It went all the way to the bump stops so there wasn't much movement

 

To bump this back up, im very happy with how my truck is launching now with my coilovers in the front and assassin bars in the back. No limit straps. Have the rear shocks as firm as they will go and the fronts I think 15/18. You dont want the suspension to move at all, but you dont want it to bottom out either. Lots of preload on the traction bars set the most aggressively (bottom hole in back bracket, top hole in front bracket)

275 drag radials on all 4, roughly 15psi launch ramping up to 22ish. It breaks a little when full boost hits but keeps going forward. This was on an unprepped street btw, on a track it should stick like glue!

 

love the ladder rack!

 

In leiu of adjustable shocks and coilovers, I should have ok luck strapping the front end down and cranking my CalTracs as tight as possible correct?

When cranking up the traction bars, I see how that can reduce rear end squat, which should keep more weight from transferring from the front to the rear, but doesn't it also put more of the rotational force from the rear axle onto the frame, which would act to lift the front end? Does the reduction in squat more than offset this additional lifting force?

 

Yea you should, but you have to make sure you preload it so it wont move much. The ride sucks like this btw.

It does stress the frame more, but thats ok. The adjustable coilovers really help in the front by adjusting them so the expansion is highly damped.

 

Yeah I was thinking just for the track, definitely wouldn't drive it that way. I may do coilovers at some point, built trans and lift pump are coming first though.

 

Sounds like a marketing scam to me

 

I forgot the real term for it, but the shock rebound rate thing

 

I leave mine in 4wd till I let off the go fast pedal, sometimes 140mph+
no issues, just don't turn.

 

Hey guys. I'm new here and have a question.

I have a 2014 GMC Sierra crew cab 4x4 with the 6.2.

Currently all stock and plan only to do a custom tune, muffler and drop in air filter.

Can I launch it full throttle and run a 1/4 mile straight line in 4 hi without expecting any damage?

And can I launch in 4 hi and then turn he **** back to 2wd after the shift into 2nd.

I get a lot of different answers depending on who I ask
Thanks,

Jim
