Racing shocks have resistance on the extension as compared to the typical shock that has resistance on the compression.

Here's what I'm talking about.

Huh? Shocks -- racing or not -- have resistance in both directions. Below is a chart of Tokico drag shocks. This chart is typical of every shock that I have ever seen -- more rebound than compression.



Compare with a road racing shock:



No difference (note that the compression/rebound is flipped between them).

Normal passenger car shocks are also similar.

I notice that is a STRUT, is that with the spring installed?
I'm using a SHOCK, not a strut.
I can compress it with one hand VERY EASILY! (regardless whick setting)
I can barely extend it using both hands and my feet (screwdriver through the bottom hole and I'm standing on it) when it is on the higher settings.

That's my point -- every shock I've seen has more resistance to rebound than to compression, but they all have resistance in both directions.

What seems like no resistance in your hands can be considerable when the shock is forced to move hundreds of times quicker than your hands can move it. Think of squeezing syrup -- you can damn near empty a bottle with no effort at all if you take your time. But try to empty that bottle in one second and the resistance is impossible. That is what the graphs are showing.

One reason why you can compress it easier is because teh SPRING is offering some resistance were as on rebound the spring is HELPING to extend it. So the majority of the shocks are going to FEEL like they dampen less in compression.and yes there are exceptions to the rule.But I know guys with acr vipers that run almost no dampening on the compression and almost full dampening on rebound for this reason above.Look at the rates of an acr car they are OVER 1200 on the REAR springs and their shocks cost over 2k EACH.STan

Guys with the QA-1's you order, it depends on what your height of your truck sits at like everyone is saying. A lot people lower their trucks so the part# listed from QA-1 probably isn't the best selection to get.
