Made mine.

Bike shifter level, shifter cable and sheath, and a cable clamp.

Ran the cable thru the firewall and hooked it into the throttle body like the regular throttle or cruise and mounted the lever in my gear shift...

Total cost was about $13.00

Does it seem to work well on the trails?

I love mine. When your in 4 LO and you hit some rough terrain, instead of mashing the gas and making it even rougher, it's a smooth idle.

I bought all of my hand throttle parts at a bike shop. It's great for trails and hill climbs where there are a lot of bumps and jarring which may cause you to unexpectedly press suddenly on the skinny pedal. I also use my hand throttle to raise my rpms while winching, using my 12v compressor, or while jump starting another vehicle.

Since I have an auto, I actually mounted mine closer to my steering wheel at the 2 o'clock position. Works for me .

Works great. I got the variety that has the 'clicks' for each gear. So one click is used to raise rpms or use on a bumpy stretch of trail. 2 clicks will be for winching or jump starting...

Some prefer the version that releases when you let it off, but finding that type of lever around here was a problem. So I just went with the kind I have now.

Hand throttles are great on the trail. Not just to control your speed more precisely on a really bumpy trail, but also to hold the rpms up like when you're winching or using a belt-driven on-board air compressor.

I liked how mine worked with my previous 5-speed so well that I reinstalled it after doing a conversion to an automatic where it is nearly as useful. I bought my hand throttle as a kit from Rubicon Express because their kit also includes a bracket that mounts to the throttle body that makes installation a lot easier.

Hint... to attach the cable to the throttle linkage, use the same type of plastic snap-on clip that the factory uses for the accelerator pedal cable and the throttle return spring. You can get one by buying a throttle return spring from the dealer for about $1.50 which includes the clip. Cut the spring off and use the clip.

Not trying to hijack, but can someone explain how this works with a 5-speed? It sounds like it works in gear as well as out, but how does that work with the clutch? How is it activated? I'm actually very interested in this as it seems like it is beneficiail on bumpy trails, but am totally ignorant about it's workings. Thanks!

It works in the same fashion as you pressing the gas pedal. If you're in neutral, it will rev up when used. If you're in gear, you'll accelerate.

It is activated by you touching it and moving the lever. The lever is connected to the cable which is run thru the firewall and to the accelerator in the engine bay.

Thanks! So it works with the gas pedal, not necessarily overiding it? Anyone got pictures of the other (engine bay) end of the setup?

It is also NOT a replacement for cruise control. It is intended for situations where you would need to bump up the engine idle speed.

Good point.
I was referring to use on trail where the bumps could lead to bouncy foot and surges on the pedal.

Hmm I might be interested in a hand throttle. I had a hard time keeping a consistent throttle application last time I went out. Shoving my foot against the transmission tunnel helped, but this would be way better. Could you post some pics of the engine side?

Here is the throttle body just below the air tube. One cable is the factory throttle and the other is the hand throttle. If I had cruise it would be more complicated but I don't,

The gray plastic is the part I got from the dealer and which Jerry mentions. The cable sheath is under that air tube and is secured so the inner cable can move in it, just like on a bike.

Does the cable flex enough that it doesn't cause any issues with the regular throttle?

I'd like to do this as well. I've never even seen one in action, but I've driven tractors so I'm used to the whole hand throttle concept.

i like it, but I aint gonna lie, i'd use it as cruise control also. Has anyone tried twist on , push off type?

I googled this pic, its the big dump truck size, they make smaller versions of this style.

I had one on my Jeep for a while...removed it while doing some work and never bothered to reinstall it.

It actually worked well as cruise control provided you kept an eye on your speed because a sudden change in terrain could make you speed up 10mph or so...plus you also had to be aware that in order to slow down, you had to reset the throttle handle back to idle. Since most of my job revolves around me using tractors with similar throttle controls...it was no big deal...though I would not suggest using one in heavy traffic. Clutching will obviously take it out of gear...but it will also rev the engine up with no load.

I bought my kit online for about $30...not as cheap as doing it myself, but that way they provided all my parts and I didn't have to spend my time searching for all the hardware to do it.

No issues at all. The cable is longest when the throttle is at rest, so when the accelerator pedal is pressed it just flexes the hand throttle wire a bit. Not an issue at all.

If I could get video of it in action, I will. Perhaps my son can give the Jeep gas while I film it on my iPhone...

I had a rubicon express hand throttle on my tj when it was a 5 speed. It is so much easier on the rocks when you can have 1 foot on the clutch and 1 foot on the brakes while controlling the throttle with a hand. I have everything needed to install it for $25 shipped if anyone is interested.
