Can someone tell me what suspension device this vehicle has supporting the front axle?

Looks like a rod or possibly an extended shock absorber.

Three link suspension? Bill/Wagoo has posted about it before somewhere.

Diana, how much extra travel do you think the wider track will gain....if the front axle is at 45 degrees (how many would be???) 1 inch extra width will only gain 1 inch extra hight up the ramp....not really going to gain much.. what is important with Ramp tests is the angle of the front axle and the relation of the body/vehicle to this. Bill's rig is a very good example of this. What would be idea is having the axle at say 45 degrees and the body at 22.5

Some other shots I took of it. Don't ask me about its magic though.




Don't ask me about the magic inside.

Ah yes but Defenders and 110 are 5" wider hub to hub than a SII/SIII Land Rover and getting up towards 7" over an S1. The minimum rim on a Defender is 5 1/2" going up to 7" OEM while a 1948 series only has 4 1/2" rims

and most stock series have less articulation regardless of the track width....I have heard that 80 inch SI had ok flex due to narrow springs.....The RRC from the early 70s would be LR's best

I dont think FC's rate, Lightweights probably same as series IIA/3, 101's are the only LR with Parabolics but probably still not as good as an 80, The 110 lightweight never saw the light of day, nor the 127 "LARGE" trucks...The Larma while coil sprung, would be no better than a 90/110/130....but according to your methods, the LR forest rover with 52 inch tall tyres and wide front axle (note front was much wider than rear to allow for steering) would be the ramp queen...

I was quite underwhelmed with the lack of articulation I have seen in 101s, most standard series LR would articulate as well, the only saving grace for the 101 is the track width.

As for modified series leaf springs, with a few minor adjustments and lubrication you can get them to articulate quite well, at least as well as after-market parabolic replacements. The advantage with coils is that they can dislocate something that eye to eye leaf springs, like on the series Land Rover, can't do.

IRC Bill has a 3-link front with small diameter (car-type?) coils. The upper coil mound appears to be able to drop down as the suspension articulates.

Bill has probably explained his setup in much more detail in the link above.
