    What do you mean by "stiffer"? Shock/strut performance and ride characteristics are very subjective and are highly reliant on the driving manner, road type, and typical load rate of the vehicle.

    The 4600s have a compression damping rate of 815 newtons/.52ms and rebound damping of 3,325 newtons/.52ms. Compare that to the 5100 series which has a higher compression damping rate (965 newtons/.52ms) but a lower rebound rate (3,030 newtons/.52ms; to account for the coil preload asserted with the lifted applications).

    I went from the stock Tokikos crammed under a 2.5" DayStar spacer lift to the 5100s on top notch and my opinion is that both rebound and compression are far superior with the 5100s. I've heard folks call them "stiffer", but I wouldn't define it as such.

    Stiffer as in a firmer and harsher ride and less isolation from road imperfections. Not really too noticeable on fairly good road surfaces, but on ones in need of repair and brick roads, definitely noticeable. I usually find myself driving way under the speed limit on brick roads because if I go any faster I feel like too much stress is being put on the truck.

    Your tires are going to have a huge impact on road feel as well. What brand/size/ply/psi tires are you running?

    I have the 20 inch Enkei deep six XSP wheels. Tires are 295/45/20 Hankook Ventus RH06. I will be replacing them soon with Yokohama Parada Spec X's though. I ran those before the Hankooks and would of gotten them instead, but they were on national backorder at the time. First set of tires were BF Goodrich G Force KDW's I think they're called. Great dry grip, but tramlined bad and got extremely noisy as the tread wore down. I run about 35 psi in all tires.

    Those 45 aspect ratio tires are not known for giving a cushioned ride. You're going to have an awful lot of road feel regardless of what shocks you choose.
