100HP 4X4 Power Wheels Get's Long Travel Suspension and Off Road Tires! + FULL SEND!

[Applause] [Music] so today's the day that colonel senders becomes even more awesome because we're going gonna give it long travel suspension widen the a-arms and most importantly put on these beefy knobby tires so we have real traction and better handling the steering on this thing has always been absolutely terrible it has a ridiculously wide scrub radius the scrub radius is the distance between the point where this steering pivot meets the ground and the center of your tire but you want to set a scrub radius that's essentially fairly close to zero this isn't even close to that so part of that problem is these spacers which we'll be able to do away with with the new wheels and tires these have three inches of offset from this surface to this surface these have five so that gets the center of the tire much closer to this pivot point and the easiest way to imagine why that's a problem is just if you try to grab this part of the steering here and turn it it takes a fair bit of effort but if you would imagine putting a lever way out here it'd be way easier to turn just like putting a larger wrench on a bolt well that's essentially what happens when you have a huge scrub radius is that the tire now has drastically more leverage over your steering system that also means it'd be less stable because it's narrower which is why we're going for extended a-arms as well [Applause] [Music] basically i'm just going to replicate this a arm uh but make it three inches longer so i've got this spot here um that's three inches farther out uh but the shock mount and the um sway bar mount will stay in the same place relative to these ends [Applause] [Music] me [Music] this video is sponsored by cove we love this split speaker we've been using it in the garage for over a year and it gets crazy loud [Music] and this is my favorite part right here you basically get two for the price of one surround sound in the garage one upstairs one downstairs the range is awesome the speaker can normally run for up to seven hours and it's a great father's day present so head on over to cove audio dot com slash gp73 to get 67 off this awesome speaker that's covadio.com gp73 gp73 at checkout will get you a huge discount but for now let's get back to building well that's one rear lower a arm more or less done i still have a little bit of beefing up to do with these brackets but i think that's sturdy i went for overkill um because well many reasons one uh we want it to be beefy uh two it's three inches longer so there's more leverage on everything and also uh it's smaller thinner while tubing than the original was so it needs to be beefier in other ways and then build another one and then another one and another one and another one and another one got eight of these things to build it's gonna take a minute no but i started with the back ones because uh the lower rear is because of the most [Music] complicated the upper rear control arm took drastically less time to uh rebuild i basically just cut out the middle bits and replaced them with longer ones or these two these two arms so i i used reused the end here and both of the pivots of course it was around seven inches of travel before maybe seven and a half something like that uh now it's ten so we gained like i don't know 40 percent more travel or something like that it's a lot i took all the preload out of the shot and it still comes up quite a bit more [Music] operation colonel sender's long travel is uh continuing obviously i got the one side of the rear done and so now i'm mirror image copying it for the other side which will go a lot faster because i already know exactly what i'm doing and i already have all these brackets and stuff marked out on this sheet of 11 gauge steel here so yeah finish this one today do the upper then the rear will be done aside from paint and then uh then the fronts which will also be a lot easier because they're all straight lines i mean there's plenty of bracketry and reinforcement needed for the shock but there's no big hoopy loopy things like this [Music] before i start in on the front control arms i'm going to go ahead and sandblast and paint the rears so that they have some time to dry and you know look nice and pretty [Music] got the rears all done and painted now it's time to do the fronts um this is the front upper and it's the more complicated of them so i'm gonna start with that [Music] here we've got the original front upper a arm you know uh pretty basic here we've got the new front upper a arm which is super duper overkill beef in comparison uh also obviously three inches longer because that's the whole point of this endeavor and it's definitely way stronger than necessary [Music] we'll see what happens with the other side uh because it has the engine case might be in the way but on this side we now have 12 inches of potential travel here so we had this rubber bump stop in there before um and also before the tires would hit the fenders so that was essentially the bump stops well now the tires are outside of the fender and with the longer a arms and these beefy shocks we've got from there all the way down to there [Music] [Applause] [Music] [Applause] basically the final step to long travel is longer axles um i couldn't find any for sale so uh we're gonna make them longer so the plan here is just cut it in half and then make a