on my dw8 i bent a new tube on the drivers side and put it in place of the banged up undersling tube.
i only alowed an extra 2" of travel, has anyone done the same thing and got more extreme.
the reason i ask is because on the videos of the rear suspension in the tool box section, theres a car witha 3 link and no undersling and that thing looks like the rearend travels like 4" down below the undersling area.
if anyopne has done somthing else then how did it work.
i dont have any marks on mine where the axle has hit it but i think thats because there may be a suspension bind at my jam nuts and my link mounts. its bent and looks like a nut impression.!!!

It is very possible that the reason you don't have any marks on the underslung or the housing is you are either topping out the shock on the left or the coil over elim. (if you are running them)before there is any frame contact.I know some guys that went to the trouble of hacking up the underslung instead of checking to see if it was possible to even get to it when the car gets up on the bars.Older cars have a problem with this because it wasn't a cool thing to three leg it and pogo stick it on the LR back then.

that could be a issue, i get the rear to come to the undersling but its just short of hitting it. i have moved my shock mount lower to help
i get about 1-3/4" of rear steer but i am after more. i use th lower plug and my links are 14-1/2" and 16" eye to eye.
just looking for the added edge after a season with a tight 4-z setup.
she was always tight off the gas and fast when on the gas.

I know guys that cut it out and replaced it to allow it to drop more. they changed shock mounts etc so that everything had enough movement. Then about a month ago they decided it was dropping to far and they had too much travel and rear steer etc. They chained it back up to where it dropped the same as the original(dw-8) and it was alot better.

I think alot of this has to do with the type of track you're running. I, too, have a DW8 4-link car and have cut and replaced the LR lower underslung with a greater drop. I was pounding the top of the underslung, but my track is usually very heavy and rough. I think it was hitting as the car was on the bars and bouncing through the ruts. I'm not too extreme on the bars- minimal j-bar angle with the pinion 2nd hole up, and I run the LR upper bar in the 3rd hole with the spring behind on the birdcage. Car seems to drive alot better since making the change, however Dman made a good point you need to take into account. The mounts on the birdcage may need to be adjusted so the shock and eliminators don't get pulled apart and torn up.

The problem we incountered with more bend in the bar was it would hit the track under braking upsetting the car on entry.Had to change it back..on a dirtworks a simply shock extender will make it hit the frame,I have seen alot of the latemodels are running a chain with a spring to soften the hit on the underail.

WE LET OUR DW8 CLEARANCE THE FRAME ON ITS OWN, THEN REPLACED THE BAR WITH ONE THAT HAD A 4 INCH DIP IN IT. THEN WE HAD TO EXTEND THE SHOCK, AND THE COIL OVER ELIMINATOR. NOW IT WILL LIFT &CARRY LIKE A NEW ONE.
