Offset locks to replace exhaust rotator retainers
Mmmmm... doesn't your closed pressure change vs installed height say a spring rate of 500 lbs/in? 50 lbs difference divided by 0.1" = 500 lb/in. Not a stock spring rate.....
Or are you saying the installed intake spring height changes from 1.6 to 1.4" with those parts on the exhaust side?
