toyota 4 link wheel hop

ive got a 87 Toyota with one ton chevy axles leaf sprung front an 4 link rear im running a 4 cyl with 538s front an rear with 39.5 irocks on propane, this would be the first time ive built a truck like this an took it on some hills an ive got some wheel hop pretty bad when the tires start spinning,what would be a way to fix that?

How much air pressure and what's on the rear. Coil springs, coil overs or air shocks

The back end maybe to light or dont have enough spring rate
To keep the tires planted. Got any pics of the set up?

Are the tires on a 15" wheel? I had the same problem, switched to TSLs then to REDS and the hop went away. That size irok on a 15 has too much soft side wall and it'll wrap up and let go making it feel like wheel hop.

Too much anti-squat will do that as well. Post pics of your link setup.
You can put your numbers in this calculator and see what you're working with:

Just wondering what good anti squat numbers would be for a bouncer?

Most look to have not much.

Put more separation in your frame side links. Good place to start Will lower antisquat

So instead of aiming the link bars at the COG (which would be squat neutral) keeping the bars almost flat is more desirable?

Wouldn't this effect pinion angle during articulation?

that's the way mine are.....about 5 degrees and uppers are parallel with them

I bet a little air pressure will help you out

Lowers flat with frame side vertical separation 1/2 to 3/4 axle side sep is a good start. Looking for AS numbers in the 40-60% range. Close to/over 100 will hop. Tight center limit strap would help that though.

My internet is messing up thats why i havent posted back i can post pics soon ive got two propane tanks in the bed thats it 2.0 air shocks for the rear i was running 30 pounds in the rear because i was driving it on the road i lowered them a bit an it helped a little bit still had wheel hop i think its got alot to do with not having alot of weight back here most of the inside of the bed is tore ot ill try an post some pics an im running iroks on 15x12 with 2 in backspace

Few pics

Looks like the axle is trying to drive under the truck

A side shot on flat ground would be more telling. Seems like a lot of the Toyota link setups I see with 4-5" lift had high AS. Running the links closer to parallel could help but I'd plug your numbers into the 4-link calc just to make sure you know where you are starting, and what you can expect with different changes. No point just moving bars around and hoping you get it right.

More pics

All you need to do is buy shorter shocks, or relocate your shock hoops higher and drop your ride height by 5" or so.

That would probably take care of 90% of the problem.

The rest could most likely be solved with tire pressure and shock tuning

Moving my shock hoops up an closer together was my plan because if i flex to much one way the shock hits the tire i also have to make a limit strap for it.i appreciate the help an ill try an get it its a work in progress for my first build
