Not recommended for lowered trucks, even though they say it'll work.
Ad says the system provides adequate clearance for substantially lowered vehicles. I have a '75 C10 long bed, 454 with long tube headers that has an axle flip (lowered about 6.5"). Nothing extreme. I had to modify the front hanger because the axle was going to hit the exhaust (by an INCH!) if the suspension was fully compressed. Raising up the front hanger threw off all the other angles. Also, the primary park brake cable mounting bracket had to be removed and re-located. Almost 6 hours of cutting, bending, flaring and welding later, it's still not done. I may just dump it if front of the axle just to be done with this job. I have a shop with a lift, air, welder, torch, band saw, etc and I'm having a hard time with this kit. Not sure how a weekend warrior working in his driveway could install it. I'm installing it on my personal shop truck with the hope to sell these to customers. Not going to happen. My exhaust guy is $850 for a 2.5" dual Flowmaster setup. Way better deal than the hassle of this kit. If you have a stock height truck, it should be easier. Lowered trucks, good luck.
