bkabina Posted February 11, 2004 Report Share Posted February 11, 2004 How many people Drag in the dirt?I was wondering if you use the rear shock or if you use a strut.With a rear strut it seems like you lose traction,so wouldn't it be better to use the shock?

bkabina Posted February 13, 2004 Author Report Share Posted February 13, 2004 Most dirt drag bikes use a solid strut in the rear. Not trying to be a dick but I know this,I spend alot of time at the drags.I just don't know if there is a special reason people use the struts if a shock helps you hook up better.

alcoholbanshee Posted February 13, 2004 Report Share Posted February 13, 2004 I have tried both. I think the strut works much better. I have 1.5 short times on dirt with the strut and 1.7 with the shock ( Marvin Shaw). I have tried the shock at different pressures and it never got better. The wieght transfer was just really bad. The stock shock is even worse than the Marvin. I spin real bad with the stock shock. My motor is a 85 horse GRR Alky drag motor on a GRR suspended drag chassis running 4.40's on dirt. But the results were pretty much the same with the stock frame. Now I have heard of some people modifying the rear Marvin so there is a minimum of travel and it works real well. They let out all of the nitrogen then fill it with oil so the shock only has a inch or so of travel. Then you fill it back up with 600-900psi of nitrogen. I have heard real good things about this setup and will try it this year. Quote Link to comment Share on other sites More sharing options...

badcompany Posted February 14, 2004 Report Share Posted February 14, 2004 we run a shock, everyone here who is fast runs a shock. everyone with a strut spins out the hole, the only reason they run one is to keep the front end down. Quote Link to comment Share on other sites More sharing options...
BansheeEaterKXF Posted February 14, 2004 Report Share Posted February 14, 2004 well what works best for me is a stock shock tied down almost all the way leave about 3-4 in of travel and you will come out of the whole like a rocket but the reason people use strut so h.p. an torque get to the ground faster but with a banshee stock tied down works better than strut cause they have so much wheel spin a 250r or lt500 dont have that much wheel spin and thus is why they use struts Quote Link to comment Share on other sites More sharing options...
big_block_banshee Posted February 15, 2004 Report Share Posted February 15, 2004 i think its all in the setup , personally i run a shock, but i have seen someone run a 6.86 in the 1/8th mile( on dirt ) wid struts front and rear. im goin to try a strut in the rear this year to see if it helps me or hurts me.

Lightninn2 Posted March 3, 2004 Report Share Posted March 3, 2004 One thing to consider also is that a strutted rear end is much more consistant than a shock. The quad will react the same each time during the launch as far as the suspension is concerned. It essentially takes one of the changing variables out of the equation. As a shock begins to heat from multiple runs, it's motion will change as far as compression and rebound speed. A solid vs. suspended rear end will require different set ups in tire selection and/or tire pressure to achieve optimum launch at the line.

Southside Motorsports Posted April 1, 2004 Report Share Posted April 1, 2004 I run a 565 10 mm w/ a +12 and marvin shaw shock....I don't see any one who runs those goofy struts at any tracks In MI except for asphault. I do know that your bike needs weight transfer coming out of the hole on dirt and sand and there is no way that a strut will do that. So i see no advantage to running a strut.

banshee tuner Posted April 2, 2004 Report Share Posted April 2, 2004 The bikes I've seen run with struts was to lower it and leave full throttle on pavement. But they spun worse on grass or dirt. Quote Link to comment Share on other sites More sharing options...
Forcefed Posted April 3, 2004 Report Share Posted April 3, 2004 IMO...AlcoholBanshee and Lightninn2 are right on. I do know that your bike needs weight transfer coming out of the hole on dirt and sand and there is no way that a strut will do that. Think about it....both a strut and a shock transfer the SAME amount of weight...why wouldn`t they? The main variable involved is the amount of TIME that it takes to transfer this weight. With a strut, the weight transfer is instantaneous...(and consistant every time) With a shock (depending on valving/settings/rider weight...and so on) it takes TIME to reach 100% of the weight transfer. And yet another thing to keep in mind, ALL shocks have some kind of rebound to them (otherwise they would`nt be a shock) and at one point or another that rebounding effect is going to try and do just the opposite of what you are trying to acheive with weight transfer. I`m not saying a shock is bad.....just different, and before you knock a strut...try it. I ran with a strut last season, on dirt, and in the latter part of the season, managed a consistent high 1.4 second 0-60`. As Lightninn2 said.....it`s in the SETUP !
