Midengine Suspension

[corndog2]

Hello,

I'm a newbie building a midengine rail. The frame type is similar to
the Hi-Jumper Sprites (no torsion bar at all), with a swing axel tranny.
I'd like to get some reccomendations regarding shocks for this
type of rail. I have read through lots of the posts on coil-over versus torsions options,
but havent seen anything specific to these types of
frames. Obvioulsy I have to go for a shock,
but I see a lot of variation in price. Cheapies up to super expensive.
Can you get away with a cheap coilover ? The Hi-jumper site seems to
push the Nitrogen Billet shocks for these rails, is that a better
way to go than a coilover ?

Comments welcome.

thanks

mabee take a look at fox air shocks. they are nitro pressured. but they are rated at #900 a corner. i am shure thats more then enough for your mid-runner. the only down side is you need a nitro tank to adjust then. i have been priceing them out and i think it will be around $150 bucks for the tank,reg,hose,pressure,gauge

[FreakingGomer]

with the air shocks, you run no torsions, only the air shicks, and no coils is that correct? I hear them mentioned from time to time but cannot seem to wrap my mind around them.

I've had Fox nitrogen shocks on my sand drag buggy for years, pricey but a great shock.
Marvin Shaw is another nitrogen shock for your application.
Less expensive are coil over Carreras.

I have a sprite my self and run a bilstein with a coil over kit. I have had no problems with the set up.

right gomer. fox makes two kinds of air shocks smooth body (non coil over) and treaded body (coil over) here is a pic of my air shocks that are coil over air shocks. you probubly would not need coils on yours. i have the on mine because i am setting mine up to jump. but you rail will probubly be light enough for just the air shocks.
call chris at oregon motor sports and he will hook you up

all the mid engine cars ive seen have those midengine buggy shocks i forgot what their called but their on the back of this car

it looks a little messed up because it is, my friend turned to look behind to see if his mom was following and went off of a 5 foot drop off and went end over end 3 times, and this was right after we had just replaced the nose cone to........


wait i take that back i just found em!

you can get a set of fox for about the same price and imho they are a way better shock. with way more travel potential.

I thought his travel would be limited by the swing axle trans he's running not the shock?

tuff puff where did you get the adjustable link for your limit straps?

soldier, those are the adjustable clevises that are available from moores or pacific customs, about $28 each plus $5 handling fee plus an outrageous shipping fee.....

i couldn't find anything like them at the john deere place...

This has been very helpful.
I have a much better idea of what folks are using.
I have some decisions to make.
Its been great to see the pics of these buggies(even if they have gone end over end...ouch).

I'm sure I'll have more question soon...
Just want to get this frame rolling at this time.

I found a pic of my Fox shocks.
They are pretty old but have never leaked off any.
Have had these on for ar least 15 years.
These and the wishbone trailing arms are the whole suspension of this car.
Straight liner only though...............

You can see the shock at the left tire, the rod is pretty massive, about an 1-1/4" or so in diameter.

when somebody says air shocks, i think of those old gabriel hi-jackers or what turboblue has on his buggy.

tuff puffs shocks are what i would call a nitrogen charged shock with a dual rate coil-over kit on them. i wouldn't call them an air shock.....

i think the original question was about air shocks......

baja. they are a "air shock" they use nitro cuz it has no moisture in it. there for no corosion. "nitro charged" still use oil to slow them down. the nitro is just to keep the oil from makeing froth. also it harder to find a air pump to go to #250psi like i am running in mine now i think they go up to like #350-#400psi but that would be awful stiff. also i have seen long travel rails. (a-arm 20" type) that use just air shocks front and rear. no springs no torsion bars. just shocks.
runslikeapenguin. there are LOTS of mid engine rails that are "long travel" infact mid engines jump WAY better then rear engines. for the most part. cuz they are so balanced.
my clevis ends i got from oregon motor sports. (503) 251-2925 in portland i think there like $25 ea. i little pricey but it make adjustment sooooooo easy! just drill a hole weld a tube. done!

[Skidmark]

The nitrogen is used mainly due to it not expanding with heat like air does. Road racers use it in their tires as well since they can limit the amount of pressure build up when the tires heat up. Tire pressure is critical to gain maximum traction. Yes, the pressure is to keep the oil from foaming.
