I have a 2006 Viper, I get severe wheel hop upon hard acceleration. The tires I have are Nitto Invos. How can I eliminate the wheel hop?

Better suspention is one way. Gives more controll. That wheel hop will lead to destroyed spider gears in the diff.

Stiffer motor and tranny mounts is the first step to getting getting rid of wheel hop. then unfortunately only more expensive adjustable shocks will help get rid of the rest

Driving technique also. Once you over power the tires grip. .... It can lead to wheel hop.

Take off hard-axle wrap up, You think dodge would have taken care of this, My 06 from a roll has this, My 340 duster will launch, not as fast as the viper, but it has no axle wrap[as we call it] I had someone tell me my Viper sounded like a box full of bolts when I launch,

All good suggestions above :)

Also if you happen to still be running the run flat tires they have always been the worst at creating wheel hop.

There is no "axle wrap" on an independent rear axle setup. The differential is locked into position, bolted directly to the frame. Axle wrap occurs when leaf springs flex during a hard launch, then the leaf springs unload.

On an independent rear axle vehicle, there are different reasons for wheel hop. Sometimes it is just due to harmonics between the two half shafts. On many vehicles, the manufacturers have learned that using two different diameter half shafts help cancel out the harmonics that cause wheel hop. Tire traction, shock settings, spring rate, alignment, even surface/pavement can all affect wheel hop. Here are some simple things to try:

Lower the tire pressure to 25-28 psi.
Don't take off too hard in 1st, learn to throttle it.
Stiffer spring rates in the rear usually help.
Stiffer shock settings in the rear usually help.
Stickier tires definitely help.

But, no matter what you do, NEVER try to ride out wheel hop. That is how the rearends break on IRS cars. Never ever ever stay in the throttle if the rear wheels are hopping. Lift off the throttle immediately. I've ran my '06 coupe (1,000+ rwhp) very hard and have never broken a stock rear axle. I know better to lift when hop starts.

Nine ball-thanks for your reply, sometimes I think faster than I type, what causes the wheel hop on a stock SRT? Knowing the diff. is firmly bolted to the frame, the wheels still ,Load ., unload causing hop
If I am going 10mph and nail it, it hops,and bangs, of course my leaf spring duster does not do it, just spins until it hooks, It has to be in the rear suspension on the Viper?Any comments?

Control arm and differential bushings are another major contributor. Difflection in the OE rubber can "wrap" just like old leaf springs, creating a cycle of alignment geometry change and tire loading in an IRS car. The way our differentials are mounted solidly at the pinion leads to the control arm bushings being a much bigger contributor.

I will say the biggest thing is drive throttle input. It doesn't matter how solid of a suspension setup you have. Poor traction from the road and tires. Smashing the gas will cause wheel hop in the "right" conditions.

I blew up my rear diff due to wheel hop. Got rid of wheel hop 99% by using polyurethane engine/transmission mounts. I had Nitto Invos as well.

Red---I ******* about the same problem forever. I changed my rims/tires..I changed to a complete kw adjustable suspension ..changed
Transmission mount.....and still get wheel hop from time to time. I've learned to drive accordingly ...like from a roll nail It at 20-25 not 10...not saying u cant nail it...but if you start to feel hop you better left off

Sure, keep nailing it at 10mph, and getting wheel hop.

Learn to roll into the throttle a bit. You aren't going to be faster when you are spinning/hopping/overpowering the tires.

That's just my suggestion. You do understand you have pretty much 400+ ft/lbs of torque as soon as you nail it right?

If you DO want to just nail it, get better tires, like the NT05R drag radial. That will help it hook better and reduce wheel hop. If you plan to stick with your INVOs then you might need to adjust your driving habits.

BTW. When I picked up my Paxton 03, it had some regular tires on it and on 2nd gear punches, you can feel the rear hop a little as it's spinning. Switched to the NT05R DRs and wheel hop is pretty much eliminated and I can hook EASILY from nailing it in 1st gear. The only hop I get from time to time is if it's spinning just slightly in 1st I grab 2nd, it might hop a tad going into second and then the hop goes away. I pretty much just ease it into 2nd now.

Has anyone used offset shaft weights?
CTS-v, Camaro etc use this setup to address wheelhop.
Be interested if anyone here has done it and if its helped?

higher spring rates cure the "HOP" 95% of the time, increasing the rear 425 lbs to 800's keeps the tire on the ground.

Good old Achims Razor, the simplest solution is usually the right one, don't over think it, just fix it.

Will the stock Konis on the gen 2's be able to handle linear 800 lbs. springs by adjusting them?
