Measuring for Shocks 6" lift Long Arms, these the right size?

[ARareBreed]

I'm measuring for shock length for my 5.5-6" lifted Comanche. I used an engine hoist to lift off the front tire. I'm interested in the Fox 2.0 shocks, the part numbers I think will work are below.

 

My Measurements:

Front Compressed 20.75"

Front Ride Height 23.75"

Front Extended 27"

 

Rear Compressed 19.75"

Rear Ride height 22.75"

Rear Extended 23.75"

 

 

Front

985-24-132

Extended 29.55" - Collapsed 18.45" - Stroke 11.1"

 

Rear

980-24-644

Extended 28.85" - Collapsed 17.75" - Stroke 11.1"

 

The compressed and extended dimensions will fit fine, I'm worried about ride height since I do not know the shock body length, is that something I should be worried about?

 

Let me know what yall think!

Is your lift completed? If so, measure the distance "at rest" between the the upper/lower shock studs (rear) and the lower shock stud to the upper fender mounting point. I'm assuming you are using the stock shock mounting.

That's what the ride height measurement is in my original post.

Then I'd say UB fine using those shocks.  :thumbsup:

...how are you achieving the extended and compressed length measurements?  you say you used an engine hoist to "lift off the front tire".  please explain.  are there any shocks currently bolted on?

 

really the most effective way to is to measure mount-to-mount length at ride height, then measure how much distance your bumpstops are away from the contact patch.  look for a shock that is about 2" less than that bumpstop measurement.  example, ride height length is 23".  distance between bumpstop and contact patch is 4".  get a shock that has a collapsed length of 17"

I can't upload pictures on posts, but that's exactly what I did. I tied a tow strap to an engine hoist on one of my wheel spokes and lifted the front tire until the rear tire was lifting off the ground. I did this without any shocks and front sway bar links disconnected.

 

I follow your logic though, that should be easy to do. Thanks.

But were your bumpstops in contact with the corresponding par5ts of the suspension? If the bumpstops weren't making contact, you didn't measure full compression.
