    I don't know which one to get. My truck is used primarily as a daily driver but I do get off-road at least once a month. I'm looking for a little boost in power. I just installed a new GM 350 a few months ago, but my 33s and 3.42 gears are killing my power. I hope to regear in the future and I thought that an MSD ignition would offer some help for now. Also what is the difficulty level in installing these ignitions? Thanks

    MSD ROCKS! I emailed MSD and asked the same question and the biggest diff between the two is that the off road version is completely submerged in that apoxy stuff were the 6A has just been coated with it. The comparison thaty gave me is you can run the offroad one under water were the 6A under water would, in time, fail. So the question is do you plan on submerging your rig in water?? Probably not. The 6a is what I bought and i like it just fine it stood up to water and mud from the trail and the hose in the driveway.
    Hope this helps

    Was it relatively simple to install?

    I'm also a huge Pens fan, but it looks like their season is going to end very soon.

    Yes, it is relatively simple.... The directions are very good and I think the newer models have nicer connectors. I had to attach my own connectors onto my 6a, but it is somewhat old.

    I would get the 6AL for a few dollars more. It has a built in rev limiter.

    MSD ROCKS! I have loved the msd Ignitions since they first came out. I am running a 6al in my truck. I love the rev limeter. I can't seem to lift my foot when I need to so it's a big plus!! If I didn't already have this box, I would get the off road box. I just got mine back from MSD agian for repairs. I keep blowing an internal fuse link. They said is was from blunt force trauma!! (hard landings.) I will most likely replace it with an off road one as soon as funds are available. They are easy to install.

    your right. I don't understand the jeep thing!

    Waste of money if you are looking for power. Get some better gears,headers, or a bigger motor, then worry about spinning your motor above the stock HEI's limits.
