Looked to me like a little wheel hop. You may have bounced off the bump stop and unloaded the rear suspension a little. Are your rear shocks adjustable? Are they set to soft, medium, or firm? If they are easy to adjust, I think you typically adjust the rear to as firm as possible so it "shocks" the tire and works better. Front, depends on your goal. If you need a little weight transfer to assist in traction, soften them up a bit. Don't soften enough that when you launch, the rear is slamming into the bump stop though. That can unsettle everything and then you get wheel spin or wheel hop.

@randeez or @iamdub may be more inclined to help resolve that than I am. I've never messed with and suspension on these trucks, other than basic replacements.

All the shocks have 18way adjustable compression and rebound setting and I had them set to the 600hp or less drag racing setting which I will have to look at the chart to see what that is. I don’t think it hit the bumps because it has several inches of up travel but anything is possible.

the best way to learn, is to have everyone laugh at you the whole time

first gear on the nv4500 is stupid low right? probably going to hurt you the most trying to go 10' and making an immediate shift

People laugh at me all the time anyway cause what dumb a$$ would try to make a 3ton brick go fast with a transmission from a dump truck.

Yes, first gear is low (5.61-1) but the 3.42s and 33"s help it some, I can do about 30mph in first if I push it over 6,500 but I seem to short shift out of first a lot. I do think Second is gonna be the fastest just because of the time it takes to shift and the fact second gear is basically the same as the first gear in a 4l60 (3.06 in the 4l60 and 3.04 in the nv where the 80E is 2.48)

@pwtr02ss did you notice the bit of axle movement on the video where it spun really bad in 1st?

Any idea what my weak point in rear axle stability would be? Or maybe it was just good ole G80 funky monkey stuff?

In the 16.5 3k launch vid, watch the 19 second mark repeatedly. I saw very little weight transfer. Traction broke from the shock of the clutch dump before anything could get moving. You're gonna have to get the shocks set better and find that sweet spot between dumping and slipping. Then, after you roast the clutch and glaze the flywheel, you'll have to re-learn all over again with the new performance clutch.

I thought the same thing even in the moment I never felt that squat back feeling. Guess I need a bunch of street practice and shock trial and error. I do have 2 spare clutches in the shelf one of which is fairly aggressive but I really don’t think the clutch is in any danger they are massive

I hate selling stuff used, I posted a very detailed post about the LTZ20s and Nitto 420s and had well over 30 people message about them. I have 10pics in the main ad and took another dozen upon request before a guy came and bought them. I met him, and left him alone to look at the tires while I finished up something at work since he came to my work to check them out. He asked me all sorts of questions and has a cool truck he was gonna put them on. We agreed on $500 I helped him load them and he went in his way.

An hour later after he got home he noticed there are two plugs in one tire and another has a minor dented lip on the inside of the wheel. I did not specifically count the plugs and post that in the ad nor did I zoom in on the dent and point it out. However they balance perfectly and hold air forever I never have to air them up.

Anyway he’s acting like he wants his money back and should be compensated for his time because I was untruthful and he had to drive an hour one way to get there. I feel like he had his chance to look at them and of course there are minor flaws with a set of ten year old wheels and 3 year old tires. He should maybe try them out and see they are fine and brighten his outlook on life.

It's such a quick and hard shock that you see the fenders and hood rattle. Misdirected/wasted energy.

Yas. Hence "Test-and-Tune" days at the track!

If this was how it worked, then fast food/other crappy restaurants, dollar stores, Harbor Freight, etc. would be out of business for paying us to drive to their locations to purchase something which we later decided was unsatisfactory.

It's "Buyer beware/items sold as-is, where-is/no warranties, expressed or implied".

Dang I didn’t notice the hood and fenders until you said that!
Yeah already half planning a trip back but gonna focus tuning efforts on buddies Denali. Doesn’t mean I can’t do shock tuning tho!
