    There is no information in the specifications page on this and I can't find anything on Google, so here it goes...

    I gather that the additional front shocks were optional and controlled the axles movement front to back...Is this true? Does anyone know what the RPO code is for this?

    I imagine this would stiffen the front and not allow as much articulation, hence be undesirable...True?

    The reason I am asking is I think I got some front suspension problems, and the shock are my main suspect. I am going to go it cheap and get some Gabriels for now (as recommended elsewhere in this forum...) and hopefully fix the problem. I know I got only two right now the RPO is F51 : SHOCK ABSORBERS, FRT & RR, HD

    OK, the code in my glove box says 1Z75 and says "Front Quad Shocks". I dont know if this was there because of the trailering package or what.

    this does stiffen the front a lot, i had the quad setup, and removed a set and get better articulation, and a much softer ride.

    I believe it's there to stop bounce when loaded.

    My truck came with the plow package. Included with this plow package is the quad shocks (RPO 1Z75) and heavy duty front springs (1F60) among other things.

    I'm kind of glad I have them. The front doesn't wallow or bounce like with a single shock design. I could use some new front springs though..

    The actual reason that the truck came with dual shocks was to reduce shock fade. Both shocks together are supposed to be rated as if it was a single shock. If some one said that they had a rough ride, they must of put two regular shocks next to each other.

    i was the one with the rough ride, and it requires 2 different shocks because of length.
    i forget teh brand i used, but they were about$60 each, and used what were listed
    for my app by the makers, but it makes sense to use a much softer pair, and they
    couold act as one reg shock, but 1 quality shock does a good job and its cheaper
