HUTUDAN Adjustable Height Control Linkage Rods 2-Pack 13.5-19.5in — Heavy-Duty, Trim-to-Fit

HUTUDAN's 2-pack adjustable linkage rod kit replaces common OEM height control valve linkages, offering 13.5–19.5" adjustability for semi-truck and heavy-duty air suspensions.

When a height control valve linkage wears, bends, or becomes the source of unpredictable ride height, a quick, reliable replacement restores proper suspension operation. This HUTUDAN kit supplies two adjustable rods plus hardware engineered to match many OEM part numbers such as Haldex 48100225, Neway SRK168, and Meritor R307852. The rods are built for heavy use and give technicians flexibility during installation by trimming or adjusting length to fit multiple vehicle configurations.

How does this kit adapt to different truck models and suspension layouts?

The rods adjust from 13.5" to 19.5" and include an 18" straight rod that can be trimmed to a precise length during installation. That flexibility covers a wide range of heavy-duty commercial vehicles and lets you fine-tune linkage geometry for accurate height control.

• Adjustable length: 13.5"–19.5" range for varied fitment
• Trim-to-fit 18" rod for custom installations
• Designed to replace many OEM numbers for cross-compatibility

What hardware comes in the box and is it ready for immediate installation?

Each pack includes the main adjustable rod plus mounting pieces and small parts required for installation, so technicians won’t have to source extras. The kit contains rubber end caps and hose clamps to secure connections and protect pivots, simplifying a typical repair job.

• 1x 18" adjustable rod per pack
• 2x rubber end caps to reduce vibration and wear
• 2x hose clamps and mounting fasteners included

Will this linkage kit withstand heavy-duty use and harsh conditions?

These rods are manufactured from durable materials intended to hold up under frequent cycles and the stresses of commercial operation. The design focuses on maintaining precise valve actuation and resisting premature wear, helping stabilize ride height and suspension response when fitted correctly.

• Heavy-duty construction for long service life
• Protective caps minimize metal-on-metal wear
• Engineered to restore reliable height control and dump valve response

How do I confirm compatibility with my truck before buying?

Check your vehicle's current OEM linkage part number against the cross-reference list and verify mounting geometry and valve type. If your truck uses Haldex 48100225, Neway SRK168, Meritor R307852, Navistar 1675187C91, or a listed equivalent, this kit is a likely match; when in doubt, compare dimensions and thread sizes.

• Compare the OEM part number to cross-reference list in the product details
• Measure existing linkage length and thread pitch before installation
• Contact support with vehicle make/model and current part number for verification

Who this is for: fleet maintenance managers, independent diesel technicians, and owner-operators who need a reliable, adjustable replacement for worn height control linkages. The two-rod pack is ideal for servicing multiple axles or keeping a ready spare on hand. Choose this kit if you want cross-compatible parts built for commercial workloads and the flexibility to trim and tune linkage length during repair.
