The spray in bedliner vs drop in decision comes down to one trade: a drop in liner is a moulded plastic shell that costs less and lifts out, while a spray in liner is a coating bonded to the bed that stays put and leaves no gap underneath for water and grit. For a truck that hauls gravel in summer, grain bags at harvest and road salt all winter, the spray in liner is the stronger choice. For a truck that carries light loads, or one you plan to trade soon, a drop in liner is a fair one. Before you pick, ask our parts department whether they can order or arrange one for your truck, with your model year, cab and box length in hand.
A Manitoba box goes through a lot in one year: crushed rock for the yard in June, seed and feed bags in spring and fall, and slush full of road salt that drifts in over the tailgate from November to April. If you are not sure which box your truck has, our Ram 1500 bed size guide covers the 5 foot 7 and 6 foot 4 boxes.
Key Takeaways
- A drop in liner costs less and lifts out, but salt water and grit can collect between it and the bed and wear the paint where it rubs.
- A spray in liner is bonded to the bed and grips a load, but it is permanent, and the result depends on how well the bed was prepared.
- A new truck may already have one. Check the optional equipment on a new Ram's window sticker for a Mopar spray in bedliner before you arrange a liner.
- RamBox changes the part. A drop in liner for a RamBox truck has to be made for the RamBox box; ask our parts department for the one that fits your model year.
- At trade time, an appraisal looks at the paint under a drop in liner, and at the condition of a spray in coating itself.
The Three Options at a Glance
The table sets the two liner types side by side, with a third row for a Mopar spray in liner already on a new truck.
| Option | How It Goes In | Winter Weak Point | Who It Suits |
|---|---|---|---|
| Drop in liner | A moulded plastic shell set into the box | Salt water and grit underneath; a slick floor when frosted | Light loads, or a truck you may trade soon |
| Spray in liner | A coating sprayed onto a prepared bed | Poor prep can let the coating lift at the edges | A box that works all year |
| Mopar spray in, on a new truck | Listed in the truck's optional equipment, where it is fitted | The same as any spray in coating | A new truck that already has it; ask our team whether it can be ordered on your build |
How a Drop In Liner Works, and Where It Falls Short
A drop in liner is a single moulded piece that sits in the box. Mopar's own drop in bedliner for the Ram 1500 is moulded from a high density polyethylene blend, with ribs that Mopar says help keep cargo from shifting and promote drainage, and a tailgate liner included.
The strengths are real. It takes a shovel or a load of rock without much to show for it, and it lifts out when you want the bare box back.
The weak point is the space underneath. A drop in liner sits on the bed rather than bonding to it, and drainage does not stop fine grit and salty water from working into that space on gravel roads. Each time a load shifts, the liner moves a little against the paint. Over a few winters that can wear through to bare metal, and bare metal left wet with salt can rust where nobody is looking.
The other catch is grip. A hard plastic floor can be slick, and on a frosty morning at minus 30 a toolbox or a stack of feed bags can slide toward the tailgate.
If you go this way, lift the liner out in spring and fall, rinse the salt out of the box, and let it dry before the liner goes back in.
How a Spray In Liner Works, and Why Prep Matters
A spray in liner is a polyurethane or polyurea coating sprayed directly onto the bed. It bonds to the surface and follows the ribs, corners and wheel wells, so there is no space underneath for water or grit to sit in.
That is why it suits a Manitoba truck. The textured surface grips a load, so grain bags and coolers stay where you put them. Salt slush sits on top of the coating, not between a liner and the paint, and a hose takes it off.
The catch is that it is a coating job, and the result depends on the prep. The bed has to be cleaned and the paint scuffed so the coating has something to hold. Skip that, and a coating can lift at the edges and let water in behind it. Ask how the bed will be prepared before you agree to any spray in job.
It is also permanent, so be sure it is the finish you want for the life of the truck.
Buying New: Check the Window Sticker
If you are buying new, you may not need to arrange a liner afterward. When you browse our new Ram 1500 inventory or new Ram 2500 inventory, check the optional equipment on each window sticker for a Mopar spray in bedliner. If you are ordering a truck, ask our team whether a spray in bedliner can be ordered on your build.
