I have everything for a single swinger setup on the steering also but ran out of time. It will also probably help with how loose it is.

In my Bronco I ran two Bilstein per side in the rear. I don't know the numbers but they were for a Ford Ranger when used as a single shock. I know stock Bronco's did have duals in front but I am not sure about the rear oem option.

What does the rule book say verbadem. It's all about walking the thin line pushing what's legal. If is says sealed non-adjustable shocks I would tune up some rebuild able shock like the others have stated and then have them welded shut. That can be justified and everyone else will do it or let them re-write the rule when you are beating everyone.

Here are complete rules for stock.

1.2.1: Stock Trail Vehicles. This class is intended for vehicles in stock form with very little suspension modifications, limited in tire size, and performance modifications.

1.2.1.1: All stock trail class vehicles will be required to meet the Dirt Riot minimum safety standard requirements, which include; 4-point harnesses, solid metal hardtop over a 6-point cage that is tied into the frame of the vehicle, solid metal doors or door bars that extend from the b-pillar at shoulder height to the a-pillar at the ankle/knee height, 2 – 2.5pd rated fire extinguishers.

1.2.1.2: Frame: Stock Class vehicles must retain the entire stock chassis. Chassis modifications can be made only to strengthen the frame (adding material).

1.2.1.3: Body: Stock body must be maintained, trimming of fender wells is allowed for tire clearance only. No “comp cutting” of rear corners is allowed. No ‘boat siding” is allowed. No cutting of floor board material is allowed.

1.2.1.4: Drive train: Drive train modifications are limited to internal up-grades of axles and gears, all stock class vehicles must retain drive train components that were available to that vehicle from the manufacturer.

1.2.1.5: Suspension: Lifting of a vehicle is allowed as long as no other rule for the class is broken. Only non adjustable shocks without coil carriers or air charges are allowed. Non adjustable, non factory bump stops are allowed.

1.2.1.6: Tires: Tires are limited in max size to 35 inch diameter by sidewall designation, if a tire appears to be greater than 35 inches, a measurement will be taken to determine if that tire is acceptable.

1.2.1.7: Steering: Aftermarket steering components are allowed as long as no other rule is broken. Ram assist steering is acceptable, full hydro ram steering is not acceptable.

1.2.1.8: Fuel Cells: Stock fuel tanks can be retained as long as the vent is routed to eliminate spillage, and a non vented gas cap is used to prevent spillage.

1.2.1.9: F-Toy class legal vehicles may enter Stock Trail as long as they meet the 35” tire rule.

1.2.1.10: Window nets are highly recommended.

Ok. So you can do the adjustable ones in testing and get them tuned. Then have the welded to the can't be adjusted. This follows the rule that you are racing with shocks that can't be adjusted.

I see it that I can do it that way also. I wish they were clearer on the way the rules are so vague. I never got them to even say what a charged shock is in their eyes. They did come back that a junk rs9000 is illegal being it can be adjusted.

9000' s were junk anyways. I don't see anything about dual shocks either.

Also, run some hydro bump stops. It will help smooth things out on hard hits. Don't forget to run limiter straps to save the shock from over extending. The shocks will last longer.

Another thing you could get away with is a coil spring insert from AutoFab. It acts as a secondary suspension to soak up the hard stuff.

Thanks for sharing experiences and updates!

We have about a month before the first race this season. Were looking to install some f53 or g80 deavers in the rear. I have to call them Monday to discuss if they think I can cure my rebound issues with a set of their springs. We also need to plate the beams and arms plus install the rcv shafts in the front.

Why did you mount the rear shocks under the bed? The ratio changes when angles so steep. If you can go through the bed you'd be able to run the longest shocks you could find. Not that you need incredibly long shocks but the volume will help them last longer.

In my opinion you should petition the sanctioning body for tunable shock as a safety issue. Limits on length and positioning make sense to me but having untunable shocks that melt down every race is unsafe, lends to difficulty maintaining proper control of the vehicle and isn't cost effective.it doesn't level the playing field either. It just takes more money to get legal shocks which negates the reason of having a stock class.

The only reason was to gain travel. The class allows no cutting of the floor board so with them leaned id say I have 12" or so rear travel versus a jeep with maybe 8" I still think they will work once I get some springs in the rear. Now they are just a stock set with a long stiff add a leaf added. Compression side feels great but the rebound is way light. I am hoping this is due to the spring pack. Also the melting down of shocks was on a grand Cherokee we ran before. The bronco even with the rear valving issue is a ton faster its just loose.

On paper the Bronco is a winner. I don't think there is another stock class rig that will run with one due to the class restrictions. We ran with the class above us at the last race and we were not the slow ones. We ran 3 laps with the second place overall rig trying to get around us and failing till we lost a fuel pump relay. They would catch us in the climbs and rougher areas but once we got some room we were gone.

Ordered a custom set of Deavers the other day. Have high hopes for the springs. After talking with them we seem to be on the same page on what I'm after and they say the custom race pack will do the job.

The rcv shafts are just insurance. We have not broke a stock shaft yet but also so far we have only raced in high range. The first race coming up is a harder track that will have us in low range so I want the rcv shafts.

As for us being slow in the rough the rig we were out running is a full tube buggy with a 6.0l chevy, 4 link front and rear with resi 2.5" coilovers on 39" tires. Probably 30k to build. They got led by a ill handling $3000 1986 bronco with my wife at the wheel with only 20 minutes seat time ever in the rig before the race.

With that being said we have high hopes this year in our own class.
