Titan 85569 4-Piece Slack Adjusting Tool and Wrench Kit | Heavy-Duty Truck Maintenance

The Titan 85569 4-Piece Slack Adjusting Tool and Wrench Kit is built for technicians and fleet crews who work on heavy-duty truck brake systems. This compact, durable set bundles precision tools designed to reach tight spaces and release tension without strain. Made in Taiwan, the kit blends reliable construction with practical design for everyday maintenance and on-the-road service.

What’s included

• Set contains three slack adjusting wrenches: 5/16-Inch, XL 7/16-Inch, and XL 9/16-Inch, plus a Slack Adjusting Tool

Use the XL 7/16-Inch wrench to speed up installation on Haldex heavy-duty truck brake slack adjusters, the XL 9/16-Inch wrench for Bendix systems, and the 5/16-Inch wrench for Meritor units. The assortment covers common configurations, reducing the need to switch tools mid-task and helping you maintain momentum through each job.

Designed for reach and versatility

• XL wrenches enable access to recessed adjusters and the 5/16-Inch wrench has an angled head to provide additional clearance for hands
• XL wrenches feature a built-in ratcheting mechanism with a full 360-degree swing, allowing continuous motion in tight spaces
• The fork-end release tool securely holds the tensioner release button without prying or damaging surrounding components

Real-world benefits and use cases

In the shop or on the road, this kit supports smoother brake slack adjustments. The 360-degree ratchet reduces awkward hand positions, while the angled 5/16 head helps you work in cramped areas. The dedicated release tool adds a safer, controlled option for tensioner activation, which can help minimize the risk of damage during maintenance.

Durability and origin

Designed for regular, demanding use, the tools are built to withstand repeated adjustments on heavy-duty trucks. The Titan kit is manufactured in Taiwan, reflecting a commitment to precision machining and reliable fit and finish that professionals rely on.

How to use and care

• Start with the 5/16 for Meritor units and verify access before applying force
• When facing recessed adjusters, switch to XL wrenches for more reach and rotation
• Use the 360-degree ratchet for continuous motion and reduced torque on sensitive components

Care and storage: wipe tools after use, keep them dry, and store in a cool, dry place to maintain finish and prevent corrosion.
