A single-axle trailer has just two brakes, so the controller is working with the lightest electrical load it will ever see. That changes the buying question: you are less likely to need an eight-brake rating and more likely to need a clean, correct hookup.

Four controllers and two vehicle harnesses made this list, sorted by how well their listings describe small-trailer use. Check the stated axle range on every one, because one title here says 2-4 axles while its own bullet says 1-4.

RV Gear Lab field notes

The Rig Fit Check

Start with the job: Lrichy 90160 Proportional Trailer Brake Controller for 1-3 Axles leads this shortlist for Single-axle trailers with a simple dash install. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks: The first details to compare are Proportional, 1-3 axles, Proportional, self-leveling. Confirm the exact model and included components before ordering.
Trade-off to plan for: Clone of Tekonsha Primus IQ

Before you buy

What Matters Before You Choose a Trailer Brake Controller For Single Axle Trailer

Key buying criteria so you get the right fit the first time.

01
Axle range minimum
Some controllers list a minimum of two axles, which can mean they are not designed for a single-axle trailer. A controller that expects more load can read a two-brake trailer as a fault. Check both the title and the bullets, as the CURT TriFlex lists them differently.
02
Two-brake current draw
Each brake adds a magnet, so a single-axle trailer draws less current than a tandem. Controllers rated for up to eight brakes can handle it, but some of the extra capacity is wasted. Compare brake counts on listings, such as 2, 4 or 6 on the Lrichy 90160.
03
Proportional versus timed
A proportional controller brakes in step with your deceleration, giving smoother stops with a light trailer. Time-delay gives a fixed ramp. Check for words like inertia sensor on the listing.
04
Mounting and leveling
Some older proportional controllers have to be level. If you tow with several vehicles, self-leveling helps. The LAJBZ 1-3 and Orvex 90160 both list it.
05
Vehicle harness match
A controller still needs the right connector for your truck. A harness for Ford, GM or Sprinter vehicles is usually sold separately. Check your vehicle against the harness listing, like the Oyviny 3036-P Ford list.
06
Warranty wording
Clone makers state terms differently, such as a two-year warranty or vague lifetime service. A specific term is easier to hold the seller to. Look for the number of years in the guarantee bullet.

The 6 best trailer brake controller for single axle trailer, explained

Best Overall · 1 of 6

Lrichy 90160 Proportional Trailer Brake Controller for 1-3 Axles

Proportional, 1-3 axles
2, 4 or 6 brakes
Clip and bracket included

Check price on Amazon

Best for: Single-axle trailers with a simple dash install

Our take

Best for a single-axle camper or utility trailer where you want proportional stops and a simple install.

Why it made the shortlist

The Lrichy 90160 is a proportional controller for 1-3 axles that supports 2, 4 or 6 brake trailers. It uses internal inertia sensors, has an LED display and includes a snap-in dash clip, an adjustable-angle bracket and a plug-and-play port for two plug adapters.

It is sold as a replacement for the Tekonsha 90160 Primus IQ, so it is a clone, with a two-year warranty. Against the Orvex 90160 below it adds the mounting hardware and a stated two-year warranty, while the Orvex leans on a lifetime-service claim.

Both axle limits are right for a two-brake trailer, so you are not paying for capacity you will not use.

What works

Proportional braking from inertia sensors
Includes dash clip and angle bracket
Two-year warranty stated on listing
Removable connector for easy storage

Watch out for

Clone of Tekonsha Primus IQ
Capped at three axles
Vehicle harness is separate

Check price on Amazon

Best Self-Leveling · 2 of 6

Proportional Trailer Brake Controller for 1-3 Axles

Proportional, 1-3 axles
Self-leveling sensor
Multiple boost levels

Check price on Amazon

Best for: Utility or boat trailers on mixed vehicles

Our take

Best for a boat or utility trailer you move between vehicles with different dash angles.

Why it made the shortlist

The LAJBZ proportional controller is listed for 1-3 axle trailers with 12V electric brakes. It self-levels, has multiple boost levels and a bright digital display showing output level, trailer connection and diagnostics.

It is a replacement-style unit like the rest, not a name brand.

What works

Self-leveling, so no mounting angle fuss
Multiple boost levels for loaded trailers
Display shows output and diagnostics
Suited to RVs, boats and utility trailers

Watch out for

Listing gives no warranty length
Replacement-style, not a major brand
Harness sold separately

The catch: Compared with the Lrichy 90160 it has no listed brake-count range or warranty, but it describes itself as ideal for RVs, campers, boats and utility trailers.

Check price on Amazon

Best Value Proportional · 3 of 6

Orvex Universal Trailer Brake Controller

Proportional, self-leveling
Manual override, three boosts
Clip or bracket mount

Check price on Amazon

Best for: Flexible dash mounting

Our take

Best for buyers who want a clip or bracket mount with 180-degree range and a manual override lever.

Why it made the shortlist

The Orvex Universal controller is listed as a replacement for Tekonsha 90160. It has proportional braking, a digital display, a manual override lever, three boost settings and self-leveling technology.

Its listing text is nearly identical to the HRepair 90160, so it is part of the same clone family.

What works

Manual override lever for emergency braking
Self-leveling, mounts in 180-degree range
Three boost settings tune braking power
Circuit protection built in

Watch out for

Listing gives no axle range
Clone-style replacement
Lifetime service terms are vague

The catch: Against the Lrichy 90160 it is a bit pricier and says lifetime service and a no-hassle return policy rather than a stated warranty term.

