Too flat, too high, not fine-tuned, or too tight: four fixes.
Stock JL seats don’t fit everyone the same way, and the complaints aren’t interchangeable.
You might find that the seat is too flat, too high, not fine-tuned enough on the angles, or that you just need more legroom entirely.
Four different problems, one shared complaint: a relentlessly uncomfortable seat.
Seat Jackers for Jeep JL and similar products exist to fix exactly this Jeep Wrangler uncomfortable seating position problem, matched to whichever specific complaint is actually yours.
The products and what they fix:
- Front Seat Jackers: Bolt-on spacers that tilt the front of the seat up. No cutting required.
- Seat Slammers: Blocks that drop the rear of the seat down. Requires cutting the seat’s mounting legs, a permanent modification.
- Adjustable Rear Seat Jackers: Fine-tunes the rear mounting point after Front Jackers are installed. Bolt-on, no cutting.
- Seat Extenders: Moves the whole seat back for more legroom. No cutting.
Here’s a deeper dive on what each one does, plus fitment and pricing.
1. Front Seat Jackers: The Flat Seat Fix
Front Seat Jackers are simple aluminum blocks that bolt between the seat and its factory rails, tilting the whole seat up for better thigh support.
Several companies make them for the JL, but Desert Does It Front Seat Jackers have an established owner track record and inseam-based fit data, so they’re the version covered here.
The Seat Jackers Desert Does It sells are machined from aircraft-grade 6061 aluminum with a satin black powder coat. They come in two versions, Fixed and Shorty, the difference is how much lift each one gives and who it’s built for.
Desert Does It’s Fixed Front Seat Jackers lift the front of the seat 1.25 inches, sized for a driver or passenger with a 36 to 38 inch inseam. They bolt to the factory seat rails, no cutting required.
Desert Does It’s Shorty Front Seat Jackers lift the front 0.75 inches, sized for a driver or passenger with a 28 to 34 inch inseam who doesn’t need the full lift. Same bolt-on install.
Jeep JL seat jackers and Jeep JL front seat risers are the same part, different name. Both fix the same flat-seat, no-thigh-support complaint, just calibrated for different heights. Get the inseam right and either one solves it.
2. Seat Slammers: The Headroom Fix
While seat jackers raise the front of the seat, seat slammers do the opposite.
A Jeep JL seat slammer kit is built around that exact complaint: rear-mounting blocks that drop the back of the seat down, aimed at taller drivers who feel like they’re sitting too high in the cabin.
Desert Does It Seat Slammers are the option to consider for drivers over 6’2″. These seat slammers Jeep JL owners rely on come with a lifetime warranty on the hardware itself.
Two kit options exist. Option 1 drops the rear 0.5″ to 1.5″. Option 2 drops the rear 0.5″ to 2″, and already includes the 0.75″ Shorty Front Seat Jackers needed to lift the front and reach the full drop.
Both options require cutting the seat’s rear mounting legs to install.
For taller drivers who technically fit the Jeep but aren’t comfortable in it, Slammers solve a persistent too-tall-for-the-cabin problem. They gain headroom along with a seating position that doesn’t feel like sliding forward under braking.
A few install specifics worth knowing: on 2-door JL, drilling the outer leg requires care to avoid the seat rail’s stop rivet. A full 2″ drop with the seat pushed all the way back can also cause it to rub the B-pillar, per the manufacturer’s product page.
The passenger-side install requires relocating a ground stud that’s otherwise in the way.
3. Adjustable Rear Seat Jackers: The Fine-Tuning Fix
Some owners don’t need a full fix, just fine-tuning: spacers that go under the rear bolts of the front seat, adjusting the angle, usually paired with Front Jackers rather than bought alone.
Desert Does It’s Adjustable Rear Seat Jackers get the job done.
They don’t touch the rear passenger seats, despite the name. They adjust the same general area seat slammers do, but in the opposite direction: slammers drop that point down, rear seat jackers raise it, adjustable in quarter-inch increments from 0.25″ to 1.5″.
Install removes the rear seat base bolts, loosens the front bolts, and slides the adjustable spacer under the rear seat legs, torqued to 35 ft-lbs. No cutting required.
Owners commonly install front seat jackers first, then add Jeep Wrangler rear seat jackers afterward to fine-tune the angle further. Rear seat jackers don’t replace the front product, they build on it.
One tradeoff worth knowing: raising the seat too much starts to interfere with your sightline out the front windshield.
4. Seat Extenders: The Legroom Fix
Not every complaint is about the seat’s height or angle. Seat extenders move the entire seat track further back, adding distance between the seat and the pedals and dash, a legroom fix rather than a height fix.
They also raise the seat 0.25″ to 0.375″ as a side effect, not enough to substitute for the height-focused products, but worth knowing before you order.
Misch 4×4’s BigBoy Seat Brackets add 5 inches of legroom. No drilling, about 10 to 15 minutes per seat, sold separately for driver and passenger side.
Diesel, 4xe, and 392 models need a different, dedicated Misch bracket, which adds 6 inches instead of 5.
ExtendMySeat Jeep JL brackets, a different manufacturer, also add 6 inches with no drilling. Both are a Jeep JL seat extender option depending on which fits your trim.
These solve a different complaint than the other three products, knees hitting the dash or steering wheel, not a flat seat bottom or a low roofline.

Frequently Asked Questions
What are Seat Jackers for Jeep JL?
Seat Jackers for Jeep JL are bolt-on aluminum spacers that tilt the front of the seat up for better thigh support. Several companies sell Jeep JL seat risers; Desert Does It’s Fixed and Shorty Front Seat Jackers, sized by inseam rather than one-size-fits-all, are the versions covered here.
