Huffy Torex mods.

Sorry if it’s off topic but this is like the only thread that shows up on a Huffy Torex google search. Unfortunately it’s not about batteries but a few mods I’ve done to my son’s to make it “better”

First were the springs, I replaced the 650# stock springs with lighter springs off mcmaster carr. These allowed the suspension to actually work. Install was simple, the black thingy in the e strut tube unthreads and the unit comes apart, simply replace the springs.

Second was the controller. I didn’t plan to replace it but after a bunch of kids piled on a ride it to death, the stock controller got cooked. I contacted Huffy for a new one which was a waste of time. So I searched and found a unit that works. Model YK31 500w with reverse, eBay special, about $50. I got it with optional throttle pedal for variable throttle. The kit took some trial and error. I can go over wiring if anyone needs details, but in a nut shell, I only wired the rear wheels. The motor plug on controller needs swapped, simple, and reverse the polarity as that time. The “brake” harness is a false hope. This was most of the trial and error. Since these Torex’s sorts freewheel the brake needs to function. I tried the “brake” harness, no effect. I then noticed if it was in reverse it would “brake” so I wired the brake to the reverse input. Needless to say it wasn’t ideal and eventually burned out that controller. So I got a new one and started retesting. I discovered a better option. I repinned the brake pedal to normally open. Was easy. Take the switch in pedal apart, move the pin to opposite side, put back together. Then I wired that inline to the power switch, negative side. So now when he brakes, it turns off the power to motors and they then “brakes”. We have tested this a good bit and still functions good.

Last but not least, I wired two 12v pc fans in series to the controller, “battery voltage” plug and put them over the controller. This has drastically helped keep controller cool and seems to have increased it’s reliability and performance.

Awesome upgrades! Thanks for providing a link as well.

Thanks so much for posting this. I got my son the Torex UTV back in June and unfortunately it stopped working in July. Huffy sent me a replacement pedal but that did not fix my issue (it only went in reverse) and they said I needed a new controller but they are on back order. I have been looking for other fixes for the controller and this is the only forum I can find on this UTV. I’ve done some research and there really isn’t many options comparable to this ride-on. It’s a solid build but between the pedal and the controller, I’m stuck. I will research more about this controller you posted and again, thanks for the info!

The Torex pedal is a 3 wire and would be compatible with YK31 and may even be variable, haven’t confirmed though. The variable throttle is very nice to have

I found this forum from a google search. Since last Christmas I have replaced the controller 3 times and each time is a month long wait from huffy. Can you send or post some detailed instructions and pictures on how you did this? I hate to junk the utv because my son loves riding it so if this fixes it that would be great.

I just got on vacation, so I’ll need a week. It’s a YK31 controller off eBay. The stock pedal is infact variable and will work. You just need to repin some wire which is pretty simple. I found the front tires only spin about half as fast as the rears. I guess it’s for pulling out and then they just freewheel at speed when rears take over. I did a lot of trial and error getting wires right and the brake to function properly without burning out controller.

Well I contacted Huffy on 9/23 and they sent me another controller module. Unfortunately it worked for maybe a week and went to go use it today and it only goes in reverse again. I contacted Huffy again so we will see. I’ve only had it since June. Has anyone else had success with the YK31 controller module or any other fix? I should’ve got the warranty to just return it. It’s a shame because I haven’t seen any other ride-on for younger kids that’s reliable that goes as fast or built as strong as the Torex UTV

Have you looked into li-poly vehicle batteries?

There are a a lot of cautionary reviews on YouTube, apparently it’s possible to make them quite profitable by skipping important steps in building them.
(I looked around a while back for some home fire/earthquake/emergency home power storage batteries to upgrade from my collection of old 12v car batteries, but didn’t find something that sounded reliable.

But there might be something out there. They’re much lighter weight than lead-acid batteries, too.

That’s what keeps happening to ours. The new controller will work for a few weeks and then it dies. I’m hoping this controller is promising.

The battery doesn’t seem to be a problem, it last long enough. If I needed more range I would swap in 3 nissan leaf batteries cells for 24v. With lithium batteries you need to be careful draining them. Something like a buzzer that warns you at 10% to stop and charge.

Here my 4 yr old on his with yk31 controller and softer springs

Sorry I’m too lazy to write it up but I filmed it.

Thank you as well for posting the springs. I ordered some shocks from Amazon but were over $130, they are probably still too heavy, and won’t get here for a month. I ordered these springs as well, thank you.

Wouldn’t it seem logical there is some other issue causing it to die? Maybe the ridiculously hard suspension (half-joking). Ours has been fine too but a) I live in a cold climate b) it’s not used for more than 10 minutes at a time.

Not sure if any of those factors are saving me, but had good luck so far.

Mine died after 4 kids hung on it. It’s abused but with my kids and their cousins all playing together, it’s inevitable.

Ps I have a brand new unused controller huffy sent me through warranty. It took almost 3 months to get it. I’ll send it to someone that needs it for shipping cost

So a little update…I had to contact Huffy again about my second controller module issue. I got a great rep who sent me another controller, second battery as well as a bridge connector to hook up both batteries. I was very appreciative that they did that but they did tell me they cannot keep replacing the controller since I’ve had two others go out. Time will tell but I think the issue here is the controller and I honestly don’t know if there will be a fix. Having two batteries will be great for a longer drive time but I fear that will just put more stress on the controller. I haven’t had any other issues with the UTV and my son absolutely loves it so fingers crossed!

This is my first post in this forum. I have a chance to get a display of the Torex UTV. Huffy has recommended I make this a custom project. With a YK31 controller, what other drivetrain components and batteries are recommended? Apparently the displays are shipped with no wiring and no drive components so this is my chance to make a much improved Torex UTV. TIA

12V 16Ah Deep Cycle LiFePO4 Battery, 2000 Cycles Miady LFP16AH Rechargeable Battery.

Would 2 of these (thinking one in each compartment since they are slightly bigger) work far better than the factory 7ah batteries. It is true that 7ah to 15ah is just be longer-lasting power? I should not hurt anything with these? At $50 apiece, it seems two of these LiFePO4 Batteries make more sense than trying 4 cheaper batteries.

Looking for advice from the electrical specialist that has been on this string. Thanks!

I’m no “electrical specialist”, but I bit the bullet to try two of the lifePo4 12v 18ah from Dakota lithium. These are the biggest batteries that will fit in the 2 slots allotted on the Torex. I also bought the 24v charger since the SLA charger is not compatible with LifePo4.

While this is an expensive upgrade, I found these batteries to have good reviews and a quality built in BMS that won’t allow for overcharging or over-discharging. They are also supposed to be safer than Lithium Ion. LifePo4 do not catch fire according to what I have read.

The only wiring I had to do was put 2 connectors on a 14awg wire to connect the batteries in series for 24v. Then, I removed casing from OEM battery and used the existing wiring harness/fuse for the LifePo4’s. This was a direct swap with no parts needed. However, I use the gator clips on the Dakota 24v charger by clipping them on the opposite battery poles that were used for the existing harness.

So far, so good. There is no comparison to the run time from the SLA battery that came with the machine. The top speed does not degrade as the battery loses power. I don’t know exactly how long they will go, but it has been driven at least 1 hour of constant run time today and is still checking in at 26.1V.

I’ve only had the Dakotas in for a few hours, so I’ll have to report back once we have a month or 2 on them and give an update.

Hope this helps.
