    for a mid travel front set up, id like to add either 2.0 air bumps or light racing jounces. thoughts? the light racing jounces are really expensive tho! :eek:

    so what are the benefits over the other of the two?

    I think the jounce bumps are just nitrogen charged, no valving.

    Hydrolic bumps like Kings, Foxes, SAWs, etc, are valved and can be rebuilt. You can set them from 100 to 400 psi depending on your setup.

    I rode in a truck with light racing jouce rear bump stops and my back hurt like hell after the ride.

    length of travel doesnt matter, it is the way it is charged/valved.

    Hydro bumps only have a little bit of valving, but it is the charge of the bumps that affects how hard they soak up the hits. I dont think you can change the psi on the jounce bumps.

    It sounds like you want the jounce bumps, buy them and give us a full review :)

    Either will work fine.

    I'm running LR Bumps in the rear since I got them at such a good deal. They have served me well for what they do (they took awhile to get properly tuned tho). I don't think I'd recommend them for highspeed uses.

    Reg. Hydro/Air Bumps will be cheaper initially & depending on where you get the fab work done or if you do it yourself it could be fairly cheap. They will also hold up better for highspeed uses.

    Yes you can change the PSI in LR bumps as well as the rebound & compression at the turn of an Allen key.

    I'm thinking jounces for the front and hydro's in the rear, this is all down the road tho.

    really? then how come you cant tune them to work at high speeds? They sound pretty good then

    You can tune them fine for highspeeds more for the high heat issue & the durability of the internals that I see as the problem. Mike (Defined) does well with the Donahoe Chubby's (essentially the same) on the rear of his truck tho.

    Not a bad plan, but it'd probably be cheaper just to run hydro bumps on all four corners :cool:

    That was also with my midtravel rear, LR's PSI was really low, and it was in Barstow :eek:

    As mentioned above Mike and Defined has them on this truck and does well with them. I have high hopes for mine once my rear is complete and can start tuning them.

    sounds like they're pretty cool then.

    My buddy Anthony250 has OEM replacement rear leaf pack and mid travel shocks with SAW 2.0 bumps and he keeps up with me in Barstow and Lucerne

    It's like anything, that goes without proper tuning :cool:

    after going out a few times with my new front the rear is the weak link, but i haven't don't my shock hoops yet, plus when i get a bumper, tire carrier and carry my spare, the weight might help smooth the expos out as well.

    Don't want to burst your bubble, but without an extra 200lbs+ over that it won't exactly be a "smooth ride"
