Has anybody else had trouble with their pinion plate bending under regular racing conditions? We run a 2-link DW-8 with a biscuit type j-bar, & have had to replace ours several times. They seem to bend back towards the rearend, & down right at the bolt that goes through the heim on the j-bar.We even went as far as running a long bolt through the bottom hole,(we run second hole from the bottom), and up against the 3rd member to try & support the plate, & it still bent right at the bolt again. Any ideas guys?
P.S. We have a 1" spacer on each end between the heims & the mounting points as was DW's advice. Thanks.

WE have had that problem as well. some reason it is more common with the jbar than the short panhard bar. If its not bent to bad we have taken them off and straightened them then reused them. You can try going to a shorter spacer on the pinion end. that will take some of the leverage off teh bolt. just make sure you dont end up with any binds in the heim.

sounds like something binding to me.I know on my Harris I run a two inch spacer on the pinion end to keep it from binding. i run the Afco plate and never bent on yet.

We have taken them & flattened them back out on a press, but they just bend again. I really don't think there are any binds, as the car seems to move very smoothly when we bounce on it & move it side to side. Plus the car handles great. Maybe a shorter spacer would be the ticket, but I don't want to get too much angle in it from the frame mount to the plate either.

think of all the forces on one, they should bend more often then they do.

I agree with zero, its amazing they dont bend every night. I often wondered about trying to make some out of 5/8 or 3/4 plate, but on the other hand Id rather bend and replace the plate than tear up the frame mount or rearend housing or something else on the car

Good point dirtbuster. I would much rather bend a plate.

We ordered our through DirtWorks, & it is a Southwest Speed Equipment brand I believe. We bought one last year from our local race shop,(it was made locally), & it bent also. The holes on it were located alot different,(lower) than the one from DW.

Your car seems to be very tight off. I don't know if that has anything to do with it, but it seems like Benji really has a hard time getting the car to turn under power and on exit.

Yea, we're kinda struggling with these tacky tracks. I'm letting him make the calls on the changes we make, & I don't know if he's afraid of making the wrong call,(he doesn't like to be wrong), or if he is just too lazy to make the changes that need to be made,(not very ambitious either). LOL. He said Fritsen was really slowing him down entering the turns last week, & that was making the car tight through the apex & off. If that's the case, she ought to fly once he gets out front. Maybe someday we'll see. Later Corey.

I think if you got out front you would walk away from them.

Looking at another reply they talked about rear springs and said that a stiffer right rear should make you tighter in and looser off. I am thinking about trying this on Sherwood's stock car. Have you thought about trying that on your car?

we also had trouble bending pinion plates, and not finding a bind anywhere. After having a new rear clip put on the car, the frame mount was moved back about an inch and haven't had trouble bending any since then..

Just bent a brand new AFCO plate Sat. night. I have to keep about 1" of spacer to avoid binding. It only bent a few degrees. I think I'll just run it and see if it gets worse. This track has about the fastest corners you'll ever get on dirt, with some ruts also, so g-loading was high.