Gravel, Grain and Road Salt: What Each Liner Goes Through
Gravel and rock. A shovel scraping across the floor is where a plastic liner earns its place, because it takes the scrape instead of the paint. A spray in coating handles it too, though a sharp shovel edge can scuff the texture over time.
Grain and feed bags. This is the spray in liner's best case. The textured floor holds bags in place, and spilled grain has nowhere to hide. Under a drop in liner, chaff and spilled grain can work into the gap along with the grit.
Road salt. From freeze up to spring melt, snow drifts into an open box and salt rides in with it. On a spray in liner, a rinse clears it. A drop in liner has to come out to clear what is underneath.
RamBox and the Tailgate
For the 2026 Ram 1500, Ram Canada lists the available class exclusive RamBox cargo management system, storage bins built into the box sides. That changes the liner. A drop in liner for a RamBox truck has to be made for the RamBox box, so a liner made for a conventional box is the wrong part; ask our parts department for the one that fits your model year and box length. A spray in coating is applied to whatever shape the bed has. Our post on the Ram 1500 RamBox explains the system and the bed accessories it affects.
Don't forget the tailgate. Loads slide over it, and it collects salt along its lower edge all winter. Mopar includes a tailgate liner with its drop in bedliner. For a spray in job, ask whether the inside of the tailgate is part of the coating. If you also plan a cover, our tonneau cover guide for the Ram 1500 walks through the five types.
The Resale Read When You Trade
When a truck is appraised, the bed gets a look. A drop in liner lifts out, and what gets judged is the paint under it: a clean, dry bed reads well, and rust spots where the liner rubbed do not. A spray in liner stays with the truck, so its own condition is what gets judged. An intact coating reads as a protected bed, and a coating lifting at the edges raises the question of what is underneath.
Our advice: rinse the box before an appraisal, and pull a drop in liner out so the bed underneath is dry. Our post on Ram 1500 depreciation and resale in Manitoba covers the bigger factors that move a number.
Spray In Bedliner vs Drop In: Which One Your Bed Needs
Choose a spray in liner if the box works all year, carries bags or loose loads that should not slide, and sees salt every winter. Choose a drop in liner if the loads are light, the budget is tight, or you want the bare box back when you sell, and plan to lift it out to clean underneath twice a year. If you are buying a new truck, check its window sticker for a Mopar spray in bedliner first.

FAQs
Is a spray in bedliner better than a drop in?
For a Manitoba truck that hauls all year, a spray in liner is the stronger choice when the bed is properly prepared, because it is bonded to the bed and leaves no gap for salt water and grit to collect. A drop in liner costs less up front and lifts out, which suits light loads or a truck you plan to trade soon.
Can a drop in liner damage the paint in the bed?
It can. Water, salt and grit that collect between the liner and the bed can wear the paint where the liner rubs, and bare metal left wet with salt can rust. Lift the liner out in spring and fall, rinse the box and let it dry.
Can a new Ram be ordered with a spray in bedliner?
Ask our team whether a Mopar spray in bedliner can be ordered on your build. On a new truck already in stock, check the optional equipment on its window sticker for that line.
Does a drop in liner fit a Ram 1500 with RamBox?
Only one made for it. A drop in liner for a RamBox truck has to be made for the RamBox box, so ask our parts department for the one that fits your model year and box length. A spray in coating is applied to the bed itself, whatever its shape.
Does Dunn Ram Trucks install bed liners?
Ask our parts department whether they can order or arrange a drop in or spray in liner for your truck. Bring your model year, cab, box length and whether the truck has RamBox.
The Bottom Line
A drop in liner protects the bed from the shovel but can hold salt and grit against the paint. A spray in liner grips the load and seals the bed, as long as the prep is done right. For a truck that works through a Manitoba winter, the spray in liner is the safer bet; for light use, a drop in liner with a clean out twice a year is a fair one. At Dunn Ram Trucks in Portage la Prairie, start with our parts department, and ask which bed liners they can order or arrange for your truck.
