All the new o-rings that are currently available were tested and the new purple ones were the best for smoothness and for good service life.
All the new kits are currently running the purple o-rings on the shocks.
I have not had any issues with any of my shocks running these o-rings.
I run boots on my 1/8th shocks but not on my 1/10th.
Just making sure you clean the shock shafts and the shock body end caps will help prevent contaminated shock oil over time.
