Not true. The sway bar works the same on left & right hand corners regardless of any arm length differences on opposing sides. Ours have 2 holes in the arms, but you can split the holes with one link to create a third rate halfway in between.For example ONLY, if Clients RACE-STAR car ends up around 3200#, we utilize our 1.25 x 34 x 1.350 OD Step Up Sway BarIt is a 3-piece 4130 chromoly splined sway bar from Speedway Engineering. The sway bar mounts under the 34 wide OEM frame & the sway bar arms are under the frame as well. This adds inner tire clearance without causing any issues.With our 45 steel sway bar arms the 9.25 long holes provide a 1456# rate & the 8.25 short holes provide an 1830# rate. If you put one link in a short hole & the other in a long hole, you split the rate & have 1643#. The lower the rate, the more grip up front & less in the rear. Conversely, the higher the rate, the more rear grip & less in front.Ron engineered this setup to run the softest 1456# rate on tight, slower corner speed road coursesthe 1643# rate at average corner speed road coursesand the stiffest rate of 1830# for bad fast tracks with long, fast sweeping corners. If youre at a track and need more rear grip throughout most corners, adjusting your front sway bar stiffer adds rear tire grip. Just the opposite if you find you need more front tire gripsimply adjust the front sway bar to be softer.Many racers automatically run the softest rate on super tight courses & the higher rates on courses with more open radiusand higher speedcorners. And its quick & easy to adjust if you find you need a little more.One key thing: When you are splitting holes, you dont want to accidentally put any preload in the suspension. So, you do want to find a spot in the pits where when you unbolt one link, the sway bar arm doesnt spring away. Or simply jack one LCA just enough to have the bolt come out easily, with no bind. Then adjust the link length to bolt in the other hole, without binding. 1164'
