Will Schocks stiffen my ride?

Question

I have a 91 gmc jimmy s15 4d 4whd, and i just put 33in tires on it and i think that the schocks are so old my car is starting to sag, i was wondering if i bought new schocks it would lift it, because these schocks cannnot hold the weight of my car any more. So if i bought new one would it lift my car at all?

Answer 1

Shocks do not fix sags. Coil springs in the front and new leaf springs in the rear fix it properly . Air shocks will not do this job well at all. Shock mounts are not positioned properly or heavy enough to carry loads. Shocks reduse movement of the road and spring energy in your trucks suspension..

Answer 2

Shocks do NOT provide any lift what so ever.

Vehicles suspension
In a vehicle, it reduces the effect of traveling over rough ground, leading to improved ride quality. Without shock absorbers, the vehicle would have a bouncing ride, as energy is stored in the spring and then released to the vehicle, possibly exceeding the allowed range of suspension movement. Control of excessive suspension movement without shock absorption requires stiffer (higher rate) springs, which would in turn give a harsh ride. Shock absorbers allow the use of soft (lower rate) springs while controlling the rate of suspension movement in response to bumps. They also, along with hysteresis in the tire itself, damp the motion of the unsprung weight up and down on the springiness of the tire. Since the tire is not as soft as the springs, effective wheel bounce damping may require stiffer shocks than would be ideal for the vehicle motion alone.

Spring-based shock absorbers commonly use coil springs or leaf springs, though torsion bars can be used in torsional shocks as well. Ideal springs alone, however, are not shock absorbers as springs only store and do not dissipate or absorb energy. Vehicles typically employ both springs or torsion bars as well as hydraulic shock absorbers. In this combination, "shock absorber" is reserved specifically for the hydraulic piston that absorbs and dissipates vibration.

Answer 3

The Wiki answer above is just saying this--your springs are most likely gone. You should replace the springs and the shocks with such big wheels on the truck now.
Shocks do not support the car, they dampen the springs so you don't oscillate after hitting a bump.

Answer 4

A simple explanation...The shock absorber does just that. It helps absorb road shock that could result in a loss of control. The springs or struts on a vehicle are what actually support the weight, not the shock absorber. You may be confusing the terms shocks and struts. They are two completely different items.
