Default Air shocks and Air bumps

When using Air shocks do I need to run bump stops? Being that the design of both are similar and the spring rate for both become exponential near full compression. Do I need both???

I have air shocks and just some rubber bumps cause I would rather have it bottom out on the bumps vers the shock tubes

Probably a 2 part answer. I don't think you need them if you are not racing .... and .... your shocks are properly tuned. You have it right, they are self damping when reaching full compression. I never bottom mine out (see disclaimer below) and I've hit the whoops at Silver Lake way harder than I should. But, it's all in the tuning and air pressure. I have 12" shocks and run about 5" exposed rod at the dunes. When hitting things hard, if you look at the seal wipe on the rod, I usually stop about 3/4 - 1" from full bottom. On the other hand, I run about 3 1/2" exposed when rock crawling. If I hit some high speed stuff in that condition, yes, I have bottomed out a couple times.

So, the second half of the answer is yes, you need them if you are never going to change your air pressure and risk compromising them... or if you are going to race.

You can avoid bottoming out the shocks by setting your bump stops so the bottom out 1/2 inch before you're shocks do
