Front Beam Standard width?????
dakka68 - April 16th, 2008 at 02:17 PM

Hi, have bought an offroad buggy, suspension is minus the front torsion bars as previous owner was starting a coil over upgrade. I am looking to get it going with torsiona bars "sourcing at the moment" but how long is a standard front beam??? its a king and link pin setup, but appears to be a couple of beams put together, ther are 2 locating bolts (pins?) on each beam tolock the torsion bars. Currentwidth of the beam tubes is 1025mm, can anyone advise if this is standard/longer/shorter???

Thanks

Standard link beam is approx 800mm ridge to ridge
ie ridge is the seam of the plate ends of the beam

Thanks for this.
So do I cut a set in half to get a suitable length or try and get longer ones?

Would it be OK to run with no connection between the 2 bars in each tube?

Bit hard to see, but under the steering box is another set of anchors. can just see the edge of the lower beam anchor in the pic

mate, i was thinking bout this with some of your other posts.

my family has been offroading for 30 odd years so i hope i can help out.

when splitting and widening the beam, the norm would be to end up running four seperate torsion stacks. one for each trailing arm....................so if two beams were joined, it now should have two torsion centering points on both the top and bottom beams. not that they will be center anymore!

so yes, you will need to cut the torsion bars from two seperate standard beams. keep the stacks bundled together as they come out from the donor and cut them so you can use them in the same operational direction in your front end. this will help maintain their strength

let me know if that sounds right, picture says a thousand words if you can get one.

Thanks dumone, exactly what I wanted to hear!
Just need to do some measurements to see if I need 2 torsion bars or 4. hoping only 2 as they seem to be very hard to get a hold of..
