I agree with Corey. Unfortunately, despite my statements and others with considerable knowledge Rob S. does not understand that Suspension Techniques bars are just as difficult to install as Ireland Engineering bars. They all use the same bushings and the bars have to fit in the same hole in those bushings! This is why urethane is used Rob! It is used to decrease the deflection of the stock rubber bushings and therefore give you better bar reaction. Unfortunately, the price you pay comes in installation because now the urethane does not give like the rubber would during installation into the bar brackets. [email protected]