sleeve that covers the whole thing for maximum strength you know the sleeve will be three inches longer than what's here and then it'll um you know weld it back together and hope for the best [Music] [Applause] [Music] [Music] well got my uh extension sleeve done um you can see i've got little holes drilled in it so i can weld directly to the shaft through those and obviously right now i'm getting it nice and hot so that the uh expands a little bit and then the axle should just slip right in there with minimal persuasion i was supposed to go in there and it's still got an inch to go morning workout well that's axl number one extended and welded and uh ready to go back in we've got the new control arm here on the bottom already um because i was testing some other stuff but uh yeah time to see if it all works together the way it should well that's uh this side assembled aside from the spring and of course the tire but uh there's our 10 inches of travel i have a plan for the springs because these are the springs that were on here these shocks are out of a yamaha rx1 snowmobile and with the previous amount of travel these springs were too soft we had the preload absolutely maxed out and it was still on the soft side that was good but like barely hard enough so what i have here is one of the original shocks from a kawasaki brute force 750 that we stole this um suspension stuff from and uh obviously the shock is terrible in comparison so we're not going to use the shock but i cut one apart and pulled the spring off and it is quite a bit longer so more preload adjustment and it's also a slightly stiffer spring rate so with our added travel and leverage that should be just about perfect so just gotta clean it up paint it orange and then slap it on there so [Applause] [Music] so so exciting times the front axles took way less time to extend because i happen to have a piece of relatively thick wall tubing that fit it perfectly so i just cut it you know cut them and then slid them into this and you know did the little four little weld spots and then welded the ends what that means is the center of three inches is just hollow so it's not as strong but it's the front which doesn't take as much abuse as the back because it's not always being driven it should be plenty strong time to put it back together and find out [Music] i'm rigging up my uh specialized ghetto spring compressors here um we have real spring compressors but first of all they're made for much larger springs and second of all they scratch all the shiny orange paint off the springs so what i've got here is two chunks of cheap nylon rope so you stick your straight piece of whatever in this case a punch in there you twist it around and uh try not to scratch the paint off of everything and look at that hardly any damage to the paint on the shocks i'd say that's a win-win [Music] time to see if it was all worth it huh oh yeah it was worth it even already i haven't even driven it i know it's worth it but yeah this is the uh the moment of truth [Music] to do a jump that huge for the first one shows a lot of confidence that was awesome man [Music] um um [Music] [Music] [Music] it must feel pretty good holy cow wow uh yeah it's not even related to this machine it was you know how the steering was always like barely manageable yeah now like i keep thinking something's broken it's so easy to steer you can't even tell you're trying like it feels like you're not moving anything like i hit a big root and a stump and i literally like i was trying to feel it in the steering wheel i couldn't and just like just steering at any speed i haven't tried four wheel drive yet that was all two-wheel drive but uh also the traction increase is big and the suspension you just that one jump i bottomed out and dug frame into their landing it has so much travel dirt sane and that was like your second jump too yeah so it must feel pretty confident oh it's so good it's and i mean the travel the rear is stiffer than i would like i as i suspected the rear's on the stiff side and you can feel how much travel it has like when you get on the brakes or even just let off you can just feel it dive to the front or like lean to the rear when you get on the on the throttle man it's a totally different machine did you see the first time i came around i just mobbed off of this and landed like down here on the flat yeah no problem i think the front needs to be a tad stiffer on the suspension and the rear needs to be softer so we're gonna have to figure out something other than these springs like i'm glad that it sucked so bad to begin with because that meant we put the power steering in which means that now it's just buttery smooth [Music] [Music] man it's really amazing what proper steering geometry can well that was the most fun 10 minutes of riding in this thing i've ever had and now it's over because one of my axle extensions surprise surprise uh sheared in half so that needs to be beefed up but once we beef up that we're gonna do another full send video because it's so much better than it ever was before it's a whole new beast and for that it deserves a better place for full sending so we're going to go to a very exciting place that's like actually a professional off-road race track and you know all the good stuff hill climbs rock gardens jumps yeah so that's going to be epic as soon as we uh get a stronger solution for these axles [Music] [Music] [Music] you
