This page at http://www.shockwarehouse.com/site/bilstein_5125.cfm lists collapsed and extended lengths and maybe provides a few more options if you measure you compression and full droop lengths. Of course, it seems to me it makes most sense to just measure full compression length and get the longest one that will fit, maximizing extension. Seems like all the recommendations from earlier in the thread recommend 255/70 valving.

Per part numbers above, ordered the 5100 units for front. Truck has 0 lift, and upon install i had to compress these a couple of inches.
Does that seem right?

I don't think blistein realizes that the early to 73' fj40 rear shocks are about 3" shorter than the 74" and up fj40s. There part numbers don't reflect that anyway.

Which comment? If you are asking which shocks to buy, your very best bet is to flex your suspension without shocks and measure both the compressed distance and extended distance. Second best would be to measure your static eye to eye distance and order a shock where that distance falls right in the middle of the compressed and extended length. You can use the shock warehouse link above to see the compressed and extended length of the shocks. With all the variables of different suspensions, both sagging stock springs and aftermarket lift springs, the only way to get a shock that works for you is to measure.

The comment directly above the comment I posted ;) Stating that the 73's and earlier may have 3" shorter struts than the later models.

Ok, I think I am a victim of this. Ordered the shocks listed for my stock non-lifted 1970. I had to compress the rear quite a bit. I see the fronts listed are 4 inches shorter. I will order another front set And use for the rear.

Those boots look just like mine - crappy at best . I can't believe Bilstein , given the expense/quality of the shocks have the worst boots ever...

Sarge, you saying that shock is appropriate for my application and not compressed too much? I was going to get a shorter one...