A Wrangler JLU front seat lift kit works the same way regardless of door count, since fit is based on the driver’s measurements, not the vehicle.
Are seat jackers and seat slammers the same thing?
No. Seat jackers raise the front of the seat for better thigh support. Seat slammers drop the rear of the seat for more headroom and legroom, mainly for taller drivers. They solve opposite problems, and some owners have installed the wrong one for their actual issue.
Both get grouped loosely under Jeep Wrangler JL seat risers as a category, but a Jeep JL seat riser isn’t one product, it could technically be either of these two doing opposite jobs.
Can you combine seat jackers and seat slammers?
Yes. Desert Does It’s own instructions confirm it: Option 2 of the Seat Slammers kit already includes a pair of 0.75″ Shorty Front Seat Jackers, combining the front lift with the rear drop to reach the full 0.5″–2″ range. It’s a documented combination, not a workaround.
How do I know which seating fix I actually need?
A Jeep JL seat lift is usually the fix for a flat seat, and Desert Does It’s own fit guide is the starting point: a 28 to 38 inch inseam generally points to Seat Jackers, Shorty or Fixed depending on where in that range you fall.
Height over 6’2″, especially combined with hitting your head on the sound bar or roll bar, points toward Seat Slammers instead. If your Front Jackers already feel close but not quite right, Adjustable Rear Seat Jackers fine-tune the angle further.
Jeep Wrangler seat risers front and rear both raise the seat rather than move it back, so a seat riser for Jeep Wrangler owners with a legroom complaint won’t fix it.
If the actual complaint is knees against the dash rather than a flat seat or low headroom, that’s a legroom problem, not a height problem, and a Misch BigBoy or ExtendMySeat bracket addresses that directly instead.
Do seat jackers require cutting the seat?
No. Desert Does It’s Fixed and Shorty Front Seat Jackers bolt to the existing seat rails and factory mounting points. Their Seat Slammers are the one that requires cutting the seat’s rear mounting legs.
Does trim level change which seat jackers I need?
No. A Jeep Wrangler Rubicon front seat lift uses the same Fixed or Shorty sizing as any other trim, Sahara, Sport, or 4xe, since Desert Does It’s fit guide is based on inseam, not trim package.
The Desert Does It Seat Jackers Jeep Wrangler owners install most often are the standard Fixed and Shorty versions covered here.
Is it safe to cut the seat mounting legs for seat slammers?
Desert Does It’s own instructions recommend professional installation, and rate the job 4 out of 5 for difficulty. They also include a specific caution about wires and wire raceways running through the area being modified, and instruct adding a shim if your seat rail rests on wiring.
Seat Jackers carry an FMVSS 207 structural certification, DOT/NHTSA-required, a static test measuring seat anchorage strength, not a crash simulation, though Desert Does It calls it “crash-test certified.” Seat Slammers don’t have an equivalent claim.
Worth noting for balance: the stock seating position itself is a documented complaint among taller owners, independent of any modification, several describe it as uncomfortable at highway length drives. This doesn’t resolve the open question about a cut mount’s crash performance, it just means the comparison isn’t stock-is-automatically-safer, it’s two different sets of tradeoffs.
Wrangler Specs does not recommend or endorse this modification, any decision to proceed is the vehicle owner’s own.
What’s the difference between Shorty and Fixed Front Seat Jackers?
Desert Does It sells two sizes of Jeep JL front seat jackers, Shorty and Fixed. Shorty lifts the front of the seat 0.75 inches, built for a 28 to 34 inch inseam. Fixed lifts it 1.25 inches, built for a 36 to 38 inch inseam. Both install the same way, no cutting.
Do seat jackers actually help with back pain on long drives?
Multiple owners reviewing Desert Does It’s Jackers describe less lower back pain and better thigh support on long drives. Results aren’t universal, some reviews just mention improved leg support day to day without singling out long drives specifically.
Are seat jackers worth the price?
Several owners call Desert Does It’s Seat Jackers one of the best investments they’ve made in the Jeep, especially for daily comfort. Whether it’s worth the price for you comes down to how much your current seating position actually bothers you.
Can I install seat jackers myself?
Desert Does It’s Front Seat Jackers, yes, straightforward DIY work. Their product page says 10 minutes per seat; owner reports for both seats together run closer to 45 minutes, so budget for the longer end.
Seat Slammers are a different category of project, rated 4 out of 5 for install difficulty by the manufacturer itself, which explicitly recommends professional installation, since the rear seat legs get cut and that step isn’t reversible if something goes wrong partway through.
A Jeep JL seat jacker driver side install and a passenger side install are identical in process, just repeated on both seats.
Do seat jackers work with power seats?
Yes, Desert Does It’s Front Seat Jackers and Adjustable Rear Seat Jackers both list compatibility with manual or power seats.
Their Seat Slammers also now work on 2024+ power seats, though the install has one extra step not needed on manual seats: drilling out a rivet that holds the power seat’s threaded rod in place.
Confirm your exact trim before ordering.
Sequenced right, seat jackers, seat slammers, rear seat jackers, or seat extenders can fix your seating complaint. Confirm your inseam, height, and door count before ordering, that’s how you make your purchase correctly in this category.
Curious what else is confirmed for the JL platform beyond seating fixes? You’ll find sound and audio brands, seat cover manufacturers, and other Wrangler accessories interior categories on the Wrangler Specs Parts Directory.
Seat slammers especially is a significant install project, not a bolt-on afternoon, since it requires cutting into the factory seat mount. If you’d rather have a shop handle it, you’ll find Jeep JL install shops by region on the Wrangler Specs Builder Directory.
