New "level 1 series" is made from a 1.5 square tube. The lowers have end tubes with .120 wall, and the uppers have a .188 wall end tube. Also, the U-brackets on the uppers got slimmed down a little. We also used a new design for the stock swaybar provisions that saved some money. There is a spacer bar down inside that is tacked in place that keeps the square tube from crushing when bolting up the stock swaybar. Basically went with the idea to make a line of these that were much stronger & stiffer than stock with a much improved bushing, but also compete with the entry level stuff that our competitors offer. Ours will still out-perform our competitors version in strength & performance, and they look better too! These are GREAT for stock upgrades & improved handling & drag racing, and are complimented WELL with our swaybar/anti-roll setup.
Our Regular line that we have been making/selling for years is made from 1.5 x 2.0 rectangle tube (stronger/stiffer). The regular lowers have end tubes with .188 wall (1/16" more), and the matching uppers have a .250 wall (1/16 more). Also, the U-bracket on the end of the uppers has more size/area to it around the end and where it bends for added strength/integrety. Basically somewhere in the 11's seems to be where people should look to our "regular" lineup to gain added strength and performance advantages. Plus our regular line adds the option of going +1/4" on the lowers for added pinion angle, and offer the uppers in adjustable design too. These are also available with our "Extreme Duty" bushing upgrade, which the Level 1's are not.
One other IMPORTANT distinction between these Level 1 Series uppers & lowers compared to our "regular" arms is that on the Level 1's, the bolts and bushings for the upper rearend ears are available separately. We did this to keep costs down for those that wanted improved performance but might want to save by using the stock bolts and maybe already had upgraded bushings in the upper ears on the rear. Also, this way you guys can order the Level 1's with a std poly bushing or our "regular" custom greasable setup for no binding or squeaking. Might even price our regular line the same way, so people can compare apples to apples with our stuff and with our competitors. Finding out none offer a greatly improved bushing for the upper ears and grade 8 plated bolts with the arms as "standard" like we have been doing for years!
