Rear window shocks???

Does anyone know where you can get new shocks for the rear window on a CJ7 hardtop? I have seen some used ones on Ebay, but they are probably no better than what I have. I think Auto Zone sells some, but I don't know if they have any close to the size I need.

If you have old ones that worked then take them to NAPA and match them up. Just do not trash the old ones until your sure the new ones are the correct pressure or strength. Struts with too much pressure can break the mounts in the hardtop. It is a real pain to fix.

what he said, do not throw away your old ones yet.

have you taken them off and poured lube in the vent hole at the bottom, just be sure they are properly lubed.

I do not remember for sure, but i sprayed wd40 or some other type lube on the shaft and try to get lube inside to the spring.

redneck solution: press the lift springs on a bathroom scales and seen how many pounds the scale reads when you compress the spring. this would give you a starting point in looking for new springs.

also you must have the length of the lift spring: compressed and full extention.

Remember: to buy new lift cylinders: you must know required length: compressed, full extention and max lift pounds

to get max lift pounds guess you must devise a way to weigh the lift gate. then divide by 2 as you have 2 lift cylinders.

The original lift gate struts do not have any hydraulic pressure in them. They are simply two tubes with a spring inside.

So what happens to them? Does the spring break or does the compression wear out?

If you can't repair you OEM springs, McMaster-Carr has gas struts available that you can adjust the gas pressure to what is needed in order to lift and close the rear hatch. There is a bleed screw on them that allows gas pressure to escape so they become softer until you have the correct pressure needed to do the job. We use them all the time at my place of business on our bakery equipment. There called: Reducible-Force Gas Springs

If you have a fiberglass hatch DO NOT use the original spring loaded shocks on it. They are too strong and will pull the inserts right out of the fiberglass. The stock hatch was much heavier.

I went out and measured my hard top. Compressed the struts need to be 12.75" and extended about 20" center to center.

Using these dimensions, I found these struts.
