rules for Full Stock Class

Rules for Stock Full Class

Anyone have a good handle on the rules for Score vs Best in the Desert

I'm building a truck right now, and want to heavily modify the suspenion but not move out of class (I just ordered the Score Rulebook, haven't recieved it yet)

My questions will be around making new a-arms, can shocks/springs extend thru bed or the hood--(or more importantly is anyone doing it now in SCORE, even if it is offically not allowed?)

Are body lifts allowed to get a taller suspension, etc

Truck is a Hummer with a 6.6 Duramax--sitting in a machien shop as we speak, ready for hard-coare mods

Just getting started, looking for eny expereinced help out there!!
thanks

I don't believe that you are permitted to fab control arms for the stock class.

Shock mounts should be open.

[reverhart]

Every truck I've seen (well Hummers) in the stock class have added brackets, etc to the control arms for additional shocks--wasn't sure if it was because it was easy, or the law retaining the orginal equipment.

[Curious1]

I believe the Hall's run a single (large) shock at each corner with stock control arms. You might want to check the rules as far as number of vehicles produced. I know there were issues for the Hall's with there H1 Alpha, since there were only a few hundred made.

[reverhart]

I would assume it isn't an issue anymore, since they ran and set a precedence, as well as some other hummers.
I've heard that some inspection points are strict--(Safety) but others are loose?

[MOSS2]

Heavily modified and stock class dont go together. You must use all the stock arms no holes in hoods or beds etc. Buy the rule books before wasting money. Go look at the Halls trucks up close. (Laughlin next race). They also sell parts for racing the things I believe so call them up.

edit: Some things are not inspected by Score at tech...but for example you have shocks through the bed and win, your competitors can protest and you are DQed after you beat your truck for nothing.

score rule books are available at

As recommended, read the rule book before making any plans

thanks guys, ordered the rule book last week
cleaning up frame, have body off-building the roll cage this weekend-
I do plan to be at the race in Jan, I've seen the hummers up close they use stock arms but welded more onto them for additional shock locations, and limit straps, etc.
I make parts for humemrs myself, and I've been toying with a new control arm design--that is why I asked

I'm at a point wondering if a Hummer could be the least bit competitive in a modified class--H.P. with the Duramax isn't a big problem, but the weight is.

[Scott F]

For a sanity check, take a hard look at Donahoe's Ford diesel. Personally, I would rather get a hummer than build a Hummer. But, whatever floats your tank.

the point may be is that you have to use stock arms but it is allowed to reinforce them. Hence heavily plated stock arms. If custom arms were legal they would probably be using those, no?

Generally material can be added to stock suspension mounts and pickup points.

All control arms must remain stock as delivered from the manufacturer. You are not allowed to modify them at all. Spring mounts must also remain stock. Shock mounts are open so you can add a shock mount to your arm but you can't reinforced other parts of the arm that don't have anything to do with the shock mount. You are not allowed to go through the hood with the shocks. But with the short travel of the Hummer you probably won't need to anyway. Body lifts are allowed. A few teams have gone through the bed with their rear shocks although the 2006 rule book states the only holes that may be cut in the bed is for the fuel cell only so it may be a rule change that just happened. But basically it is a stock class and so you are heavily limited on what you can do. If you really would like to go crazy with the suspension you should look at class 8.

When did Hummers come with Duramax's? I believe in stock full the motor had to be offered in that model vehicle in order to be legal.

Here is how the rule book reads word for word on suspension.

Front and rear suspension must be of same manufacture, shape, size and configuration as originally produced and installed on the chassis to which it is mounted. All suspension components will remain in the orginal stock locations and original stock mounting methods maintained. All components will be the original manufacturer's disign and must be stock as delivered from the manufacture.

A-arms, I beams, and front axles must remain stock as delivered on the chassis to which it is mounted. Suspension parts must remain stock shape, size, and configuration as delivered from the manufacturer. Stock pivot points must be retained. Front and rear springs must remain in stock locations and retain original stock concept (leaf, coil, torsion). Rates and capacities of springs are open.

