    Stinger , smitty built winch , cold air , 93 tune , 30 inch Cooper tires stock height . Will update when I do more
    My idea is to buy "anti jerk" product I purchased one for my 5.2 ZJ who has this same problem . Lucas makes great products but I'm sure u can find some thick additive that's cheaper meant to fix "transmission jerk" I hope this helped but again I'm just going off of what I read.

    5" lift, 4.11 gears, tru-trac limited-slips, winch, bumbers... you know the rest.
    The 5.7 hemi engine has 16 spark plugs and they are under the coils. This engine is a coil on top of the spark plus design in other words. ONLY! Use OEM copper plugs with this engine. If you change them yourself or go to a shop OEM copper plugs should be the only plug installed or the engine will have problems. Remember it 2 plugs per cylinder and they are good for about 30k per set. This is a temperamental engine. Always check for codes a common problem with these is the oil pressure sensor, believe it or not it will cause the same problem or even a no start as it shares a power with the CKP sensor.
