Introduction: Knex Suspension Pickup Truck **Suspension Upgrade/Mod #1**

Picture of Knex Suspension Pickup Truck **Suspension Upgrade/Mod #1**
I built this with a version of suspension I made a couple months ago. The range is great. It is pretty strong and it doesn't look out of place like some other versions of suspension. In the future I would like to build a version that can steer and maybe even move with some form of motor. Any ideas?

Step 1: Suspension

OLD VERSION -Follow the steps to make each individual suspension unit. Your will have to repeat the steps 4 times. In total your will have 2 of the piece in this picture. One for the front and one for the rear.

NEW VERSION- Go to step 9 and make 4 of these units. Connect 2 units together with white rods. This will give you a front and rear suspension unit.

Step 2: Front Chasis

This should be pretty easy to build.

Step 3: Rear Chasis

completing the rear chasis

Step 4: Some Assembly

Putting the front and rear chasis together. Add the wheels.

Step 5: Hood, Grill, Headlights, and Bumper

Assemble the components that will make the truck look good.

Step 6: Side Panels

The side panels need to be made. Meke one for each side. Add the doors with a simple snap.

Step 7: Roof

Pretty easy.

Step 8: Final Assembly!

Now for the fun part. I think you should be able to see how each component is added. I ran low on battery in my camera so I tried to conserve the power by taking as few pictures as I thought I needed. I have modified my own truck since I built this one. It is now a six wheeled box truck with massive suspension and a rubber band powered opening back door. Why? I really don't know.

Step 9: Suspension Mod #1

This suspension is a lot less fragile than the previous version. It requires NO Y connectors and no further modification to the truck. It requires only a few spacers to be moved. The rubber bands are also much easier to get to meaning it is easier to adjust.

your truck looks brilliant! ima build it once im done building my rifle....

ThatGuyRandy (author)2011-08-29

I've used this on a k'nex atv, and it worked great. What I did do though, was switch the yellow connectors that the wheels connect to for white ones for to increase the height, although this requires 2 of the 'spokes' to be cut off to allow the suspension to move.

this would be even more amazing if it had larger tires, that said it is still amazing as it stands
(haha, i just realized how late this comment is)

cool i used to really be in to knexing but havent really done it in a while bu i think ill try this when i get some free time

knex365 (author)2011-09-25

I've designed a spring suspension the same size as this, I might be posting instructions. But I've also made a brilliant trailer that should fit this, so I will definatly post some instructions for that!

gunner1089 (author)knex3652011-09-25

I would like to see both. I will take a look when you post them.

knex365 (author)gunner10892011-12-20

I've complete the trailer instructable here's the link! (

This is very good. maybe check out my monstertruck with suspension.

JBomBer94 (author)2011-10-04

pretty simple A arms up front, you can put them at any length you want..the only defect about longs arms like these is they tend to bend back when pressure is applied to them at a certain can kind of see a gray long rod on the buggy leading from the rear arm mount up to the front A arm as it help ALOT by keeping it in place and not bending back..the trophy truck front arms dont really need it as they have alot more hot glue on them and are sturdier.

so is the supension prety strong

Tomas48 (author)2011-07-26

I just made this step 9 suspension mod for my truck that i made and it works GREAT really good design.I put my 3 1/2 inch tires on it that i ordered my and it still works very good. i have a motor on the back of the truck but im gonna try to figure out how to make it have a motor and suspension as well...Any Tips on how to put suspension and a motor on it? Please reply(:

gunner1089 (author)Tomas482011-07-26

I wish I had some ideas for the motor/suspension but I have had no luck. I have tried everything I could think of. I think there may just no be a way for it to work at this scale. The best way would be to have some sort of drive axle but I don't know how that would work. You could try rubberbands/chain to make a pulley type system but it would not look good. I am really out of ideas. If you can think of something that works, please post it. Good luck!

iWeeksy (author)gunner10892011-08-14

I've used your suspension and put steering on it :))

choctapus (author)2011-07-08

i ran out of those single grey pieces   :)

slimshaddy (author)2011-03-20

what if you dont have the right size tires can i use other ones that are slightly smaller?

gunner1089 (author)slimshaddy2011-03-20

It should work but it might look a bit funny.

slimshaddy (author)gunner10892011-03-20

k just wondering

gunner1089 (author)2010-12-28

I think I was checking the tire pressure of my car one day when I took a look at the suspension. I decided to try to convert the real suspension to a knex version. I tried many times but couldn't really get anything that was strong or reasonably sized. I had the eureka moment when I snapped the grey and yellow connectors together in that interesting way. Once I had that I knew I could many small but realistic independent suspension. If only I could come up with such an innovation to allow for steering.

