Suspension Seat recommendations

Postby Rusape » Wed Sep 27, 2017 10:21 am

Guys, my truck obviously has no suspension seats, so I am looking to replace the fixed seats with suspension type.

I've searched but there seems to be very little information about. I appreciate that this is a subjective topic, but can anyone advise on the best type of suspension seat for these types of vehicles... if indeed suspension is the way to go.

TIA

Again your truck is a bit different Lazz, most of us have incredibly crude leaf springs and bargain-basement military shocks.

The most popular retro-fit is KAB mechanical seats as these perform well, are adjustable, are reliable, last well, are easy to maintain, do not rely on air, are comfortable, are comparatively cheap and are amongst the most compact.

KAB 411s and 414s seem popular. Ours have been bang on.

Agreed Steve

Our seats are also mechanical and the rebound is full adjustable. They tilt in every direction and have arm rests. They are also heated .

Ours are made by ISRI ( Isringhausen ) and are similar to the KAB seats, we looked at both but these came up first

Question then guys.

Why not air seats? The whole truck relies on its air system, which I assume is fairly robust.
Are the air seats a common failure, or are the mechanical more comfortable.?

I've not used either before, but thought air was the way to go...no?

I think the ride is similar .

I had no real preference , it was just what came along at the time .

However, I would say that when the pressure is down ( maybe after a few days parked up ) the seats will drop down to a low position. They will only rise to the driving position once the air pressure is up to max. They should be connected to the axillary air circuit which is always the last to pressure up.

I don't think they take much air so I wouldn't think you need extra tanks to accommodate them .

Its horses for courses but I have sat in both and the ride is the same

Every day is a school day...

Thanks Neil, I'll try both before I make a decision.

Just to add that cost was a factor for me but more important was avoiding unnecessary complexity. Mechanical seats fit well with the simplicity / reliability ethos of overlanding trucks.

Air seats can and do present with reliability problems with truck and tractor drivers sometimes reporting they can develop a mind of their own and pull tricks like fully inflating and refusing to yield; so leaving the driver with a difficult and potentially dangerous driving position. Even if this kind of thing is rare - and I don't doubt it is - it doesn't make sense to me to introduce the possibility. Enough can - and will - go wrong anyway.

Just my take; not saying air seats are clown shoes...

There is a similar thread running here that might help

My truck came with an Isringhausen air seat. I have never used a mechancial suspension seat so have nothing to compare it to, but the ISRI seat is remarkably comfortable. It is easy to adjust and smoothes out the ride very well.

It does very little to make washboard roads more comfortable, and can make delicate thottle control awkward on very bumpy roads.

The only change that I would make, would be for a slightly more padded supportive seat.
