Can you explain this a bit more? Degrees between what? And under what conditions?
if 0 degrees is parallel to the ground. a straight line between the axle and pivot point should be 10-13 degrees while the bike is unloaded. Typically longer swingarms can have more angle than shorter ones. There are many factors that will dictate the exact angle, it will change depending on application and rider preference. This angle has to do with anti-squat, and the front suspension unloading when exiting corners . Here is an article explaining the factors better than I can.

I wouldn't worry about a stock shocks weight rating too much, there are other factors at play such as front/rear weight bias that can affect how stiff or soft a shock feels. That being said, most factory shocks I have come across are too soft except for the lightest of riders. ZRX adjustable shock has adjustable preload/compression/rebound, none of these will be of any help if the proper sag cannot be set. You will need to re-spring the shock if you cannot set sag correctly
$300 for shocks is a drop in the bucket as far as performance shocks go. you can get some OK shocks for that money that will perform fine for average street riding but nothing I would call a performance shock. I think Hagons cost even more than $300 now. Getting a ZRX shock and having it re-sprung and possibly re-valved by Race-Tech is probably one of the cheaper ways to get a shock setup for your application.

Are they adjustable enough to make work?
Thank!

Heavy? Why? Ed

With the preload adjuster welded as I did, its inoperable. But the shocks stock are too long. You might be better off just installing a limiter and leaving the prelosd adjuster alone. You will need to shorten the spring though because you are adding preload by limiting travel.
And yes, I want the bike a touch lower.

Nice, thanks for the quick reply!
You want to install the limiter because it's still too long for your taste with the modified preload adjuster?

Im going to be taking these apart in a few weeks to shorten them a little, but Ill describe whats already been done.
You remove the stock spring prelosd "pin" and use the housing instead. The problem is the inner sleeve is only held in by friction now. I welded the inner sleeve to the outer adjuster ring. The left side shock is spaced out with a couple washers for clearance.
My plan is to install a limiter (like the last pic) to lower it about an inch.

Hello Kidkawie,
I have a 78 KZ1000 LTD on which I've installed a set of ZRX1200 shocks like you did.
I noticed my chain rubbed on the swingarm since doing the swap and I noticed on your post you have pictures that seem to show you modified the top preload adjuster.
The photos are blurry so I'm not sure how you modified them, could you send me pictures?
Thanks!

With the zrx swingarm the suspension will be wider then stock so i. The new shocks had 14mm ID had two bobbins for the swingarm and drilled a larger hole so it fits the upper shock bracket. The new shocks has 14mm bushings so i took a tube who had m10x1.25 inside . I turned off the outer diam from 20mm to 14mm except for 3mm . Now i have a nut that fits perfect in the upper hole on the shock.
Sorry for my english

Just cut them and remove. They don't serve any useful purpose, and rot very quickly. . I changed mine to same KYB rear shocks for the ZRX1100 , they are identical and bolt on, just a bit stiffer, and those rubbers disintegrated in no time...again......I simply removed them and wear the naked nut under them.
