Hey Guys,

Steve here from Desert Does It, as discussed in THIS thread, there's been an outcry from the Big and Tall JL/JLU/JT drivers. We've been going back and forth on a few designs that will allow you to drop the rear of the Driver or Passenger Seat. This is still a work in progress but I wanted to reach out to the forum for feedback and to gauge interest.

A few things to get out of the way up front:
  • This is not an easily reversible mod (would require welding)
  • Requires cutting of the rear seat legs
  • Each of the below kits will come with multiple "shims" to allow the rear to be adjusted in .25" increments.
  • Each of the below kits will come with a Cut & Drill Fixture to insure the cut and the holes are in the correct place (seats are expensive to mess up).
  • If these are deal breakers, you can check out our front Fixed Seat Jackers and Adjustable Seat Jackers.

Primary Parts in OPTION 1:
  • Cutting/Drilling Fixture
  • Seat Slammer Brackets
  • Two .5" Shims
  • Four .25" Shims
  • Associated Class 10.9/12.9 Hardware

OPTION 1 Drop Combos:
-Drop Combo 1A - No shims in front would require 1" of shims in back (1" total rear drop). Seat Bottom Angle is 16.5 Degrees (factory is 11.5 degrees)​
-Drop Combo 1B - .25" shim used in front would allow only .5" or .75" of rear shims to dial in comfort (1.25" or 1.5" total rear drop). Seat Bottom Angle is 18 Degrees (factory is 11.5 degrees)​


Primary Parts in OPTION 2:
  • Everything from Option 1 plus .75" Front Seat Jackers
OPTION 2 Drop Combos (MAX DROP):
-Drop Combo 2A - Front Seat Jacker (.75") no shims in back (2" total rear drop). Seat Bottom Angle is 22.5 Degrees (factory is 11.5 degrees)​
-Drop Combo 2B - Front Seat Jacker (.75") variable rear shims to dial in rear drop (1" to 2" total rear drop)​

Option 1 is the most economical with Option 2 having the most adjustability.


Looking forward to your feedback and I will add pictures tomorrow.

Thanks,
Steve

I think this looks real nice and clean. With the seat back being lowered, and the angle being different, will this cause legs to fall asleep? I would assume this would put more pressure behind your knees?

Hard to say. We've heard a lot of complaints from people that feel the seats are too flat. That's why we measured the angle at stock and for the different options. We had a few guys of varying heights sit in Option 3 and we all agreed it was very comfortable ( 5'7", 6'1" and 6'5" w/37" inseam). Granted that's sitting on a driveway and not driving it for 8+ hours straight.

Hope that helps.

Hey Guys,

  • This is an irreversible mod
  • Requires cutting of the rear seat legs

  • Each of the below kits will come with a Cut & Drill Fixture to insure the cut and the holes are in the correct place (seats are expensive to mess up).
  • If these are deal breakers, you can check out our front Fixed Seat Jackers and Adjustable Seat Jackers.


Option 1 - 1" Drop
  • Front of the seat stays put and the rear of the seat will drop by .5" to 1"
  • Seat Bottom Angle is 16.5 Degrees (factory is 11.5 degrees)

Option 2 - 1.5" Drop
  • Front of the seat is raised by .25" and rear of the seat is dropped by 1" to 1.5"
  • Seat Bottom Angle is 18 Degrees (factory is 11.5 degrees)

Option 3 - 2" Drop
  • Front of the seat is raised by .75" and rear of the seat is dropped by 1.5" to 2"
  • Seat Bottom Angle is 22.5 Degrees (factory is 11.5 degrees)

Pricing is still TBD but it will be less than $200 per seat but we are aiming for $160 or less.

With all that being said, the big question for us is Steel or 7075 Aluminum. Each seat rail block will have two M10 1.5" Class 10.9 Bolts that mount it to the seat rail.

Looking forward to your feedback and I will add pictures tomorrow.

Thanks,
Steve

Seriously though option 3 please!!!

I don’t give a damn if it’s Aluminum or Steel as long as it’s 1 solid piece the stock seat rails will bend WAYYYYYYY before either of those will.

... now one more time for good measure...

I hate how flat the seat is stock. This will be soooooo much more comfortable!

This looks very promising! Thank you very much for your efforts! My main priority is to increase the distance between my head and the roof. With option two and three it appears as though you're raising the front and dropping the rear at the same time which would tilt the seat, but what does that do for overall dropping the seat so I have increased headroom? Is the overall effect lowering the seat?

Also, the one inch drop( or any of the options). Is that measured at the rear of the seat rail? Or is that what I would approximately gain in headroom?

Is there a way to make an all inclusive kit? Something like buy option 3, but be able to add spacers to raise it if that angle is too much? Get spacers to make it like option 2 or 1

Yes being 6’2” but I agree with the above comments. It would be nice though in being able to have all the options in one kit.

A Benjamin Franklin seems fair. Where should I send the money now? 😅

I was thinking to make this part based on MJHuber post

This could be done for much cheaper but I like the idea of a single billet piece far better than a welded one. Also there’s a good amount of fab skills in cutting and grinding the ones above from his post. His were not roughly cut and ground, they were very precisely done. Probably far above the skill level of most of us.
