Agree, Bils are more OEM with a tad more dampening
Didn't like my KYB MonoMax's at first. They replaced Edelbrock IAS's that had one destroyed hitting a Landrover that jumped a stop sign.
Loved the IAS's. As their valving more performance than anything, but they leaked with their upside down mounting requirement for the smart valve (senses rate of change, so has to be part of the piston rod). The down side to the IAS's is that they were painful going over speed humps/bumps...as they close down to almost a solid rod in slow going. Ditto that off roading...painful, but okay with me, as knew that...so just accepted it
MonoMax's valving is closer to performance than comfort, but on a heavy vehicle not total performance, IMHO. Like them so much on my Suburban...bought a set for my 1980 Silverado
Bottom line is if you valve ride quality over performance...get closer to OEM level. If you valve performance over ride quality, get the KYB MonoMax...of course in IMHO...as am a Boy Race since my teens in the 50's-60's...
