Description
Product Overview
The Buyers Products Lift Axle Control Assembly with toggle air valve is engineered to give commercial vehicle operators precise, in‑cab control over air suspension and lift‑axle functions. Constructed from high‑strength nylon components and a powder‑coated steel mounting plate, the assembly resists corrosion, wear, and the harsh environments typical of heavy‑duty trucking. The unit arrives fully pre‑plumbed and assembled, eliminating the need for field wiring or complex pipework. With a 0.25‑inch NPT inlet and outlet, the assembly integrates seamlessly with standard DOT‑rated tubing, providing a leak‑free connection that meets industry safety standards. The compact 7.63 × 7 × 8‑inch footprint and 2.43‑pound weight make it easy to install in confined cab spaces while maintaining robust performance under load.
Usage
This control assembly is ideal for medium‑ and heavy‑duty trucks, trailers, and vocational vehicles that rely on air‑suspended lift axles. It is commonly used in long‑haul rigs, delivery trucks, and construction equipment where drivers need to raise or lower the rear axle to adapt to varying load conditions. The toggle valve design allows quick, binary operation—simply pull the lever to engage lift, release to lower—making it intuitive for drivers who may be operating the vehicle for extended periods. The pre‑plumbed configuration reduces installation time, allowing service technicians to focus on mounting the steel plate and connecting the 0.25″ NPT fittings without worrying about leaks or misaligned tubing. The assembly’s durability ensures reliable performance in extreme temperatures, from icy winter roads to hot desert climates.
Why Choose Us
Buyers Products has a reputation for delivering industrial‑grade components that meet rigorous quality standards. Each Lift Axle Control Assembly undergoes a multi‑stage testing process, including pressure testing, corrosion resistance evaluation, and functional verification of the toggle mechanism. The inclusion of a corrosion‑resistant powder‑coated steel mounting plate adds an extra layer of protection against road‑salt and moisture, extending the service life of the product. Our pre‑plumbed design not only speeds up installation but also reduces the risk of installation errors that can lead to costly downtime. Additionally, Buyers Products offers responsive technical support and a comprehensive warranty, giving fleet managers confidence that any issues will be addressed promptly.

FAQ
What size tubing does this assembly require?
The unit uses 0.25‑inch NPT inlet and outlet connections, which are compatible with standard DOT‑rated air suspension tubing commonly used in commercial trucks and trailers.
Is the mounting plate included, and what material is it made from?
Yes, a powder‑coated steel mounting plate is included. The coating provides corrosion resistance, while the steel base offers the strength needed to securely anchor the assembly to the vehicle chassis.
Can this assembly be retrofitted onto an existing air suspension system?
Absolutely. Because the assembly is pre‑plumbed and uses standard NPT fittings, it can be added to an existing air suspension setup with minimal modifications. A qualified technician can mount the plate, connect the tubing, and the system will be ready for operation.
What is the expected lifespan of the nylon components?
The high‑grade nylon used in the valve body is designed to withstand repeated cycling, temperature extremes, and exposure to moisture. When installed correctly and maintained according to manufacturer guidelines, the components typically last the lifetime of the vehicle’s air suspension system.
Do you provide installation assistance or documentation?
Buyers Products supplies detailed installation instructions with every unit, and our technical support team is available to answer any questions during the installation process. We also offer optional on‑site assistance for larger fleet deployments.
