Great 2 part series! I have been into handling since Addco swaybars intro to me back in 1970. I then learned about the Watts Link and sway bars. This video helps me with on my next handling improvements in my 2001 S10 2wd truck. A watts link. I started with adding a 2nd front swaybar to the front like what GM did for the newer 1500 trucks. Mount the bar behind the front wheels. I did this and left the stock front bar in place. Tested it! What a big difference! I then did this in the rear. My S10 Xtreme has a rear mounted rear swaybar installed stock. I then installed a forward mounted rear bar and left the stock rear bar in its place! What a Big difference! I have done many improvements to the frame and suspension for handling. Lowering, bracing front steering brace, middle cross-member brace, and rear K brace. Remounting the battery under the bed behind the right rear wheel, adding 100 pounds of lead weight under my stock rear bumper, a K brace for my shackels like the Toytoa X runner pickup, body bushings,shocks, springs, steering shock, and more. The truck handles SO good now! Very balanced when I pitch it around and it still rides smooth on smooth roads! Tires which are 2007 Corvette C7 wheels 18s and 19s, are nice looking polished, but tires only last me 3-6 months when drive hard in the turns, and expensive to replace. I did buy a watts linkage kit a couple of years ago but it looks like a you compared to yours! Great Channel! Subscribed!

Should have lined up the pivot on the same linear line as the pinion. And weld the Watts link directly to the axle housing. Simpler, cleaner, etc. Plus it eliminates the flex of the tabs/mounting hardware holding the Watts link. Any deflection will be minimized and therefore the angles will be more accurate. Have a good day, Justin.

This may be a stupid question, or I might just be an inquisitive idiot, but could the Watts Link work if you placed it on its side on top of the axle? Like if you took the axle as it sits and rotated the pinion down to the ground, that orientation. Just curious. If it would work in that orientation, you'd be able to connect both links to the upper part of the frame. Loving the series. The new format is a little to get used to but it looks like you guys are getting it dialed in. I like it, keep up the good work.

@Fix_It_Again_Tony
4 жыл бұрын
This design has an infinite instant center. There is no rotation of the axle as it bumps and droops. For anti-squat, which I what I think you are talking about when you are referencing "bite", it depends solely on the angle of the lower links links compared to the angle of the 100% anti squat line. The 100% line is found by drawing a line from the ground under the center of the rear axle to the height of the center of gravity at the center of the front axle. If the rear lower links are at this same angle then the anti-squat is 100%. If the rear links are flatter than the 100% line then the anti-squat is less that 100%. If the links are steeper, then anti-squat is greater than 100%. In this setup (rear mounted parallel four link) the anti-squat will be positive when the links are higher at the axle than the frame, and negative when the arms are lower at the axle than the frame. I am assuming anti-squat will end up being positive at ride height, but we will see.

I keep looking at the rear trailing arms that are mounted behind the rear axle. It looks like the rear pinion angle is going to be at an increasingly BAD angle as the rear suspension moves through its travel. The further the rear end extends downward....the worse the pinion angle is. You may have to limit your travel with limiting straps or by some other means. I am a car fanatic and I have NEVER seen a rear suspension setup like this. Thanks for always including the math and geometry associated with building the parts.

To expand on Jasper Walls explanation, he chose half travel on his suspension because the watts link has "travel" too. So you want your watts link bars and 4 link bars both parallel to the ground at half travel so both systems have the same "swing" with full compression and extension. Now his "normal" ride hight could be any where in it's travel but typically if you are building your own chassic and suspension from the ground up you pick half travel as your ride hight. Not always depending on application.
@NTK_FabWorks
4 жыл бұрын
@Rik Burt by building it at “half travel”, or essentially ride height, you can put all the joints in a neutral position, so as travel changes and the joints move, they’re less likely to bind before they run out of travel. On road builds are a bit different than off road, as the travel is only a few inches vs 12-30” for the off road world. Either way, it’s a good practice, because it helps to avoid cutting things back apart later on.

It really depends on the chassis. On some vehicles, a forward parallel 4 link can run into body clearance issues (resulting in having to cut floor panels and not everyone wants to give up foot/seat space) or some frames are super wide and will narrow after the axle. I personally think he is working on this frame to go under an old car body due to the fact he cut the standard upswept "truck frame" rails and added a flatter "car style" back half. But we will have to wait and see because it's a secret.

You are a great fabricator and welder, Justin, possible the best on YT and certainly the best teacher/tutor, but I think you skipped the suspension design classes, or at least the explaining part 😉 With lateral forces they are applied equally through the Watt's linkage - one link is compressive and one is tensile - each half the force applied force between the differential and chassis. On that, the lower chassis link is going to have negligible fore-aft loading, and really needed to be braced for lateral loads, but that looks like it 'shouldn't' bend unless the axle gets a really substantial whack, and then you'll have more than that to worry about. With longitudinal leaf (AKA semi-eliptical) springs, the axle moves in an approximate arc around the fixed eye (AKA shackle), with the other end designed to be free to move forward and backwards while relatively restricted laterally, so the parallel arms should have been trailing. Still looking forward to the final result, as there are some good reasons for your setup.
