Long Travel BS Thread

The Tundra axle is use only for 1st gens, as the rear axle for the 2nd Gens is just as wide IIRC

 

i will be shocked if that cage is tagged

 

I thought we were talking about race ready trucks here... im sure its a nice cage but theres a little more to a tagged cage...

 

i have no idea, the Canadian brought him up to talk about weight.

You're gonna be over 4000lbs race ready with that thing, so you're need 2" tubing. If you wanna go hard, go with a 9" axle, not Tundra axle, cuz you'll be blowing gears. Also, depending on where you put your fuel cell with those links (preferable as far back as possible), you dont want to run dual vertical spares like that, for space and balance reasons. Have them flat, on top of the fuel cell, as far back as possible, to give yourself a low center of gravity.

 

I already have him building a 9" rear end to handle 600+ HP i know ill be over 4000 it just threw me off they said race ready.. lol ill have to rethink the fuel cell location and vert vs horizontal spares.

 

SCR34: ROLLCAGES
Best In The Desert Racing Association believes that it is each competitor’s responsibility to
present a safe vehicle for pre-race tech inspection. You must maintain your safety equipment
including the roll cage integrity. No changes to the recommended minimum construction
specification with respect to diameter or wall thickness are anticipated at this time. As in the past,
Best In The Desert Racing Association reserves the right to not allow any safety cage design that,
in the view of the tech inspector, is not fit for competition. You, as the competitor, are ultimately
responsible for your own vehicle’s safety features with respect to the design, quality of execution,
maintenance and repair of the roll cage structure.
All vehicles in competition are recommended to be equipped with a rollcage based on seamless
mild steel/4130 chrome molly steel tubing. Minimum design and tubing size for rollcage structure
is in accordance with Table 2.
Table 2. Minimum Tubing Dimension
Vehicle Weight
Under 2000 lbs. 1.5" x 0.95"
2001 to 2500 lbs. 1.5" x .120"
2501 to 3000 lbs. 1.75" x .095"
3001 to 4000 lbs 1.75" x .120"
4001 pounds and over 2.0” x .120”
Note: See manufacturer’s’ reference charts for alloy steel
tubing equivalent strengths. No aluminum or other
non-ferrous materials are permitted.
MATERIAL
Rollcage construction material may be crew, dom, whr, wcr mild carbon steel or 4130 chromoly.
4130 chromoly is highly recommended for all rollcage construction. Stress relieve all welded
intersections by flame annealing. All welds must be of high quality and craftsmanship with good
penetration and with no undercutting of parent material. Oxy-acetylene brazing on rollcage is
strictly forbidden.
ROLLCAGE DESIGN
All rollcages must be designed and constructed with one front vertical hoop, one rear vertical
hoop, two interconnecting top bars, two rear down braces, one diagonal brace and all necessary
gussets. The two top interconnecting bars must be placed as far to the outside of the top part of
the front and rear hoops as possible. Rear down braces and diagonal brace must angle a minimum of 30 degrees from vertical. At the bottom of the diagonal brace there must be a cross member of
the same tubing material and dimensions as the hoop. All rollcage components (hoops, braces,
gussets, etc.) must have a minimum of 3-inch clearance from the component to the vehicle
occupant’s helmets when occupants are seated in their normal riding positions. All portions of the
roll bar or bracing that might come into contact with the vehicle occupant’s helmets must be
padded. All portions of the roll bar or bracing that might come into contact with the vehicle
occupant’s helmets must be padded.
Rollcages must be securely mounted to the frame or body. All intersecting points must be
gusseted and braced. Cab or body mounted rollcages must be bolted through the body structure
and be attached by use of a minimum two 0.1875-inch thick doubler plates (one on each side of
body structure). Bolts and nuts must be at least 0.375-inch-diameter s.a.e. Grade 8 or equivalent
aircraft quality. Welding of cab or body mounted rollcages to body structure is strictly prohibited.
Rollcage terminal ends must be attached to a frame or body member that will support maximum
impact and not shear or allow more than 1.5 inches of movement in the cage terminal end.
All vehicles including those with stock steel doors must have at least one side bar on each side of
vehicle that will protect occupants from side impact. The side bars must be of the same tubing
material and dimensions as the rest of the rollcage. The side bars must be as close to parallel to
the ground as possible, be located to provide maximum protection to the occupants, and be
securely welded to the front and rear hoops. The location of the sidebars must not cause difficulty
in entering or exiting the vehicle.
Gussets constructed of 0.125-inch x 3-inch x 3-inch flat-plate or split, formed and welded cornertubing, or tubing-gussets made of the same material and thickness as the rollcage may be used.
Gussets must be installed at all major intersections, including diagonal and rear down braces,
where single weld fractures can affect occupants’ safety.

 

too long didn't read

 

when you are deciding where to but things, just think as low as possible, especially during those oh shit moments when you are cornering really hard and you feel your truck tipping....those two spares that you had sitting up all nice and pretty for the homies to see could be enough to send you over.

 

true but most horizontal spares ive seen whent hey have a fully built bed cage the one spare is almost touching the roof of the cab and the other is low.

 

Fuel Cell in the rear and Spares all the way back, on the fuel cell, flat:

 

i just mentioned what i expected to weigh and people suggested i could get under 4k race ready... i was just asking about shawks lol. atleast its LT BS not Grammar BS

 

i still highly doubt you can get a second gen under 4k especially linked

 

Seems pretty high up to me? i was thinking along the lines of what they have on the plow. the fuel cell kinda sits in the middle tho.

 

I found the reason!!!

im telling ya, it's the Canadian

 

plow also has a smaller fuel cell, IIRC.

 

I knew I wouldnt be close to that! I mean 2 people weigh 300-400+ lbs. add another 200-300 for fuel... that right there adds quite a bit of weight... not to mention all the cage work...
