I have to look at what came stock for our trucks. After this snowball effect I'm confused lol. I know suburbans and Van's have sway bars because there top heavy.. on that note why the k1500 suburban dont have rear sway bars blows me.. IF that's true I can only see it because of off road capability. Now 2500 c or k suburbans I would imagine the extra leafs help make it more stiff of a ride not needing the sway bar. IF it didnt come with it. LIke mentioned above. Silverado are not top heavy so I bet gm didnt require then to have em useless a certain combination offered it. Meaning crew cab or something similar. As far as frames idk I always thought they were the same but somebody had pointed out Silverados are different then the suburban because of the 3rd row. Here's my thought. Silverado may have a stronger bed frame support for abuse but not where it tranform to the cab. Any c frame has always been a weak design also known for twisting. That's why all are boxed frame including suburbans nowdays. So say you dukes of hazzard a silverado c1500 I would bet you bend the frame like a u. Bending the cab and the bed together lol... say you dukes of hazzard a c1500 suburban you would probably blow the suspension before you bend the frame and body or bend the front end to the fender bending that part of the frame.. just my thoughts. But kinda makes sense considering the difference among the 2
Decent summary I think - cheers!
What struck me when I got my C2500 was how substantially built the frame is at the front - as if GM made a real effort to control the suspension and steering geometry there under the duress of the loads from the engine weight, then it peters out into flimsy rails running rearwards. By the time you get to the rear it's looking a bit beefier again (especially considering how effectively leaf springs 'spread' the loads). Kind of implies treating both axles as independent, catering for themselves, and loosely connected to each other via the main rails. Which is pretty much how I view an early Lotus Elan - though main rail (singular!) may better describe an Elan's chassis - despite Chapman's BS about how torsionally rigid it was.