[65Chevy4x4]

How much does that beast weigh. You'll probably need like 2.5: tube for that weight, or does score stop it at 2in for 400lbs and up.

[Alaska ZJ]

The New H1's have Dmax's. I damn near bought one when that happened.

front axles must remain stock as delivered on the chassis to which it is mounted

So does that mean that the rear axle is Open? Not really concerned about the Hummer but was thinking about other rigs.

I will start another thread for my other questions.

Ok, answer this question for me if you can, i am confused also. on my 1994 ram i dont think that the stock stamped steel control arms will make the whole 1000 miles, and if i reninforce them or change them, i move classes to what? class 8? am i correct?
there is no intermediate class for slightly modified full size trucks like there is for stock mini in the score rule book.

so what can i do?

[mudrebel360]

yea you would move to class 8 which is pretty much unlimited on suspension, just that the tires must tuck in the fenderwells i think. On our stock-full class we ran the rear shocks thru the bed with-out a problem and they mounted to the top of the leaves. Also no mods to the control arms or track/panhard bar either.

Carry lots of spares!!!

Seriously though yes you would have to run class 8. Too bad there isn't like a class 8s like the mini trucks have a 7s class.

[zoomy97acr]

Thanks.

no class 8s really does suck. So I'll carry lots of spares!!!!

[reverhart]

We were going to build trucks for stock full, but class 8 looks to be more fun

stock full is too slow--700 hp sounds better coil springs going away and replaced with coil-overs

[Samco Fab]

Stock Full/8100 class is a very competitive class, and they are not as slow as you might think. An H1 is a very good platform to build, albeit an expensive one.

If you get good springs made for the H1, you can get about 15" of travel in the rear, and 14 up front. You need very large shocks, probably the Fox 4.4 is one of the best choices. Now in Score and BITD, you can put the shocks through the bed in the rear.

You can not reinforce any pivot points or control arms in any way. However, some people get creative where they mount shocks, roll cage and skid plates to make stuff last a bit longer.

If you think a part wont last for a 1000 miles, you can make changes that will make the parts last. Sometimes you wont want to make those changes, but to drop from 37's to 35's, or like Donahoe from 39's to 37's is a bummer, but the only way to make some parts live.

You must also drive the vehicle that you have. You cant hit holes as fast as you want to, and complain that parts fall off, you must drive as fast as your parts will let you.

To say that the class is too slow, or that the rules are too constrictive is a cop out that people that cant drive with patience use, or when they get smoked by another stock rig, they move up a class for some reason All kidding aside, stock full and 8100 are great classes, and I would say more competitive than class 8, based off of the money Ford dumps into the class.

If you think the class is too slow, our H2 was 23rd overall at Vegas to Reno this year, and at the 1000, we were only 6 hours off of the pace of the overall winner with down time. Many races we beat the 1600 cars, and they beat us at others.

Wheel travel and super beefy parts are not the only thing that win races. Our H2 was the fastest production vehicle for the last 4 out of 5 races we entered, and we only have 8" of wheel travel in front and 10" in the back. Look at our puny tie rods and our massive amounts of useless sheet metal. Driving is a huge factor, and shock tuning is another.

[reverhart]

I was kidding about too slow
stock full times are generally faster than calss 8 in some races
Stock ful lis just too restrictive for the mods we want to do like mounting the cooling in the rear, we now have full coil-overs 14-16" travel, and we don't ahve many of the stock parts left liek the doors, they have been replaced with sheetmetal
I like your H2, I've seen it run a few times!!

[Samco Fab]

You can easily get 14 to 16 with an H1 with custom springs. Call Chad Hall, and he can get the barreled springs. Then you run a mondo huge bypass shock!! I fabricated suspension on some military H1's a few years back with King coilovers and 17" on all 4 corners. You will want to get the Billet Ball Joints from Rod Hall Products, they are one of the best mods to do for your H1, and they give more angularity.

Why do you want cooling in the rear?
The weight bias on an H1 race ready is still rear heavy, I see a front radiator as the best setup, with trans and oil coolers in the back to help airflow to the front radiator.

I figure I will do my best to try to convince you to build an 8100 truck, but no matter what you build, post some pics of your buildup!
