If you move the lower shock mount or not, a longer arm will have more leverage unless you move the upper mount as well.



Im not 100% sure but if you relocate the shock mounts on the rear 2" it will make it harder to compress the arm.its the lever thing now if the angle of the shock compensates for the mounts being moved you may be right. this is a question for scooby?

 

Think of it this way, a shock or any other support device will always have the most strength at a 90 degree angle to the load.

Now, I do not know the math to do it right, but moving the mount to the rear does put it at a better location for leverage, but I'm not sure its enough to make up for the increased angle you get out of moving it. I'm betting its basically a wash to be honest. At least for the small amount of movement we are talking about.

 

HHHMMMMM I am a tad lost on that one but then you could just adjust your spring compression to adjust for a small move ???? you think ????

I think you both have parts of the truth. [img]i/expressions/face-icon-small-happy.gif[/img] You could adjust spring tention to make up for some leverage, but Scott's point is also a good one. I think it depends on how long the swinger is, but in the case of a +4" you should only have to adjust the tension and it should be good. I'll find out soon on my K&Q fabrication +4" swinger.

 

Just my 2 cent's. When building my busa I made my top shock mount to long and I was running a 11" over swing arm and when you tried to compress the shock it would hardley move I had to shorten the top mount by a few inches and it changed the angle of the rear shock and it made a huge differance now it works like the stock setup I could not believe the differance it made.

 

This very democratic i like that [img]i/expressions/face-icon-small-happy.gif[/img]
