Dexter T1242600 Replacement Shock for Model 6 and Model 10 Brake Actuators

Replacement shock for Dexter Model 6 and Model 10 brake actuators. Designed to restore proper actuator damping in compatible hydraulic drum brake and disc brake surge actuator applications.

Part Number: T1242600 Fits Dexter Model 6 & Model 10 Includes 1 Shock

Overview

This Dexter T1242600 replacement shock is used on compatible Dexter Model 6 and Model 10 brake actuators. The actuator shock helps control surge coupler movement during compression and rebound, supporting smoother brake engagement and proper actuator function when the trailer pushes forward during braking.

R&P Service Insight

A weak, worn, or leaking actuator shock can make a surge brake coupler feel harsh, loose, or inconsistent. Replacing the shock is a practical service step when rebuilding or repairing a compatible Dexter Model 6 or Model 10 actuator.

  • Coupler Control: Helps dampen actuator movement during brake apply and release.
  • Brake Feel: A worn shock can contribute to clunking, grabbing, or uneven actuator motion.
  • Service Check: Verify actuator model, shock length, mounting ring sizes, and required quantity before ordering.

R&P Knowledge Hub

Compatibility: Replacement shock for Dexter Model 6 and Model 10 brake actuators.

Vehicle / System Fit: Used in compatible surge brake actuator assemblies for hydraulic drum brake and disc brake trailer systems.

Installation Notes: Confirm the actuator model and compare the removed shock to the listed extended length, collapsed length, mounting ring inner diameters, and body diameter before installation.

Performance Insight: The actuator shock controls compression and rebound inside the surge coupler, helping reduce harsh movement and supporting consistent brake actuator operation.

Brand & Fitment Note

Selling Brand: Dexter

Application Reference: Dexter Model 6 and Model 10 names in this listing describe supported brake actuator compatibility for this replacement shock.

What This Means: This listing is for one Dexter T1242600 replacement actuator shock for listed compatible brake actuator applications.

Before Ordering: Verify actuator model, mounting points, extended and collapsed length, mounting ring inner diameters, body diameter, and required shock quantity before installation.

R&P Repair Insight

Actuator shocks are small internal service parts, but they play an important role in surge brake control. Before replacing the shock, inspect the actuator for worn pins, damaged mounting hardware, corrosion, bent components, or other issues that could affect proper coupler movement.

  • Model Check: Confirm you are servicing a Dexter Model 6 or Model 10 brake actuator.
  • Quantity Check: This listing includes 1 shock; some Model 10 actuator assemblies may require 2 shocks.
  • Measurement Check: Compare your existing shock to the listed 8-1/16" extended length, 6" collapsed length, and mounting ring inner diameters before installation.
