ARB Dana 60 Air Locker Review (2026): Features and Performance
Reviewing the ARB Dana 60 air locker: specs, pros and cons, performance notes and who should buy it, plus alternatives for your Dana 60 axle build.
The ARB Dana 60 air locker is a front or rear locking differential built for the Dana 60 axle, a heavy-duty housing found under many full-size trucks and Jeep Wranglers that run Dana axles. It replaces the open or limited-slip carrier with a locker that engages on command using compressed air, so both wheels on the axle turn together. This review is research-based: it draws on manufacturer specifications and patterns that owners commonly report, not on hands-on testing. The ARB Dana 60 air locker suits off-roaders who want selectable traction, already run an air compressor or are willing to add one, and accept a locker that is slower to engage than a fully automatic unit. It is a weaker choice for daily drivers who rarely leave pavement, for owners who want a locker that engages with no driver input, and for anyone whose axle is not actually a Dana 60.
Product Overview
ARB is an Australian company known for bumpers, recovery equipment and differential lockers. Its air-actuated lockers use a piston that is pushed by compressed air through a solenoid valve in the cab, and the locking mechanism sits inside the carrier. Because the locker is air-operated, it does not need an electric motor or cable pull, which is one reason it is popular with owners who want a clean, reliable engagement method.
The Dana 60 variant is designed to fit the common Dana 60 housing and its ring gear, and ARB offers kits that include the locker body, the air solenoid, the hose set and mounting hardware. Installation generally requires removing the differential carrier, so most owners either have a shop do the work or pull the cover themselves with the right tools and a service manual in hand.
Owners often describe the locker as a set-and-forget upgrade once it is plumbed correctly. The main ongoing requirement is a source of compressed air, which is usually a dedicated 12-volt compressor mounted in the engine bay or under the bed, along with a tank or regulator to keep pressure steady.
Key Features & Specifications
| Feature | Details |
|---|---|
| Fitment | Dana 60 front or rear axle (verify ring gear and carrier model before ordering) |
| Actuation | Air-operated, driver-controlled from the cab |
| Locking type | Full-locking differential (both wheels rotate at the same speed when engaged) |
| Air supply | Requires a compressor and air hose system; regulated pressure is recommended by manufacturers |
| Control | Dash-mounted switch with solenoid valve and indicator light, typically included in the kit |
| Installation | Requires differential carrier removal, gear setup and ring-and-pinion compatibility check |
| Intended use | Off-road and trail use, with the driver managing when the locker is engaged |
Exact pressure ratings, weight and part numbers vary by kit and by the model year of the housing, so check the manufacturer’s installation sheet before purchase. Manufacturers generally recommend that the air system be sized to the locker’s cycle requirements, and some kits call for a dedicated air tank for quicker engagement.
Pros & Cons
Pros
- Driver-selectable engagement lets you run open on pavement for normal steering and tire wear, then lock on trail.
- Air actuation avoids cable or electric motor wear points and is straightforward to diagnose with a pressure gauge.
- Full locking gives true 100% power to both wheels when engaged, which helps on steep climbs and uneven ground.
- Fits the widely used Dana 60 platform, so parts and service knowledge are easy to find.
- Owners frequently mention that it is quiet and reliable once the air system is set up correctly.
Cons
- Requires a compressor, hoses, solenoid and wiring, so the total build is more involved than a simple switch-and-go locker.
- Installation is labor-intensive and usually requires pulling the carrier, which makes professional installation a sensible choice for many owners.
- Full-locking differentials can cause tire scrub and binding on pavement if left engaged, so drivers must disengage before road use.
- Engagement is not instant; air must build pressure, and cold weather or a leaky line can slow things down.
- Not suitable for owners who want a fully automatic locker that engages without any driver input.
Performance Analysis
Performance comes down to three things: how well the locker engages, how it handles the stress of loaded torque, and how it behaves on road. On engagement, owners commonly report that the locker locks reliably once air pressure reaches the manufacturer’s recommended range. Engagement time depends on the compressor’s output, hose length and whether a tank is used. A short, well-sized air line tends to produce a faster and more consistent lock than a long run with multiple fittings.
