Default Anyone have CalTracs on 1/2T NNBS?

Has anyone installed CalTracs on your 2wd? I had installed a DJM rear drop, but don't see anyway their bar can be installed.

I have an '11 reg cab shortbed.

If you have installed successfully, what kit part# did you use and what OEM parts did you have to modify if any? Any pic(s) you could post would be helpful.

Thanks, David

To LS1TRUCKGUY & tallChevy:

Here's pic of the DJM 3" rear drop only, which is combo of shackles and removing block, then flipping the U-bolts. Once you flip the U's upside down, there is no "flat surface" under the axle to mount the back end of a CalTrack. Even if I removed the overload leaf (same situation except truck sits even lower) I'm still stuck with no "flat pad" under the axle to mount a CalTrac even if I install OEM U-bolts.

Since I'm new to susp drops on trucks, particular those with axle under the springs, I need specific help and appreciate all suggestions. Thanks. Searches have not helped.



The righthand pic shows the OEM parts. If you re-install the OEM squared U-bolt with the top plate, you can see the part which the U-bolt clamps against bottom of axle has a curved surface.

UPDATE: Hey guys, just got an answer from Calvert Racing. Their 3400 kit replaces the saddle at the bottom of the OEM squared U-bolt assembly. It still has the saddle to clamp against lower part of axle but has been modified so that their bars work similarly to axle-on-top suspensions. I'll leave the above in case anybody else runs into same question on their NNBS truck. I also ordered the last of 2 pair of their "old style" x9000 rear shocks. The new ones they are bringing out will be more ride-quality oriented rather than drag-oriented. Thanks to you guys who responded.
