Default Golf Cart Build

Decided to ditch the ATV this year and picked up a golf cart in its place. All internals seem to be stock and overall the cart looks good.

Since I canít leave well enough alone Iíve decided to start upgrading! Iíll be documenting my build here as I go along.

On 23Ē tires the cart tops out at about 19mph.

Wanting more power Iíve decided to add a 400amp alltrax controller, Admiral A2 10hp motor, and HD solenoid.

Started by trying to remove the rear of the cart, but that quickly seemed like a lot of work! After doing some reading, decided to drop the rear axle and get to the motor that way while waiting for the controller to show up.

While under the cart I noticed the rear springs didnít look like they had much life in them so decided to pull them off. While there I took a look at the shocks, they could be compressed with one finger!

Iíve been tossing around the idea of a 4 link setup in the rear, but for now Iím going with HD springs.

Nice, may have to bounce some ideas off you as I go along.

Motor and controller just got here. Will be waiting on the springs to get it installed.

You'll love that controller & motor setup. I took an already semi-built cart and did the same thing you are doing. Going in I had minimal knowledge of DC electricity and had a ton of fun with the build. What I figured out in the end as far, as power is concerned, is that no matter how many electrical upgrades I did my biggest limiting factor was always going to be weight (rolling resistance), which you can't avoid unless you have lithium batteries (do-able, but expensive). I had a heavy duty steel winch bumper that I didn't really need and my "clays basket" was also heavy duty steel.

Here are my suggested upgrades:
  • 2g cable set for battery & motor. Add digital volt meter so you don't run your lead acid batteries down below 70% S.O.C.
  • HD reversing contactor solenoid - done
  • Alltrax controller - done
  • I fed 42 volts to a 36v motor and got much more torque and top speed
  • 8 ply tires - I didn't do this but I highly suggest it. Doesn't take much time for a golf cart tire to go completely flat.
  • Red led light strips in the cubby holes & floor boards (golf carts aren't made to drive at night ). This is the cheapest and most functional upgrade I did.
  • Red LED light pods for driving around the farm at night. Enter SUPER STEALTH MODE!! Crazy how many critters you'll see in an electric cart with red lights at night. If you want a white LED bar, you can find some on amazon that have a voltage range of like 12v-72v so you can hook it straight up to your battery pack and get way more power out of it, and won't have to add extra weight of an extra 12v auxiliary battery.
    * If you hunt/drive in the woods, take the top off. It doesn't provide that much shade, nor provide much protection from the rain and I promise you it will catch every.single.dang.limb.

The other upgrade I wanted to do but never did due to price is add disc brakes.

Nice list!

Actually have a few of those things Iíll be adding for sure!


Hint: depending on budget, one MAY be lighter batteries sometime next year...

Should be getting mid 20s with the motor/controller setup. On the ranch rarely ever did more than 10-15 on my ATV, so thatíll be plenty of speed.

Got the new HD springs installed, HUGE difference from the worn out stock springs. Much better ride! Donít think Iíll be doing the 4 link for link unless itís horrible off-road.

Now, for the motor... put the cart in reverse to roll it out of the garage ... the tires squeeled! wasnít ready for that much torque!! Definitely have to get used to the new throttle inputs. Gained about 9mph top speed as well, win win! Canít complain.

I have the HD springs on my cart and it rides like a chuck wagon on my rocky hill country lease. Im thinking building another cart to keep there with a 4 link and long travel. Have you seen any 4 link kits for carts all I've seen are home made.

Actually thought really hard about a 4 link and Iíve been in touch with someone whoís done it.

Itís really not that hard and would run around $400-$500 depending on which shocks you go with.

Parts list:


Hereís his setup with air shocks and 4 link.

I may have to consider that motor upgrade. My cart has plenty of torque with a 10hp motor and 700 amp controller but 15mph tops on a good day.

Canít imagine the cart having more torque than what it has, as it have to ease in to the throttle to avoid the front coming off the ground. The speed is nice around the neighborhood, but doubt Iíll use it on the ranch... unless I upgrade to the 4 link!

The A2 is not considered admirals torque motor, itís supposed to be a balance of torque and speed. Their torque motor is the A4, which I was really debating on buying for $100 more. The A2 is more than enough for my needs for sure.

What controller do you have? Are you running 1ga cables with that setup?

I know someone whoís running this same 400a controller and and motor with a lithium setup get mid 30s with a range of 60+ miles.
