocks?

Wipe off grease and dirt after each use and inspect the polymer contact faces for wear. Replace the pads if they become torn or excessively compressed. Store the blocks dry to preserve the anodized finish and polymer longevity.

Is this an official RockShox part and what are the identifiers?

Yes — this is a factory RockShox vise block assembly. Manufacturer references include Product #901538, MPN 00.4115.154.020 and SRAM Model ID TL-RST-VB-A1.

Buying Guide

When buying rear shock vise blocks, prioritize fit and protective contact surfaces. Look for blocks that match your shock's eyelet pattern (3-hole vs 2-hole) and use protective polymer or rubber faces to avoid damaging anodized finishes during clamping. A rigid metal core (often CNC-machined aluminum) gives stable support without deformation. Also consider shop workflow: compact, lightweight blocks are convenient for mobile techs, while replaceable contact pads extend service life. Pair the blocks with a wide, flat-jawed bench vise and the correct RockShox service kits for reliable, repeatable shock maintenance.
