If you buy one piece of sill protection for a Model Y, buy the trunk sill cover. The rear sill is a painted body edge at the mouth of the cargo opening, and every heavy or awkward thing you load - a case, a crate, a bag of compost, a dog - gets dragged across it. Door sills get stepped on, which is abrasion. The trunk sill gets scraped by hard objects under load, which is paint damage, and paint damage on a body edge is expensive and visible.
The frustrating part is that most sill protector sets are sold as door sill sets and stop at the four door openings. The piece covering the surface that takes the worst treatment is the piece most often missing from the box, which is why this page exists and why only one of the picks below is really the answer to it.
Why the trunk sill is the worst-treated edge in the car
| Surface | What touches it | Type of damage | Visible from outside? |
|---|---|---|---|
| Front door sills | Shoes, trouser hems, occasional bag | Scuffing and dulling | Only with the door open |
| Rear door sills | Children's shoes, child-seat feet | Scuffing, sometimes scratching | Only with the door open |
| Trunk sill | Everything loaded, dragged under its own weight | Scratches to paint on a body edge | Yes, every time the liftgate opens |
| Rear bumper top face | Knees, bags set down mid-lift, the dog | Scratches and scuffs on paint | Yes, always |
The bumper row matters as much as the sill row, and the two are usually bought together for a reason: a load coming out of the trunk crosses the sill and then the bumper top face, and the second one is painted bodywork that is visible whether the car is open or closed. If you are protecting one, protect both.
What to look for
- Does the set actually include a trunk sill piece? Read the piece count and the piece list, not the title. Four pieces means door sills only.
- Does it name your generation? The Juniper's cargo aperture differs from the 2020-2024 car's, and several sets are listed for one and not the other - some only for five-seat layouts.
- How is it held on? Nearly everything in this category is adhesive, which is the trade you accept for a part on a body edge. Look for a no-drill install and a stated install time.
- Does it cover the full width of the sill, or just the center section? A short piece protects where you look and not where the corners of a crate land.
- Material. ABS is hard and takes the scrape; TPE flexes and stays quieter. On a trunk sill, hard is usually the right answer.

1. The only set with the trunk sill in it
BestEvMod 5-piece door sill protector set
Five pieces: front sills, rear sills, rear bumper and a trunk sill cover, listed for the 2026 Model Y, in ABS. The reason it leads this page is simply that it includes the piece the page is about - most sill sets stop at the four door openings. ABS is a hard plastic, so it protects by taking the scrape itself rather than by flexing.
Best for: Covering sills, rear bumper and trunk sill in one purchase
Fits: Model Y Juniper (2025-2026)
What works
- The widest piece count here — the trunk sill is a genuinely vulnerable painted edge
- One order rather than sourcing bumper pieces separately
What does not
- Rigid ABS can lift at the ends on a curved sill where TPE would follow it
- Five adhesive pieces means five chances to get the alignment wrong
Manufacturer specifications
- Five pieces: front sills, rear sills, rear bumper and trunk sill cover
- Listed for the 2026 Model Y
- ABS construction

2. Best bumper coverage
QINQINTU carbon-fiber-finish door sill protector set
Carbon-fiber-pattern finish over an ABS substrate, with front and rear sills plus bumper guard pieces, listed for Juniper 2025-2026 Premium and Performance trims; the manufacturer quotes roughly a twenty-minute no-drill install. The bumper pieces are the ones that matter here - the top face of the rear bumper is what your knees and bags hit on the way in.
Best for: Juniper Premium and Performance owners who want full sill and bumper coverage
Fits: Model Y Juniper (2025-2026)
What works
- The rear bumper lip is where almost all real loading damage happens, and this set actually covers it
- No drilling and no permanent modification
- Trim-specific listing rather than a generic Model Y part
What does not
- Carbon-fiber pattern is a strong look that will not suit every car
- Adhesive-backed trim is the hardest kind to remove cleanly years later
Manufacturer specifications
- Carbon-fiber-pattern finish over an ABS substrate
- Set includes front and rear sills plus bumper guard pieces
- Listed for Juniper 2025-2026 Premium and Performance trims; manufacturer quotes roughly a twenty-minute no-drill install
Specifications as published by the manufacturer. We have not independently tested this product.

3. Best low-profile option
Lasfit matte TPE door sill protector
Matte TPE rather than glossy plastic or metal, shaped to the Model Y sill profile, front and rear pieces. Door sills only, so it is not the trunk-sill answer - it is here because if you have decided to cover the door openings as well, matte TPE is the finish that does not announce itself in a car with a dark interior.
Best for: Owners who want sill protection nobody notices
Fits: Model Y (2020-2024) · Model Y Juniper (2025-2026)
What works
- Matte black disappears against the factory trim — the opposite of the carbon-fiber look
- TPE flexes over the sill curve instead of lifting at the ends like rigid trim does
- Grippier underfoot in the wet than a smooth plastic sill cover
What does not
- No bumper or trunk-sill pieces in the set
- Matte TPE holds dust more visibly than a gloss finish
Manufacturer specifications
- Matte TPE rather than glossy plastic or metal
- Front and rear sill pieces
- Shaped to the Model Y sill profile
Specifications as published by the manufacturer. We have not independently tested this product.

The alternative, which is sometimes better
Clear paint protection film does the same job invisibly. On a painted sill the argument for film is strong: it follows the curve exactly, it does not add a visible plastic line to the back of the car, and it can be removed professionally without taking the paint with it. The argument against is that it is thinner than a plate, so it resists scratching rather than impact, and a crate corner dropped onto a filmed edge can still dent what is underneath.
Door sill film versus sill plates sets that trade-off out in full, and it applies to the trunk sill more than to any door sill, because this is the edge where both the damage and the cure are most visible. For most owners who load the car regularly, a plate is the pragmatic answer - it is the part that takes the hit instead of the paint.
Our call
Buy a set that includes the trunk sill cover, and buy the bumper pieces with it. Those two surfaces are where visible damage happens in this car, and they are the surfaces a four-piece door sill set does not touch. If your set is listed for the 2026 Model Y and lists its pieces individually, you are buying from a brand that understands the problem.
Door sills are worth covering too, but they are the second purchase, not the first - the damage there is dulling rather than scratching and it happens far more slowly. The Model Y door sill roundup covers that side of it, and carbon fiber versus stainless is the material decision if you want the sills to be a visible upgrade rather than invisible protection.
Questions people actually ask
What is a trunk sill protector?
A cover for the painted body edge at the mouth of the cargo opening - the strip everything you load gets dragged across. It is a different part from a door sill protector, and most door sill sets do not include it.
Is the trunk sill the first sill to protect?
Yes, for anyone who loads the car regularly. Door sills get scuffed by shoes, which dulls them slowly. The trunk sill gets scraped by hard objects under load, which scratches paint on an edge that is visible every time the liftgate opens.
Do trunk sill protectors need adhesive?
Nearly always, because there is nothing to clip to on a body edge. Clean the surface properly, fit it warm and dry, press it down and leave it for a day. Adhesive applied to a cold or waxed edge is why these parts lift at a corner.
Film or a plate for the trunk sill?
A plate, for most owners who load the car often - it takes the scrape instead of the paint. Film is the better choice if you want the protection to be invisible and your risk is scratching rather than impact.
Will a 2020-2024 Model Y sill set fit a Juniper?
Not reliably. The cargo aperture and sill lengths differ, and several sets are listed for one generation only - some for five-seat layouts only. Buy the set that names your car.
