(To level your trailer correctly, subtract your trailer’s coupler height from your truck’s receiver height. The difference is the “drop” you need. If unsure, round up slightly or choose an adjustable drop hitch for flexibility.
Quick Guide: Get the Right Drop Hitch Without Guesswork
To avoid trailer sway, braking issues, and jack damage, your trailer needs to be level. Here’s the fast, no-nonsense way to figure it out:
-
Step 1: Park both truck and trailer on level ground.
-
Step 2: Measure from the top of your truck’s receiver to the ground.
-
Step 3: Measure from the bottom of your trailer’s coupler to the ground.
-
Step 4: Subtract coupler height from receiver height to find your drop.
Need to round? Go slightly higher. Towing with a loaded trailer? Always measure when it’s packed. Have more than one trailer? Adjustable is your friend.
Even a 1–2" misfit can cause sway, scrape driveways, or wear your tires unevenly. Measure once, tow right. And if your setup looks “close enough,” it probably isn’t.
That said, there’s more to this than just math.
Stick around and we’ll walk you through real mistakes, flexible hitch options, and the one measurement that most people get wrong, so your trailer stays secure, smooth, and safe mile after mile.
Before You Buy Anything, What a Drop Hitch Really Does
So, you're staring at your truck and your trailer, wondering why they don’t quite line up, and maybe asking yourself:
Do I even need a drop hitch? Let’s start with the basics and clear the air.
What Exactly Is a Drop Hitch?
Think of a drop hitch as an adjustable bridge between your truck and trailer. It slides into your truck’s receiver and holds the hitch ball at the right height to keep your trailer level.
The "drop" refers to how far down the ball sits from the receiver.
If your trailer coupler is lower than your truck's receiver, you'll need a drop hitch.
If it's higher (which is rare, but possible), you'd go with a rise. Most people driving modern trucks, with or without a lift, end up needing a drop.
Why Level Matters More Than You Think
A level trailer isn’t just about looks, it’s about safety.
When your trailer rides nose-up or nose-down, weight distribution gets thrown off.
That can lead to trailer sway, poor braking, uneven tire wear, and even frame damage. We've seen jacks get ripped off and safety chains drag down the road, all because the hitch height was just a bit off.
Lifted Truck? Bigger Tires? You’re Gonna Need Drop
If you’ve installed a lift or upgraded to 35” tires, you almost definitely need a drop hitch. But here’s where people get tripped up, just because you added 3" of lift doesn’t mean you need exactly 3" of drop.
Why?
Because tire diameter, trailer coupler height, and even rear suspension sag under load all play a role. The only way to know for sure is to measure (we’ll walk you through that in the next section).
Trust us, guessing leads to scraping hitches and twisted axles.
Ready to figure out your exact size? Let’s get into how to measure it properly, without the guesswork.
How to Measure Your Setup in 5 Minutes or Less
Here’s the truth: if you can measure a fence post, you can measure for a drop hitch. This part’s simple, but often skipped, and that’s what leads to mismatches. Let's fix that in five minutes flat.
Step 1: Get Your Truck and Trailer on Level Ground
Before you grab your tape measure, make sure your vehicle and trailer are on a flat, even surface. Gravel driveways, sloped garages, or uneven pavement can throw off your numbers.
Pro tip: We’ve had customers send photos from slightly slanted garages, thinking they needed an 8” drop, when a 6” was perfect. Flat ground matters.
Step 2: Measure Receiver Height
Grab your tape measure and hook it to the inside top edge of your truck’s receiver opening (not the ball mount). Measure straight down to the ground. That number is your receiver height.
Example: Your receiver height is 24".
Step 3: Measure Coupler Height
Now go to your trailer. Measure from the bottom of the coupler (the part that drops over the ball) straight down to the ground.
Do this when the trailer is level and loaded the way you normally haul it, coolers, gear, tools and all. That’s crucial.
Step 4: Subtract to Find Your Drop (or Rise)
Now subtract your coupler height from your receiver height.
-
If your receiver is higher, the result is your needed drop.
-
If your trailer is higher, that number becomes your needed rise (less common).
Example:
-
Receiver height = 24"
-
Coupler height = 18"
-
Needed drop = 6"
Round to the nearest inch.
