cool, just an opinion but you could always notch the frame rails over the front axle. All that work on the 4 link seems like you wouldnt get full use of it. Very nice though!!
you need to double sheer your link mounts, just having them bolt to one tab is not going to be enough, they will bend for sure, so you need to have a tab on both ends of the bolts that hold your links in place, better safe than sorry.
the suspention looks awesome but in my opinion there is way to little suspention travel!! if this is built for a rock crawler then there should be a lot more travel in the suspention due to the fact of the chassis and axles flexing and on and around obsticles... but great job though!!!
@lucasmorter Harbor freight Piece-of-shits, but they are affordable (as in less then $20 each). "Real" shocks you find on, say, a Polaris Razr or several hundreds of dollars and way out of my price range for what I am trying to do.
the coilovers appear to have a good percentage of travel left, its the lower frame rails. You could run 180 degree hoops in the lower rails you obviously have a bender. Or just some angled uprights and small cross member to give it a notch and keep strength. Regardless of your weight when that vehicle is cruising around and hitting inclines aka jumps that axle will smack the rails. And keeping the shocks at an angle will give you more travel and help to keep your axle centered with short links.

Awsome fab work. You can't buy that anywhare! I am building a go kart for my kids too. I wanted some bind-free flex for off roading. I built a front suspension like a sprint car. I used those same shocks more horizontal, got 6" of straight travel and about 14" of flex without the sway bar, and about 10" with the sway bar. my sway bar runs parrallel with the steering arm to minimize bump steer. I wish I had seen this video befor I started. I would have used a four-link design too.
@sneaky5sniper I could space it out more, but really there is not that much weight in the front to compress the springs as much as me jumping up and down on it. Thanks for watching.
Everything was going so well until I saw the metal crashing together when you stood on the frame. I'd go with tougher shocks and use rubber bumpers between the possible points of frame contact.
@cocotower That was a bit deceiveing. You see, I am around 210 Lbs and I was jumping up and down to show the suspension movement. There is not going to be nearly 200 pounds of weight at the front when this thing is done, so it will never make contact under normal circumstances. I could mount the shocks in more of a vertical angle to create more resistance to weight and to give more ground clearance, but I don't think it will be neccessary. Thanks for the comments!
@cocotower Got ya. Well, I was thinking that if the kart is going fast enough and hit a mound or pot hole, this might create 200+ pounds of upward pressure. I was just guessing, though.
i've often pondered building an offroad suspension very similar,, theoretically that thing should just GLIDE over bumps at high speeds,, and it will absorb more impact from bumps from the rearward swinging pendulum motion of the front axle.. very nice work,, how were the results?
this is a pritty cool build ... I was thinking of doing something like this also but got distracted by something else ... now after seeing yours its inspiring me to do mine
Yes, but then the front end would be higher than the back of the cart. Right now, the frame is level and I wanted to keep it that way. I'll eventually go to a double wishbone front end at some point in time. And an IRS in the rear using VW bug axles.
Overkill?? Yes. More of a proof of concept than anything else. The existing riding lawnmower that I scavenged all the other parts from had a straight axle on the front so I figured a 4 link would be cool.
Nope, not going to happen. First of all, NO ATV stores carry ATV shocks in inventory. So, I can't determine how long they would be. Second, they are WAY too stiff for the go kart I am building. I can pick up the entire front of end of the go kart with one hand. No one can do that with an ATV. Nice thought though. Thanks.
@hardtimesx2 the springs are rated to hold about 250 lbs each but there is hardly any weight at all on the front of the cart, so by mounting them at an angle, you essentially decrease the spring rate due to the force vector. Plus, they just fit better like that.
Well, my problem is that the only shocks I could find (at Northern Tool) only have about 3" of travel. With my four link I would like to have had about 5 or 6 inches of travel, but I can't find shocks like that. Bike shocks are very short travel (an inch or 1.5") but use levers to acheive 5 inches of travel. I didn't want to complicate the design with levers and such. Maybe the next go kart!
well i guess id have to see it in motion as a finished product to really know eh. i never even thought to make a front end suspension like thatbut i like it. i probaly would have gone with A- arms or something. other peoples designs give me ideas tho, its cool
you need like a loop aboce that axle or something so it won't bottom out like that

how does the steering wheel connect? when the suspension is fully depressed doesnt that pust the steering wheel up?

or you can weld another tube on there lower than the one you have the shocks mounted on then mount the shocks on the lower one
