Default 4wd launches

For those of you doing 4wd launches how are you building your front ends, I know I need HD tie rods same as my 09 2500hd diesel but how are you bracing your center link to keep from bending it?

I am looking at building my 03 2500hd to 500-600hp and racing it at the drag strip, and need to figure out what parts I need for the front end.

1000+rwhp with 100+ full power launches on drag radials.

stock front axle, stock cv shafts, and stock transfer case.

Keep the cvs level and youll be fine.

Ok thanks, I guess with the lower torque it is not a problem on the stock front end.

Weight is the biggest thing. The 1500s will spin the fronts before you break something.

Less on a gas engine than a diesel, as you pointed out, diesels make twice the torque and are a couple hundred pounds heavier on the front axle, so much much harder on those parts.

The 2500hd front end parts are bigger than the 1500, so that will probably balance out the extra weight.

No , if the angles are not flat tie rods AND center links WILL be broken / bent , true story .

On my old CCSB Dmax with 530 Rwhp tune , 8-900ish tq , I had green torsion keys to level truck, Cognito braces , tie rod sleeves , did 3 4x4 launches , broke tie rods every time , and bent the big *** center link .

Got rid of those damn green leveling keys, I then put on a tough country 6" lift , and with bigger 35 14.50 tires , I NEVER broke anything again when doing a 4x4 launch .

Flat CV angles are the key to not breaking front end parts , 1500 or 2500hd .

My silverado has stock tie rods , no sleeves and I have been launching for 4 years no prob no broken parts . Works for me .

On a 2500hd I would do the Fabtech upgraded inner and outer tie rods and the Cognito idler and pitman arm brace.

AND FLAT ANGLES!!