If you're between two numbers (say, 5.25"), lean slightly toward the larger size or opt for an adjustable model.
Bonus Considerations
-
Lifted trucks compress rear suspension when towing, what looks level while parked may sag 1–2" under load.
-
Airbags or load-leveling kits? Measure with them inflated to your towing setting.
-
Aftermarket bumpers or towing setups can shift the receiver height more than you'd think.
A properly measured drop hitch isn’t just more comfortable, it’s safer, smoother, and keeps your gear where it belongs: on the road. Take five minutes now, save yourself hours later.
AND… if your measurements landed somewhere between two sizes, or if your setup might change down the line, you’re not alone.
That’s exactly where adjustable drop hitches shine.
They give you the flexibility fixed hitches just can’t, especially when your trailer isn’t the only thing that changes.
Let’s take a closer look at why spending a little more upfront on an adjustable setup can save you time, hassle, and extra trips to the store.

Why Adjustable Drop Hitches Are Worth the Extra Cost
Adjustable drop hitches cost more upfront, but that extra spend isn’t just for convenience, it’s for versatility, durability, and peace of mind on the road.
Here’s what makes them a smart investment.
1. They Handle More Than One Trailer or Setup
A fixed hitch works great when everything stays the same.
But if your trailer types, loads, or truck height change even a little, an adjustable hitch keeps you towing level without swapping hardware.
2. They Future-Proof Your Tow Rig
From seasonal gear loads to unexpected lift kits, adjustable hitches offer flexibility for what’s ahead. No need to buy a new hitch every time your setup changes, just slide the ball mount to the right height.
3. They Come in Materials That Match Your Environment
Steel is great for strength and durability under stress.
Aluminum is lightweight and corrosion-resistant, ideal for coastal haulers or those who tow through winter road salt. Choose what fits your use case best.
4. They Can Rattle, But There’s an Easy Fix
Rattle is common in adjustable hitches, especially when towing light loads.
Anti-rattle pins and clamp kits help lock everything tight for a quieter, smoother ride with less wear over time.
5. They’re Built to Last, If You Use Them Right
Yes, aluminum models may loosen slightly under heavy, repeated use.
But with regular checks and proper pairing to your load, adjustable hitches can serve for years, and save you from buying more than one.
Adjustable hitches solve a lot of the common fit issues people run into, but only if you know how to choose and use them correctly.
The real trouble starts when folks skip the measuring step or rely on bad advice.
Here’s where most towing setups go wrong, and how to avoid those same costly mistakes.
Six Mistakes That Lead to the Wrong Hitch (And a Bad Tow Day)
Getting the wrong drop hitch isn’t just a minor inconvenience, it can wreck your trailer setup, damage gear, and turn towing into a safety hazard.
Here are six common mistakes to avoid:
-
Matching lift height to drop size: A 4" lift doesn’t mean you need a 4" drop. Tire size, trailer height, and suspension sag all factor in.
-
Copying someone else’s setup: Even if you have the same truck, your trailer, load, and accessories make your hitch needs unique.
-
Overbuying for future mods: Buying a 10" drop for a future lift can reduce ground clearance today, causing scraping or jack damage.
-
Measuring with an empty trailer: Tongue weight compresses suspension. Always measure when the trailer is loaded as it would be during travel.
-
Wrong receiver shank size: Know whether your truck uses a 2", 2.5", or 3" receiver. Using adapters can cause wobble and wear.
-
Assuming all “6-inch drop” hitches are equal: Weight capacity, adjustability, materials, and ball mount type vary widely, even if the drop height matches.
Measure carefully, buy for your current setup, and double-check specs before you tow. Avoiding these mistakes can save you from a costly, and potentially dangerous, tow day.

Still Not Sure? Here’s the Proven Way to Nail It First Try
If you're on the fence about what drop size to buy, here’s how to keep it simple and avoid a costly mistake:
-
Go slightly larger if unsure. If your measurement falls between sizes, rounding up (within reason) helps account for load sag or uneven terrain.
-
Choose adjustable for flexibility. It’s a smart choice if you tow multiple trailers, plan to lift your truck, or want one hitch to handle everything.
-
Avoid “eyeballing” your setup. A trailer that looks close might still ride nose-up or down once loaded, measurement beats guesswork every time.