Best Brand-Name Option · 4 of 6

CURT 51146 TriFlex Next Proportional Inertia Electric Trailer Brake Controller

Triple-axis accelerometer
Hill-aware power adjustment
Listed 1-4 axles in bullets

Check price on Amazon

Best for: Single axle now, tandem later

Our take

Best if you plan to upgrade to a tandem later and want a CURT controller now.

Why it made the shortlist

The CURT TriFlex Next is a proportional inertia controller with a triple-axis accelerometer, and the third axis adjusts power on hills. The title says 2-4 axles while one bullet says 1-4 axles and operates 2-8 brakes.

What works

Third axis adjusts power on hills
Low-profile design clears the dash better
Major-brand controller
Room to grow if you add an axle

Watch out for

Title says 2-4 axles, bullet says 1-4
Priciest controller in this list
More capacity than a single axle needs

The catch: That conflict is the main catch for a single-axle trailer.

Best Sprinter Harness · 5 of 6

AKLOSIPY Trailer Brake Controller Custom Harness Reliable Wiring Kit for Sprinter 2500 3500 Plug and Play Inst

Sprinter 2007-2021 fits

The AKLOSIPY harness is a plug-and-play connector for Sprinter 2500 and 3500 vans, listed for 2500 2007-2009 and 3500 2007-2021 years. It lists reference part number 306300 and weatherproof terminals.

Compared with the Oyviny 3036-P below it targets a van platform rather than Ford trucks.

What works

Plug and play, no splicing
Matches a named reference part number
Weatherproof housing and terminals
Copper conductors for clear signals

Watch out for

Fits only listed Sprinter years
Not a controller by itself
Model year gaps in listing

Its list names Draw-Tite Activator and Tekonsha controllers, so pair it with a controller that has a matching plug.

What works

No cutting or splicing needed
Wide Ford model-year coverage
Standard 4-pin connector
Durable ABS plastic and copper terminals

Watch out for

Fits only listed Ford years
Not a controller by itself

Methodology

How We Built This Shortlist

Each pick was assessed across 5 criteria weighted for real-world use.

Small-trailer fit

We compared stated axle and brake ranges to judge which listings suit a two-brake single-axle trailer without paying for unused capacity.

Braking behavior

Proportional control was weighed against simpler designs, with attention to hills and light-trailer stops.

Mounting freedom

Self-leveling and bracket options were compared, since a single-axle trailer is often towed with multiple vehicles.

Harness coverage

The two harnesses were scored on the vehicles their listings name, not on controller features.

Listing clarity

Conflicting or missing details, like an axle range that differs between title and bullet, were noted as buyer risks.

Decision guide

Match a Trailer Brake Controller For Single Axle Trailer to Your RV

By Single-Axle Trailer Type

Your situation	Recommended pick	Why
Small camper or cargo trailer	Lrichy 90160	Proportional, 2-6 brakes, clip and bracket included.
Boat or utility trailer on several vehicles	LAJBZ 1-3	Self-leveling suits different dash angles.
Light trailer, wants manual lever	Orvex 90160	Manual override lever and three boost settings.
May add a second axle later	CURT TriFlex	Handles up to eight brakes, if single-axle use is confirmed.

By Budget

Budget	Recommended pick
$10 to $30	Oyviny 3036-P or AKLOSIPY Sprinter
$60 to $70	Lrichy 90160 or Orvex 90160
$70 to $150	LAJBZ 1-3 or CURT TriFlex

Brand Name vs Clone Pricing

Brand name

A major brand offers clearer support and engineering. The CURT TriFlex is the one example.

Clone replacement

Cheaper units like the Lrichy 90160, LAJBZ 1-3 and Orvex 90160 copy Tekonsha designs and carry the seller's own terms.

For a single-axle trailer, most buyers should default to the Lrichy 90160.

By Tow Vehicle

Tow vehicle	Recommended pick
Sprinter 2500 or 3500	AKLOSIPY Sprinter
Ford F-150 or Super Duty	Oyviny 3036-P
Other vehicles with a factory port	Lrichy 90160
Multiple vehicles	LAJBZ 1-3

For Small Utility Trailers Specifically

Look for

A 1-axle rating, 2-brake support and a simple install, as on the Lrichy 90160 or LAJBZ 1-3.

In this comparison

Lrichy 90160 states 2, 4 or 6 brakes and includes a bracket, while LAJBZ 1-3 self-levels. The CURT TriFlex is more than most single-axle owners need.

When to Spend More

Spend more if

Spend more on the CURT TriFlex only if you plan a tandem later or want a major brand. Otherwise the cost is hard to justify on two brakes.

Save if

Save with the Lrichy 90160 or Orvex 90160 and spend the difference on the right vehicle harness, such as Oyviny 3036-P.

FAQ

Before You Bring One Home

Do single-axle trailers need a brake controller?

Only if they have electric brakes. Many small trailers do not. If yours does, you need one, and many states set brake rules above about 3,000 pounds.

What mistake do buyers make?

Buying a controller with a 2-axle minimum or skipping the vehicle harness. Read both the title and the bullets.

Is the CURT TriFlex worth it over the Lrichy 90160?

Only if you need hill-aware braking or room for more axles. For two brakes, the Lrichy 90160 does the job for much less.

How do I set it up?

Plug in the harness, mount the controller, then adjust gain on a dry level road so the trailer stops firmly without locking up.

Can I move the controller between trucks?

Yes, if each truck has a matching harness. The LAJBZ 1-3 is self-leveling, which helps since dash angles differ.
