Looking at different setups for a hilux rear suspension.

eg. A-frame, 4 link, coil, air shocks ect.

gonna be startin on a triangulated 4-link on the lux soon just have to work out the geometry the rest is piss easy. u want it setup for speed or slow with flex?

What would be the difference between the two?

the winch trucks all seem to run A frame 3 links where the rock crawlers run a 4 link design. couldnt tell you why though, but it was alot easier for me to set up my a frame than it was to DESIGN the 4 link i was after.

1200mm lowers.
940 mm uppers.

the best photo ive got atm i think

Nice:)
Was there much geometry involved or you just going off other examples? Like with triangulated 4 link there is alot of calculating to get it right.
Willy: if this is off topic just let me know and i'll take it to PM. just though it might be relevant

Been told there's stuff all differance between a-frame & 4-link. Got the 4-link calculator off pirate but it's beyond me to work out.

Do ya keep the top & bottom arms parallel. The ones I've seen on pirate they don't.

????????????

nah all triangulated. i think the norm is to go the uppers from pumpkin to chassis rails and the lowers from outside of diff to middle or a crossmember on the chassis

if you dont triangulate the lowers on a 4 link the axle moves out to the side when the suspension cycles. on the 3 link the lowers are straight. there is sweet FA involved in an A frame, in mine the links converge slightly to raise the anti squat a little (still only 75%)and the links i kept the same principle as a 4 link (70% of lowers). then the uppers separate as much as i couldin the space available.

mine is in no way perfect, but for a first attempt (1st didnt really count as i did it REAL dodgy). it still needs bracing and other than the trussing on the diff i had to do it took 4 hours of work.

How do you calculate the anti squat for an A-Frame? Was there a website you found specifically for A frames or just going off other photos you have seen?

4 link calculator and put the upper with 0 separation at diff end
