    For those of you who hate side terminal battery's because they always loosen up, do this.

    Take a battery bolt out of your batt, go to hardware store, Find a Stainless steel bolt, or carriage bolt (something with a head on it) that is about 1.5" long that matches the factory thread pattern, and buy a SS Nut or 2 for each battery stud.

    Take the bolt and bring the nut (2 of them if you want) all the way up on the head.

    Now, install the terminals and accessoories and whatnot, and put the bolt in the battery FINGER TIGHT ONLY. Now give it a LITTLE SNUG with a wrench. (don't torque it down, you will puncture your battery)

    Now, take the nut, and rotate the nut towards the direction of the battery. When it snugs, hold the bolt with one wrench, and CRANK down that nut (can go really tight).

    they will NEVER come loose. The 2nd nut works as a lock nut if you desire.

    This will even work on batteries that have stripped threads.

    You will NEVER have side post battery issues again.

    Hope this helps.

    I have one truck setup this way, will be switching the other. The thread is a common 3/8"x 16TPI National Coarse Thread

    Been using the jamb bolt method for years. A good tip to go along with it is to slip a large rubber cap over the exposed portion of the bolt. Safety first. :nod:
