I don't have the power level that you guys do yet. But I do get TQ steer when launching in 4Hi. It's only there for a moment then everything is smooth again. I am only getting 1.98-2.0 60's right now so I KNOW it will get much worse when the 150shot goes on.

Thx for the tips.

what big tex is saying could be true but it seems to me most lowered vehicles loose weight transfer so i figured by droping it i was loosing weight transfer. either way you look at it droping helps a ton. i do still get some tq steer sometimes and sometimes it just launches straiht, depend of the road. I never let anyone start a race standing in the middle of the road anymore, it is just too unpredictable and will only get worse.

here is a video of a prety wild launch http://www.neufamily.org/truckvideos/crazylarge.mpg that was after the drop, i get almost that much wheel spin now and sometimes it is wild like that but other than the steering corection it is an ok launch. when i had the bucking it was way worse. tex had a video of the bucking somewhere, it was prety funny but bad on parts.

It looks like a combo of front traction and rear spring wrap. the rear springs wrap and if you didn't have a 4wd would wheel hop but as the wheel starts to hop the front pulls the truck forward and allows the wheel to snap the truck forward causing the bucking motion. My burb will torque steer launching in 4wd but it doesn't hop around. traction bars or a four-link would plant the rear. also what a the I think they are called the tru-trac diffs they are a type of gearless locking diff. they require some traction to lock but it would allow better torque balance to the front wheels. the lowering probably does limit rear weight tranfer and allows the front to pull better.

I was going to say the same thing. If it were a 2wd, it would have bad wheel hop.

Yeah Jim, it was funny.
