HPOPUAUTO 2PACK Slack Adjuster Clevis Kit
Best for: Fleets needing a ready-to-install replacement set with a broad OEM compatibility footprint. This kit includes the clevis body and pins with a 5/8″-18 thread, designed to fit a wide range of air brake chamber applications. It is oriented toward heavy-duty trucks that require reliable, quick-change components to minimize downtime.
Why selected: The kit explicitly lists multiple replacements (R810019, E11430 variants) and commonly used part numbers, indicating broad interchangeability. It offers a center-to-center clevis pin spacing of 1.02 inches, which helps ensure a stable linkage between slack adjusters and chambers. Includes both the clevis and pins, simplifying on-truck service.
Limitation: Data notes multiple compatibility references; verify exact OEM fitment for your chassis to avoid mismatches with non-standard stroke lengths.
Mytee Products 4-Pack Clevis Pin Kit
Best for: Shops needing a compact, economical 4-pack solution compatible with standard-stroke brake chambers. Ideal for service fleets that perform frequent maintenance and replacements in a predictable, repeatable pattern.
Why selected: The Mytee option lists numerous OEM replacements (including Meritor, Automann, Euclid, Freightliner) and provides clear inclusion details (clevis body, pins, cotter pins), which aids quick inventory checks and fulfillment. The standardized thread 5/8″ x 18 enables straightforward cross-compatibility with many brake systems.
Limitation: The kit is sold in smaller quantities; consider purchasing larger packs if you service multiple vehicles to reduce recurring orders.
Mytee Products 8-Pack Clevis Pin Kit
Best for: Larger fleets or repair facilities that require a higher-volume, ready-to-ship clevis kit with redundancy and fast reorder capability. The 8-pack ensures ample spare parts for ongoing maintenance cycles.
Why selected: This pack also lists a broad range of OEM replacements and keeps the same 5/8″-18 thread standard, making it easy to stock and deploy across multiple trucks. It includes clevis bodies and pins along with cotter pins, streamlining on-truck replacements.
Limitation: Bulk packaging means higher upfront cost; ensure you have storage space for extra inventory.
Torque Type 30/30 Welded Clevis
Best for: Professionals seeking a long-stroke option with a welded clevis designed for heavy-duty, long-stroke applications. Suitable for trucks requiring a 3″ stroke with a robust weld to withstand harsh duty cycles.
Why selected: It covers a long-stroke 3030 configuration with precise dimensional data, including a 3″ stroke and an overall weight around 21.9 lbs. This makes it a dependable choice for installations that demand extended travel without sacrificing linkage integrity.
Limitation: Longer stroke may not suit standard 2.5″ stroke systems; confirm actuator compatibility before purchasing.
Torque Type 20 Long Stroke Clevis (2 Pack)
Best for: Fleets upgrading older long-stroke systems and service teams needing a heavy-duty weld-clevis pair for Type 30/30 and 20/30 configurations.
Why selected: Includes a robust set designed to replace multiple OEM parts (K067114, K129605, GC3030S4CW, and related models). It provides a 2.5″ stroke option and standard 3/8″-18 NPTF air port threads when applicable, enabling compatibility with many service brake chambers.
Limitation: The data focuses on compatibility notes; verify exact cylinder and clevis geometry to avoid misfit on nonstandard installations.
Buying Guide
What to check before buying clevis pins and bodies for brake chambers
- Thread size and pitch: Most products use 5/8″-18 threads. Verify both the thread diameter and pitch for your slack adjuster and chamber.
- Stroke length compatibility: Choose long-stroke or standard-stroke options based on your chamber model (2.5″ vs 3″ or more). Mismatched stroke can cause binding or incomplete return.
- OEM compatibility: Look for explicit replacement references (R810019, E11430, GC3030LCW, etc.) to confirm interchangeability with your existing system.
- Kit contents: Some listings include only the clevis body, while others provide pins and cotter pins. Choose kits that match your maintenance needs to avoid additional purchases.
- Diameter and pin center spacing: Confirm that the clevis pin center-to-center distance and pin diameter align with your slack adjuster and chamber mounting geometry (common values include a 1.02″ center-to-center spacing and 1/2″ to 5/8″ pins).
- Durability and welding: Welded clevis designs tend to be more robust in long-stroke or high-vibration environments. Consider the duty cycle of your application.
- Availability: If servicing a large fleet, consider multi-pack options to reduce reorder frequency and simplify inventory management.
Frequently Asked Questions
- Q: What is the standard clevis thread for most air brake systems?
A: The most common is 5/8″-18, but always confirm the exact specification for your brake chamber and slack adjuster. - Q: Should I choose a long-stroke clevis or a standard stroke?
A: Choose based on your chamber’s stroke specification. Long-stroke options are needed for 3″ chambers or specialized setups, while standard 2.5″ strokes suit many common systems. - Q: Do these kits include cotter pins?
A: Some listings include cotter pins and extra pins; check the product description to confirm included components and plan replacement parts accordingly. - Q: How can I ensure compatibility with my OEMs?
A: Look for explicit OEM cross-reference data in the features, and verify with your vehicle’s service manual or parts catalog before purchase. - Q: Is it better to buy a larger pack if I service multiple trucks?
A: Yes. Larger packs reduce reorder frequency and simplify stocking, but balance with warehouse space and budget. - Q: What spacing should I expect between clevis pins?
A: A common center-to-center distance is about 1.02 inches; verify against your existing hardware to ensure a proper fit.
