A good parts store will have books showing the length and mounting style of shocks.

In the Samurai boards, they jack up one side so it is on the bumpstops and the other side is at full droop (shocks removed) they measure each side to find extended & compressed shock length. IIRC they call it "ditching the truck"


Will post link if I can find one

"We see this a lot....

"Which shocks for my set-up?"

While it is true a lot of our rigs are similar, the truth is each induvidual build is different unless done by a mass produced kit. Even then there are still differences. Therefore, what works for one rig may not be the best for a similarly built rig.

So how do we find the correct length? Easy, measure for shock travel.

1-Max out the flex on the axle. Stretch one side out, stuff the other ....both as much as possible.
This can be done several ways. A forklift, ditch, flex ramp (duh!) or a small, loud Japanese car, lowered w/ a nose kit on it. I wouldn't try a jack...they could move on you.

2-Measure between the shock mounts. The actual mounting locations. Either center of stud or bolt hole. This is how the shock companies do it. Measure both sides....the extension and compression will give the needed shock travel.

3- Add at last a half and inch to the extension....and add half an inch from compression.
This keeps the shock form acting as the bumpstop.

4- Go to your favorite parts store. Ask the guy at the counter for the shock book. They ALL have one....or more. If they won't let you....find another store.

5- Look up your stock application and take note of the mounting points (shock ends).

6- Match up the shock ends w/ the travel you need. You may have to give a little here and there.

7- Repeat steps 1-6 for the other axle if needed.

8-You're done!....GO WHEEL!


This works for any rig......even circle track racecars.
This should work for and grade of shock.....Ranchos to Red Ryders.
