THE SELECTED CONFIGURATION

Specifications & fitment

Manufacturer / component part
20053
Selected configuration
85 PSI ON / 105 PSI OFF
Vehicle fitment evidence
Universal custom air-system controls, not a vehicle-specific bolt-on LC250 kit. Conditional for US-market 2024+ Land Cruiser 1958 / Land Cruiser / 2024 First Edition after installer confirmation of low-voltage circuit, routing and system compatibility. No connection to the hybrid high-voltage system.
Package contents
One illuminated dash gauge with on/off switch, one pressure switch with built-in relay, 20 ft air line, fused positive lead, listed NPT/compression/quick-connect fittings, terminals and mounting hardware. No compressor, tank or LC250 mounting bracket.

Weight basis
Complete assembly gross mass and net installed vehicle addition are unverified. Commerce/shipping weights are not used as installed mass. Include fasteners, added equipment and any removed factory parts when calculating loads.
Professional installation
1–2 hr · researched planning estimate
Installation scope
Researched professional allowance using Quadratec’s published 1–2 hour SKU 20053 installation expectation and VIAIR’s gauge, airline, pressure switch, wiring and leak-check procedure. 20055 shares this procedure. Manufacturer hours are not published.
Fitment / supporting work
This kit switches a compatible compressor to maintain tank pressure. It does not supply compressed air by itself, and tank switch settings are not the desired tire-inflation pressure.

Why consider this?

Select controls only after choosing a compatible compressor and tank. Plan mounting, protected wiring, air routing and safety hardware together to avoid duplicate parts and repeat labor.

Required equipment & checks

Planning requirements for this product. Your exact vehicle and complete build still need confirmation.

included

Selected product / listed contents

One illuminated dash gauge with on/off switch, one pressure switch with built-in relay, 20 ft air line, fused positive lead, listed NPT/compression/quick-connect fittings, terminals and mounting hardware. No compressor, tank or LC250 mounting bracket.

check

Compatible compressor

Confirm compressor current does not exceed the manual’s 30A limit, and compressor/tank/lines/gauge/safety devices tolerate the 105 PSI cut-out. Complete air systems may already include controls; do not buy duplicate hardware.

Explore supporting equipment →
check

Separate compatible air tank

A separately mounted, rated air tank is required; none is included. Verify matching ports, pressure relief, check valve, drain and supported mounting. No catalog compressor selection proves that a tank is supplied.

Explore supporting equipment →
check

Match pressure, current and safety hardware

Choose 85/105 PSI for the complete system, not tire pressure. Verify pressure relief, check valve and drain provisions with compressor/tank instructions, circuit protection, conductor size, relay and voltage compatibility. A supplied larger fuse does not raise the 30A compressor limit.

Explore supporting equipment →
check

Protected air-line and electrical routing

Manual calls for drilled gauge mounting holes and potentially a protected firewall pass-through. Keep airline clear of heat and abrasion; verify occupied cabin, airbags and wiper/visibility clearances. Quote compressor/tank mounting separately.

Installation / compatibility notes

This kit switches a compatible compressor to maintain tank pressure. It does not supply compressed air by itself, and tank switch settings are not the desired tire-inflation pressure.

Installed net weight

Product weight or factory equipment removed is not fully verified. Do not use shipping weight or assume zero additional load.

Questions before buying

Is VIAIR Onboard Air Hookup Kit verified for every LC250?

Universal custom air-system controls, not a vehicle-specific bolt-on LC250 kit. Conditional for US-market 2024+ Land Cruiser 1958 / Land Cruiser / 2024 First Edition after installer confirmation of low-voltage circuit, routing and system compatibility. No connection to the hybrid high-voltage system. A catalog listing is not approval of your entire modified vehicle.

What does the price include?

One illuminated dash gauge with on/off switch, one pressure switch with built-in relay, 20 ft air line, fused positive lead, listed NPT/compression/quick-connect fittings, terminals and mounting hardware. No compressor, tank or LC250 mounting bracket. The listed $146.75 covers selected configuration. Unpriced mounts, wiring, services, tax and shipping remain additional.

Is the installation time manufacturer-published?

This entry uses a researched professional planning estimate. Researched professional allowance using Quadratec’s published 1–2 hour SKU 20053 installation expectation and VIAIR’s gauge, airline, pressure switch, wiring and leak-check procedure. 20055 shares this procedure.
