I've got the full UPR Pro-series suspensions, both front and rear. The quality and fit of their products is real good in my experience. The anti-roll bar is the single best rear suspension component you can put on your car. The car will leave straighter, flatter and quicker than with anything else you'll try. Its not great for street driving though as it will tend to bind the rear under cornering. They actually recommend undoing the Heim joints if you're driving on the street.
I just installed their full chromoly Pro-series K-member with A-arms, bumpsteer and coil-overs. My 60' times literally dropped from 1.54 to 1.44 with the installation of the kit. It pulled about 75 lbs off the front end. Check them out at
