I am just getting into trucks for off-roading and looking to buy a Chevy Silverado 2005. The truck looks like it has a steering stabilizer bars but I am not really sure what they are. Can anyone tell me what this is? Thanks!

 

the first pic is the factory torsion bars installed in the lift kit bracket.

the second shot is the lift kit connected to the lower control arms.

a steering stabilizer connects to the steering linkage and looks like a shock absorber.

sway bars control side to side sway and bolt to the lower control arm

nice truck btw
