DIESELWRKS and MVandever...
The current bars on my truck are the EEP bars,or whats left of them anyway. The only EEP built parts left are the rear mounts and the shackles up front. I did not weld the shackles on my frame as I wasn't sure if I liked the look at first. When the initial install was done and I got home a local chassis man removed the front shackles and welded tubes into the places where the bolts slipped through the frame for strength. This way when they were properly torqued down it did not crush the frame at all and they stayed where they werer supposed to and did not egg shape the holes. I have the top bars but you can not run them on the street as it makes for a rigid mount and not much rear suspension give.
The original EEP lower bars on my truck were bent bad when the truck was lifted for transmission work. Seems they were a little thinner than what they should have been and it also explains why so many have been bent in a single bar form. The bars we replaced them with were built by East Coast Diesel Performance's chassis man and are strong.
For simplicity... .
Darryl Poole's bars can not be beaten,period. They are tough as nails and will handle any abuse you can through at them and are used by many Midwest pullers. Again,having to do it over I would have kept my originals and been done with it... ..... Andy
