Spring and damping rate control squat in an IRS.

right... from what I understood from Frank... the issue would still be there, but there parts are more tolerant to the issue because of the beefiness of all the part... I think.

i just dont know why some of have this and others not. I only have a 1 inch drop... what about those with a 1.5- 2 inch drop... i would think that would almost instantaneously rip the boots.

or maybe the hp level has something to do with it too. haha.
But Russ had no issues when he was on the stock rear end with high HP... so I am still all

I know when I do get a new rear end.. from whoever... i will ask them to pre-pack it with a synthetic grease.

Also I think Frank mentioned that they now do a more secure banding than when they first started... i may have an earlier set.

which part do you disagree with? Mix-matching vendors?
