I'm looking for a replacement for both rubber pieces for my pullbar. I was told by a few people that I would find the main rubber at a Kenworth Truck Dealership but no such luck -- I just got a lot of weird looks when I said it was for a racecar!

Any ideas???

I had heard they were the cab support bushings for Kenworth before, but I dont know what model or year or anything or if that even applies.

But, I am pretty sure you can get both of them through Dirtworks if not other suppliers.

I run the same pullbar its called the edge built by John Hardesty they sell three different rates you can reach him at 785-392-2048 or 785-392-2564 or 785-392-7519 to order a new biscuit. I can not tell you the rates he sands them off. There is also a place in Topeka called Truck parts that sells them that we were going to start getting ours threw but we do not have a rate so it makes it hard to.

Afco racing sells them, but they are expensive, around $70. Part #20420 3 different hardnesses, 45, 55, 65 durameter ratings.
I'm sure there are cheaper vendors.

Is this a pretty outdated pullbar? Would I just be better off purchasing a better one?

We ran it last year and are using a spring bar this year, however, we wanted to change back becasue we have not had much luck with the spring bar. I'm not too sure how to check if the biscuit is worn out or not.

02 Racing - Do you know what the TruckParts store calls this biscuit? Is it the cab support bushing for a Kenworth like dirtbuster mentioned? I went to the Kenworth Dealership here in Kansas City and they couldn't match it up to anything.

Thanks.

I wouldnt necessarily say its outdated as many people still run them. Personally i think the spring bar is better because you dont have to worry about whether your bushing is losing rate. I know some guys that were wearing them out in 2 or 3 nights on a heavy track. I was told if they lose 1/4" in free height from new then they are worn out.

What spring are you using on your bar? Also what kind of rear suspension? What kind of bar also?

We are running an Afco spring bar. 700lb spring, 39" long @ 17degrees. DW-8 - short left, long right 2-link. We get around 2 - 2 1/2 in. of travel on the pullbar. J-bar at about 4" of rake.

It just doesn't seem like we have as much foward bite, although we have been messing around with the angles on our trailing arms a lot. Last time out we were at 10* lr (bar @ 13"long) and 5* rr (bar @ 21" long)...so it might not be a problem with the pullbar at all.

That biscuit looks very similar to what is on the biscuit bar I got from Larry Shaw Racing in Batesville, AR. I'm not completely sure, but I think they also come from D&M Race Cars. The biscuits from Shaw come in three colors, 3 different rates. The purple is supposed to be a 1050#.

sdracer is right. Looks like the same stuff I run that I get from shaw. Call them with your info and ask them what they think you need.

I do not know what they call them but yours is different than the ones everybody is talking about it looks like mine they are bigger than the one that goes in the monty bar and they last a long time mine has 35-40 races on it and we compared it to a new one on spring tester and it has not changed. I can call and see what they call them all I know is there for cement trucks toward the back were the cement is and is used as a shock absorber. The Edge is what mine is called and the company is only a couple years old. I like mine better than the spring bar it improved bite evey were on the track. John Hardesty at the Edge sells three bisquits soft bisquit for 2-link a medieum for z-link and stiff one for 4-link. If you want me to call let me know there like 40-45 dollars for a new one at truck parts and they actually have more then three rates if you go there.

The small bushing in your pictures will be a one half of a radius arm bushing off a Ford truck.

The company that Really makes them is TIMBREN , they are used on the big rigs and also as over load springs, for a 1/2 ton pickup. plow truck overloads. they are fairly pricy. thats why afco get $70 each. The one i have only says made in canada, type 515 and Timbren.
