Seat Requirements?

[rustyp]

Hi
What are the general seat and restraint requirements for installation in a off road car/truck, seat type, mounting requirements, harness, restraint, limit straps etc. so their is no problem passing any of the tech inspections?

Thanks in advance.

General rules for seats are pretty wide open. you can use any seat from a Sparco (non suspended) to a Mastercraft (suspended). 5 point belts are a must. NO Y-strap shoulder belts. My seats are mounted to tubing with 1/8 4130 welded tabs

Here is the combo I run in my class 10 and 1600 cars. Sparco evo 2 with deist 5 point belts. I would highly recommend using a head and neck retraint (ie. Hans/d-cell/R3).

Many people have opinions on what seats to run. If you dont have any experience with race seats, do a search and you will find many threads on the subject.

i'm hoping you already have the cage built .?

And please make sure your harnesses are mounted correctly. I see a lot of vehicles that have the sholder restraints mounted way to low which will actually compress your spine in the event of an accident. No bueno.

Thanks for the replies.

What about limit straps under the suspension seats bottom to limit its travel and keep the shoulder straps tight during a crash they required?

As far as I'm aware there are no rules limiting the seat's suspension travel, there isn't all that much anyway. I believe the only actual rule about seats is that they have to be a fixed back seat, no recliners. A quality seat is one of the best investments you can make on a race truck, lots of guys like the Mastercraft 3gs, I prefers Sparco or Momo non-suspension seats in a race truck, just gotta strap in right, and in a pre-runner for just cruising around nothing beats a nice comfy Beard and an air conditioned Parker Pumper. Make sure you follow all the harness rules and you'll be fine.

and remember they are requiring double d rings on the seat belts. some seat belts dont come with the double d rings so you will have to put them on.

Below is a reply I got from Mastercraft

I wanted to respond to your question in regards to the seat limit straps, Our seats have built in limit straps, I would also like to point out that we manufacture 5 point harnesses with built in springs that are SFI approved that helps keep the belts tight. I you have any other questions please let us know.

Best regards.
