The only failures I’ve heard of was a blue 90 snapping the a frame ball joint at the tay forest challenge and someone ripping the chassis mounts off, so neither we’re failure of the a frame it’s self. There are plenty of other cars that have the same set up that are used far more violently with no issue. devon4x4 usedto make a billet a-frame extension to extend the fulcrum, PPcages make an extended tubular aframe that gigglepin use to great effect and Adrenalin4x4 make an extended tubular one with a rose joint at the end. So those are off the shelf alternatives but in all honesty I think you’ll be ok with the standard a frame. i forget where I got it from now but on mine I have a cast fulcrum replacement that allows me to use a creeper joint(3”Jonny joint) where I get a bit more movement than the normal ball joint before it binds and the axle is allowed a small amount of cushioning through the bush, it’s also now a double sheer setup throughout food for thought HTH out of curiosity, why extend it? Are you not keeping the 88” wheel base? Thanks for all that Extending the wheelbase by very little, possibly as little as 50mm By extending it I gain a wee bit more prop length, shortening the diffs has been a massive saving but finished diffs are still 50mm longer than Landrover diffs so that does not help with prop shaft length Where did you get your fulcrum replacement?

Regards Stephen I want to say it was WKD but for a man if your calibre it’s wouldnt be hard to make. you could probably get 50mm by making a fulcrum. Best of both worlds. im at my workshop now so I’ll finish what I’m doing and crawl under the 110 and take a few photos 1 Quote Link to comment Share on other sites More sharing options...

dangerous doug Posted April 1, 2022 Share Posted April 1, 2022 Can confirm you’ll get atleast 2” re making the fulcrum hope that helps, I pulled my back climbing under there😂 1 1 Quote Link to comment Share on other sites More sharing options...
Daan Posted April 1, 2022 Share Posted April 1, 2022 I'd say you can hang a london bus of that. I have a suggestion though: the single ball joint becomes a bit of a weak spot with those portals and large wheels. I'd be inclined to suggest that replacing the a-frame with 2 straight links with ball joints or bushes at the ends is far stronger, and easier to engineer.

Stellaghost Posted April 1, 2022 Author Share Posted April 1, 2022 I have another 30mm rose joint exactly the same as I'm using for the front so I could do something like this I would easily gain the distance I need, it would involve some modifications to rear axle mount, but that's easy enough The joint would allow axle to twist to 30 degrees, slightly more with a custom shaft what do you think ?

dangerous doug Posted April 1, 2022 Share Posted April 1, 2022 IMO that’s the route you want to go but bolt the a frame to the car to work the geometry, looks like your mock up just comes out the back of the a frame, that will work but the bushes at the other end won’t last long. My one has the joint shank about 3” lower than the aframe bilts Quote Link to comment Share on other sites More sharing options...

Not sure the length of my shocks…15” maybe? It’s not maxed out in the photo but pretty close. Tyres are 37” for perspective 1 1 Quote Link to comment Share on other sites More sharing options...

Just curious as to a cost per hour sort of thing (assuming you have to get your gas the normal way). Used a third of a large cylinder over about 4 hours, full cylinder is £95 so a little over £30 equating to about £8 per hour, not too bad really regards Stephen 1 Quote Link to comment Share on other sites More sharing options...
