Tubular K Member

I've heard stories about Magnum Force also when I researched their K frame. I also know of people who've had no problems with it. It is pricey though and yes the upper shock mount needs additional bracing. It was never meant to hold the weight of the car.

As for the other units I can only say that I've heard nothing but good things about the Alterkation. I've heard nothing about the CAP K frame.

I will say though that for the money they get for some of these units I'd rather just go with an aftermarket front strut clip. That way you get lightweight brakes and a rack and pinion unit. Tons of room to install any engine you want and header clearance beyond your wildest dreams. Not to mention probably at least 500 ugly pounds off the front of your car.