Under load, a full locker removes the differential action entirely. That is ideal for climbing and for keeping momentum on uneven terrain, but it also places more stress on axle shafts, gears and the carrier. Owners often recommend pairing the locker with appropriately rated axle shafts and a careful approach to hard throttle inputs. Heavier tires and high-torque engines raise the stakes, so the Dana 60 housing, gear ratio and shaft strength should be matched to the rig’s use.
On pavement, a locked axle scrubs tires and can make the vehicle hop or bind in tight turns. For that reason, most drivers treat the air switch as a trail-only tool and return the locker to open before highway speeds. Owners generally note that the discipline of switching the locker on and off becomes second nature after a few outings. Gear noise is minimal in normal use, though some owners mention a faint chatter during tight turns when the locker is engaged, which is expected behavior for a full locker.
Who Should Buy This Product?
This locker makes sense for owners of Dana 60-equipped trucks and Jeeps who spend meaningful time on trails, rock crawls, sand or snow, and who want the traction of a locked axle without giving up daily drivability. It also suits builders who already have or plan to install an onboard air system for tires or other accessories, since the compressor can serve double duty.
You should skip it if you rarely leave pavement, if you want a locker that engages automatically with no switch, or if your axle is a different housing such as a Dana 44 or 35. Owners on tight budgets may also find that the total cost of compressor, hoses and installation outweighs the benefit for light trail use, where a selectable traction system or a limited-slip could be enough.
Buying Guide
Before buying, confirm the axle type. Look for the Dana 60 stamp on the housing, count the ring gear bolts and verify the gear ratio you run. Check whether you need a front or rear locker, and whether your carrier is the right style for the kit. If you are unsure, bring the old carrier or the axle codes to the seller.
Plan the air system early. A typical setup includes a 12-volt compressor, a regulator or tank, air-rated hose, a solenoid valve, a dash switch and a pressure gauge for diagnosis. Keep the hose run short, use proper fittings and route lines away from heat and sharp edges. Some owners add an inline filter and a moisture drain to keep the solenoid clean.
Consider installation. Carrier removal, gear setup and backlash adjustment require experience. A qualified differential shop can do the job correctly, and many owners find that the labor cost is worth the peace of mind. If you do it yourself, follow the service manual exactly and check the gear pattern before reassembly.

FAQ
Does the ARB Dana 60 air locker fit a Dana 44?
No. It is designed for the Dana 60 housing and ring gear. Dana 44 and Dana 35 axles use different carriers, so check the axle code and housing size before ordering.
Do I need a compressor to run an air locker?
Yes. An air locker requires a compressed air source. Most owners use a 12-volt compressor, sometimes paired with a tank, and a regulator to hold steady pressure.
Can I drive on pavement with the locker engaged?
You should not. A full locker prevents the wheels from turning at different speeds, which causes tire scrub, binding and handling problems on road. Disengage it before driving on pavement.
How fast does the locker engage?
Engagement time depends on compressor output, hose length and pressure. Owners often report that a short, well-sized air system locks quickly, while long runs or weak compressors can slow engagement.
Is installation something I can do at home?
It is possible for experienced mechanics with the right tools and a service manual, but carrier removal and gear setup are demanding. Many owners choose a professional shop, especially for the first install.
Does the locker need regular maintenance?
Owners generally recommend checking the differential fluid on schedule, inspecting air lines for leaks, draining moisture from the air system and confirming the solenoid operates cleanly. Follow the manufacturer’s maintenance intervals.
Will a locker damage my axle shafts?
A locker increases torque transfer to both shafts, which can stress weak components under hard use. Many owners pair lockers with stronger shafts, especially on high-torque or heavily modified rigs.
Final Verdict
The ARB Dana 60 air locker is a solid, driver-controlled traction upgrade for Dana 60 owners who take their vehicles off pavement and want locking power on demand. Its air actuation is clean and dependable once the system is properly built, and its full-locking design delivers real traction on climbs and uneven ground. The tradeoffs are real: you must maintain an air system, install the carrier carefully and remember to disengage before road driving. If that fits your build, it is a strong choice. Check fitment and read the installation sheet, then consider View on Amazon as your starting point.
