first of all id like to ask if any of yall could please post how youve made/ routed your limiting strap on the front end to prevent wheel hop...i 4wd launched my truck for the first time with the new gears the other day n im pretty sure my front tire came off the ground from the severe wheel hop...secondly i need a new pitman n idler since mine are so worn, after a launch n stopping my tires were toed in like no other, then aftera few mi. of driving somehow they managed to go back straight? ive got full 1"dom cognito tie rods but cognito doesnt carry HD pitman/idler arms do they make heavy duty ones at all? all i can find is stock replacement ones and the congito brace kits. if anyone could help me out itd be greatly appreciated!

 

The CV axles need to be almost straight for a 4x4 launch or bad things happen. A cranked T bar, or Key lift could be causing the problem.

 

I have ZERO issues launching in 4WD (I stay in 4WD the whole run). Factory lift blocks removed and going another 2" all around in the spring.

 

I have a 3/6 drop and have no issues with 4wd launching? I cut 1.6 and 1.7 60's on street tires with 20" wheels and a 3600 stall, all steering components are stock but in good shape though.

 

x2, You will have problems with tie rods and 4x4 launches with cranked stock or aftermarket leveling keys. Straight CV shafts are a MUST for least chance of breakage.

ex. My Duramax went thru 3 sets of tie rods and a bent centerlink when i had green keys and cranked them , I got rid of that setup and did a 6'' lift which lowered my front diff and gave me straight CV angles again, ZERO issues with 4x4 launches now.



My Z71 has stock keys that are de-cranked all the way, but i still have straight CV angles and i launch 4x4 no prob and stay in 4x4 the whole down the track, ZERO Issues.

The Key as Stock 48 said is STRAIGHT CV SHAFTS !!!!

 

duramax's are a lot harder on front end parts!

 

Damn skippy brotha! Lots more wieght and gobs more TQ than our 1/2 tons!

Im done racing it, sticking to the " lighter" vehicles now haha It likes towing much better.

 

Ive seen two or three Dmax trucks fold up their front end at bandimere, not a pretty sight. Ran mine quite a few times this season, always in 4wd high all the way down and checked the alignment the other day, it was still spot on.

 

Yea they can be at a slight angle but prob is when the front raises up on launch the angle gets worse. A slight negative angle is fine because they will pull up close to level once you launch.

 

Here's a pic of my limiting chains. They work wonders when they're tightened up without slack.
