Dirt Latemodel Spring Stacking Part two; Things to Consider When Stacking Springs

[@bryonkidder6199]

Thanks for sharing your knowledge! I luv the math and geometry that goes into making a car fast!...lol

Thanks for watching.

Thanks for the content. Started on your website and now watching you here. Started thinking about one of your previous videos on your combined 5th/6th coil. I was thinking a design for that could be an inverted pull bar…meaning more bumps in compression and less in extension…mounted vertically to the lift arm same as a 5th coil. Kind of like the Nueline lift arm but more compatible with existing car designs without having to weld. Thoughts?

I’m not familiar with Nueline lift arm or really the inverted pull bar. I think it’s important to have the shock incorporated right into it. When I was figuring it out, it was kind of tough leaving enough driveshaft clearance. I worked at it for awhile to get the spring rates and heights I needed to fit the shock. If you try it and get it to work, drop a thread in the comments. I curious. Thanks for watching.

We run multi bumps and packers on the actual 5th arm shock. The nueline deal seemed to be a good idea but anytime I’ve worked with it, at full droop it makes the car hop and bounce tight in the rear.

have you ever had experience with spring smashers? how does it work? how do you set the spring?

[@HoganTechnologiesLLC]

I have. I use them often and it’s a much better than conventional scaling once yo know your numbers. Here is a link to a video I did on them. Thanks for watching. kzbin.info/www/bejne/rnuUiaxubZmcn5Y

So basically the top teams at this point if they don’t run a RF stack, you see the 14 inch swift 175 on the right front. Soft and tall, but in barell form so you don’t have the same thing you talked about. Doesn’t coil bind at 4 1/2inch passed RH with about 3,000 lbs at 4-4 1/2 on the bump spring.

Ok, when we were experimenting with bump springs years ago, they were around the 1000 LB range. I was hoping to get that final rate around 500 with a little more travel room to work with. The forward drive on those bump springs is incredible. Thanks for the info.
