It is finally done! I have built my own 3-piece rear sway bar. All the cool kids have the ASR rear sway bar, but this kit attaches to the lower control arm making a full exhaust impractical for the street and it costs nearly $600. With a little creativity and some fabrication skills, mine came together with a minimum of wasted money.
Searching the internet it was determined the torsion tube wall diameter should be 0.188 and measuring the distance between the attachment points dictated a 42” length is the bar to order. Speedway Engineering makes the bars and HPR is the distributor I worked with. The bar was $92 and the aluminum arms were $45 each. The arms needed to have the adjustment holes drilled and the extra length cut off. Two inch angle iron was welded to make the mounting brackets that are bolted between the frame and the tie down brackets. My local bearing supplier was my source for the end link and mount bearings. Measuring the distance between the chassis mounting holes was a challenge with the spare tire well between them. Using a level, some spring clamps, and a couple of carpenter squares I was able to get an accurate measurement with this “caliper”.
The other challenge was getting the exhaust out of the way. The factory sway bar is a wire thinner than your little finger - clearance is not a problem. A 32mm torsion tube takes up much more room in this area. My exhaust guy was able to tuck a new section above the bar into the gap between the frame and the spare tire well, neat and clean.
The mounting brackets are angle iron with a gusset welded between the legs. They were trimmed a bit to get rid of some extra steel, they look better and now the sharp corners are a little safer. To avoid binding, there are three sets of mounting holes for the brackets. The whole bar can be moved forward if the stiffer adjustments are chosen.
We will see how well this new system will work this weekend, the Divisional in Kansas City.
