204 MMF Step Up Sway Bar Kits When we run a 1.25”-spline bars with our 8.25” – 9.25” Arms … the highest rate we can get is around 1300#. If we go longer on the arms, the rates go softer. We can’t run any shorter arms … without experience too much angle change in the arm as the suspension travels. I think of these 8.25”-9.25” arms & 1.25” sway bars good up to 3” of front end suspension travel in dive. More than that & we have too much arm angle change & we would most likely bind & break the rod ends … or something else. To run more travel, we need longer sway bar arms. When we do that, the bar diameter has to jump up significantly to get the rates we want. That’s where the 1.75”-48spline bars come in. With those big bars we can get rates up to 5000# if we wanted. We don’t. The most I run on my mean road race cars is about 3000#, maybe a little more. I run a lot of cars in the 2000# to 2800# front sway bar rate range. Can we get here with a 1.25”-48 spline bar? YES ! As long we’re not diving the front end more than 3”, we can use our 8.25”-9.25” arms … and get rates from 1400# to 3000# if we want … with “Step Up Bars. A Step-Up bar, is 1.25-48 Spline out at the ends … but just inside the bushing, it steps up. How much? Depends on how much rate we want. Check out the rate sheet on the following page.