superbestknex (author)2010-11-17

do you know where to get the knex gray motors

gunner1089 (author)superbestknex2010-11-17

I not sure what motor you are talking about but I wouldn't know where to buy it anyways. I haven't bought any knex in years.

superbestknex (author)gunner10892010-11-19

The ones knex discontinued they spin at 200

Rawrrr (author)2010-11-18

i modded mine, it now has 6 wheels, please check it out

superbestknex (author)2010-11-14

so how long did it take you to build

i think you did a great job which suspension works better the one on step one or the one on step 9

gunner1089 (author)superbestknex2010-11-15

Honestly I don't remember. The step one version was the original but it uses quite few y-connectors. Some people complained that there were too many y-connectors so I made the Step nine version as an alternative. I don't remember if one was stronger than the other but I know they both work similarly well. The step nine version has rubber bands that are easier to change.

gunner1089 (author)superbestknex2010-11-14

It took me a while to figure out how to make the suspension initially. Once I knew how to build it, it took only a couple of hours. If I wanted to build it fast it could be build in under an hour. For anyone trying to make it from the instructions, it will usually take a couple hours.

superbestknex (author)2010-11-14

Thnx i looked on ebay and they were on it

superbestknex (author)2010-11-14

cool truck but where do you get those tires

gunner1089 (author)superbestknex2010-11-14

Those tires were the standard tires years ago. I got them back around the year 2000. I don't know if they still make them anymore. I haven't bought a new knex kit in at least 7 years.

20p (author)2010-06-04

aaaaaaaaaarrrrrrrrrrrrgggggggggghhhhhhhhhhh got no rubber bands

smattman22 (author)2010-03-19

What did I tell you about leaving your bananas out on the floor!? ;)

knex_ninja (author)2010-01-05

Try putting one of those green motors on the front wheels... just a pretty basic idea, I haven't built the model.

gunner1089 (author)knex_ninja2010-01-05

 what motor is that. I don't have one but is it small enough to fit within the suspension?

sizzam960 (author)gunner10892010-03-03

i do not think you can have suspension in the front if you put a motor on.

thinkfast999 (author)2010-02-28

Nvm  I got it!! works sooooooooooooooooooooooooooooooooooooooo good

thinkfast999 (author)2010-02-28

how do i put the wheels on?

KnexFreek (author)2010-01-22

 COOOOOOOOOL!!!!!  stars!!!!

lukas rider (author)2009-12-06

i like your truck ,but i made it 4wd by puting 2 motors.

gunner1089 (author)lukas rider2009-12-06

 Nice, could you post some pictures? I have never been able to get motors to work. You have two motors and you still have the suspension. I would like to see how you accomplished that. Thanks

lukas rider (author)gunner10892009-12-11

it does not have any suspension.u r the only nice person on instructables i have meet. and i wrecked that truck.u should look at my stuff i make on instructables.

gunner1089 (author)lukas rider2009-12-11

 You have a good start. Just keep working come up with some cool ideas to build. I keep looking at your stuff but when you do post your first instructable, let me know. Thanks for the comment.

lukas rider (author)gunner10892009-12-12

your welcome . I might do an Instructables by January . but I need to think of some thing cool to do. 

sunnybacon (author)2009-08-07

Hey dude, I built this just now, it's awesome! This is the first model I've built since buying my K'nex recently, and it's so good. My little bro loves playing with it :P Good job on the design and everything :)

smattman22 (author)sunnybacon2009-11-30

build my mods for the truck! they rule

Lowney (author)sunnybacon2009-09-24


tommytomtom (author)2009-07-13

heey ist me again doe you have the tank ready or not ?? if you can't build it it not a problem but if you can please post it im waiting

gunner1089 (author)tommytomtom2009-07-14

hey, i am sorry for taking so long. I tried to build a tank but i can't get the body to look good. Also, I can't get the tracks to function correctly. Using grey connectors and white rods looks good but my motor wheels just slip. Using the regular black chain functions well but looks terrible. I just got frustrated with trying to build it. I can still show the suspension. I can't tell you exactly when I will have it posted but I think it should be up this weekend. This time I will post something. sorry about last time.

tommytomtom (author)gunner10892009-08-17

k thx i have the same problem with the grey and white but ist ok if you want to post thx XD
