5 Best Air Locker Manifold Kits Compareds for Trail Builds (2026)

Updated November 2026

Choosing an air locker manifold kit comes down to three things: whether it matches your compressor and locker setup, how many circuits it needs to feed, and whether the fittings and hose routing will fit inside a crowded engine bay. This list compares five manifold-based kits sold on Amazon US. Each one is judged on its listed port count, its intended pairing with compressors and lockers, and the patterns owners tend to report about installation and day-to-day use. We did not bench-test these products. Everything below comes from manufacturer specifications, brand reputation and common owner feedback.

ARB 4X4 Accessories High Performance Twin Air Compressor 12 Volt Bundle with Air Locker Manifold Kit

Best for: Twin-compressor builds

Builders who want two compressors feeding a locker manifold from a single kit, rather than sourcing each piece separately, will find this bundle the most direct route.

Key specs

• High performance twin air compressor, 12 volt
• Includes air locker manifold kit

Pros

• Twin compressor setup supports faster tank refill
• Bundled manifold reduces mismatched components
• Consistent with ARB’s air locker design approach

12V Air Ride Suspension Manifold Kit with 8 Air Ride Solenoid Valves

Best for: Multi-circuit air systems

This kit fits owners running several independent air circuits, such as lockers plus suspension, who need individual valve control at each outlet.

Key specs

• 12 volt operation
• Eight air ride solenoid valves

Pros

• Eight valves allow separate control of multiple circuits
• Useful for combined locker and suspension air systems
• Single manifold keeps the air plumbing organized

Cons

EZ FLATE Air Command Auto Air Inflation/Deflation Manifold (Air Command Manifold with Recoil Hose Kit)

Best for: Inflation-focused setups

Owners who spend most of their air budget on tire inflation and deflation, and want a manifold that handles both directions with a recoil hose, will find this the most relevant option.

Key specs

• Auto air inflation and deflation manifold
• Includes recoil hose kit

Pros

• Handles both inflation and deflation from one manifold
• Recoil hose keeps the line tidy in the engine bay or rear quarter
• Useful for trail tire pressure changes

Cons

• Less focused on dedicated locker circuits
• May need an additional locker-specific setup for a full air locker system

Bottom line: A good fit for owners whose main goal is tire pressure management, with lockers as a secondary consideration.

Viair 80201 200PSI Dual OBA Hook Up Kit with Manifold 0.25-0.125 Ports

Best for: Budget builds and simple two-port setups

This is a simpler dual-outlet manifold for builders who need two connections and a 200 PSI rating without a large multi-valve system.

Key specs

• 200 PSI rating
• Dual outlet manifold
• 0.25 and 0.125 port sizes

Pros

• Simple dual-port layout is easy to plan
• Mixed port sizes suit different fittings
• Budget-friendly way to add a manifold

Cons

• Only two outlets limits expansion
• Owners often report needing extra fittings to match some layouts

Bottom line: A practical choice for a two-circuit build where cost and simplicity matter more than expansion room.

Buying Guide

Number of circuits and ports

Count your lockers and any other air users before buying. A front and rear locker needs at least two outlets, and adding suspension or a tire inflation line means more. Leave one spare port if you expect to grow the system later.

Compressor compatibility

Match the manifold to your compressor’s output and pressure rating. A single compressor may run a short locker cycle comfortably, while a twin setup helps when you are refilling tanks or running multiple circuits. Check that the manifold’s rated pressure is at least as high as your compressor’s maximum.

Ecosystem and locker brand

Some manifolds are designed around a specific locker brand’s air circuit. Mixing brands can work, but it usually means adapter fittings and more troubleshooting. Confirm your locker’s port size and required pressure before you buy.

Port sizes and fittings

Check the port threads and hose sizes. Mismatched 1/4 and 1/8 inch fittings are a common source of leaks. Keep a few adapters on hand, and use thread sealant rated for compressed air where the manufacturer recommends it.

Pressure rating and duty cycle

Confirm the manifold’s maximum pressure rating is above the compressor’s cutoff pressure with some margin. Consider how often you will run the system; frequent cycling generates heat, so mount the compressor where it gets airflow.

Mounting space and routing

Measure the mounting area before ordering. Manifolds need room for valves, hoses and a clear path to the axle lines. Recoil hoses and bulkhead-mounted manifolds reduce clutter, but still need protection from heat and rock strikes.

Wiring and electrical load

Solenoid-heavy kits draw more current and need proper fusing and relay wiring. Plan a dedicated circuit from the battery and check the wire gauge against the total amperage. If you are unsure about wiring a high-current circuit, consult a qualified auto electrician.

FAQ

What is an air locker manifold kit?

It is a set of valves, fittings and hoses that distributes compressed air from a compressor to one or more air lockers. The manifold lets you control each locker separately and manage pressure from a single point in the system.

Do I need a manifold if I only have one air locker?

Not always. A single locker can be plumbed directly from the compressor with a valve and a few fittings. A manifold becomes useful when you add a second circuit, want cleaner routing or plan to run tire inflation from the same system.

Can I use a manifold from a different brand than my locker?

It is possible, but you will often need adapter fittings to match port sizes and thread types. Confirm the locker’s required pressure and port size before buying, and test for leaks after installation.

What pressure rating should I look for?

Choose a manifold rated above your compressor’s cutoff pressure. Many trail systems operate in a range that a 200 PSI-rated manifold can handle, but always confirm the specific pressure requirements in your locker and compressor documentation.

How do I know if my manifold is leaking?

Pressurize the system, shut off the compressor, and check for pressure drop over several minutes. Apply soapy water to fittings and look for bubbles. Tighten or reseal any leaking connections.

Does a twin compressor setup matter for lockers?

A twin setup can refill the air tank faster and handle multiple circuits more comfortably. For a single locker used occasionally, one compressor is often enough. Consider your typical usage before adding a second unit.

Is professional installation recommended?

Many owners install these kits themselves, but high-current wiring and any work on axle or differential components benefit from a qualified installer. If you are unsure, consult a professional mechanic or auto electrician.

Conclusion

For a locker-focused trail build that already uses or plans to use ARB equipment, the ARB 171503 CKMTA12 ARB505 Air Compressor Manifold kit offers the most coordinated path. Builders who need two compressors should look at the ARB 4X4 twin compressor bundle. Multi-circuit systems that also run suspension fit the 12V Air Ride manifold with eight valves. The EZ FLATE manifold suits tire-pressure-first builds, and the Viair dual-port kit works for simple two-circuit setups on a tighter budget. Match the manifold to your circuit count, compressor and locker brand, and check pressure ratings before you buy.
