rock and brick -

thanks for the advice on doing the fronts also. My 18 has a factory front but i added a rear hellwig. Not sure if its worth the change on my front. mines a CAI, Cat Back daily truck.

 

If your happy with it the way it is then fine. a stiffer bar in the front will help that much more.

Now that I have pushed the truck, I have actually been contemplating installing the hotchkiss front bar on mine to see if I can stiffen it a little more in the front. I have actually managed to find some used hotchkis bits and pieces in the wrecking yard of all places...

 

I'm running helwigg front and rear on my 2005 ECSB Z71 and love it.
I did the rear 1st and yeh, a little better, helwigg said the front adds 30% more improvement and I did it and yes, matching up is the ticket.
Helwiggs are solid beasts. OE and Hotchkiss are hollow.

 

Do you know the spring rates of the Helwigg bars you installed Vs. factory???

 

No sir. I didn't see it in any of the literature. One could call them I guess.
