    Default 2500 Springs and Bars on a 1500

    Has anyone tried this?

    Mainly, I want the stance, but I'd also like to have the ability for the extra load capacity.

    Also, are there any diffrences between the 2500 and the 2500 HD Springs and Bars?

    It seems like one of our Silverado members here has 2500HD torsion bars on their 1500.

    it may work, but it could really hurt the ride if you are gonna put it on the Z71 it may have that air ride and would check into that as to how they set that, having the heavy springs and bars could really confuse the computer

    I have the 2500HD springs under the back of my 1500 4WD. It actually raised the rear end about 1.5-2 inches, and did increase my load capability (pulling a car hauler, with no noticeable squatting). The ride didn't really change, but I didnt have the air ride, nor did I do the front torsion bars. My truck also has been lifted 6", so the ride was a little rougher than stock to begin with...

    The rear springs were pretty easy, but we have a lift at my dad's, so that made the job easier.

    Anyways, The hardest part for me was finding the springs. The rest was relatively easy.

    I'm really not worried about ride quality, as the ride now is pretty weak, and could stand being stiffened up.

    I need to know if there is a diffrence in torsion bars, other then the index keys. If the bars are the same through the different trucks, then all I should need is the keys from an HD and I'd be set.

    Can anyone confirm if my last statement holds truethfull?

    Also, there is no Air Ride on my Truck.

    Default torsion bars

    I was just reading a post on a different site about torsion bars. Check it out.
    My '03 2500 LD ext cab Z85 has the "K" bars. Another thread on that site indicated that the dealer lists the bars by torque rating. In any case you can look at the ones you have and bump them up a step or two if you want a heavier spring.
    The 1500 keys are indexed differently than the 2500/3500 keys. Some guys are using 1500 keys on the heavy trucks to raise them, which indicates that if you put the 2500 keys on a 1500 it would lower the truck. This info pertains to the '03-06 style trucks, not sure how it relates to the older ones.
