i have a 1981 camaro i put longer shackles on the the back that are 4 inches longer. the distance between the two shack mounts is 20.75. what should i do about shocks? iv looked around on summit and jegs and could find shocks that have an extended length of 22.5 is that enough

 

Whay not keep the shocks you have and use shock extensions? I've made them for cars often, but they can also be purchased.

 

the shocks i have are air shocks and they were blown out when i bought it?

 

You need to get under the car with the axle supported on jack stands and measure the static length of the shocks from point to point. If it's less than the 22.5" it will work, but it needs to be a couple inches less to keep from topping out the shocks on rebound. With weight on the axle I'd want no more than 20.5".

 

ok i cant use the shocks i have now because they are completely rotted out how much room for the rebound do i need? what type of shock extension do you recommended?

 

but with all the weight on the car from top mount to bottom mount is 20.75. thanks

 

That's 1.75" less than the long shocks you mentioned, so it should be fine. Remember rebound comes into play after you hit a bump and compress the shocks, so the extra 1.75" you have will be a good safe rebound cushion.

 

Ok good thank you very much. should i put a shock extension in for a lil extra room or should i leave it be?

 

I wouldn't. You don't want to get it so long that it bottoms out and ruins the seals or bends a shaft.

 

ok thank you i appreciate it.
