I'm happy with my ifs.. There are many options out there to improve it. But my rig is a daily driver and I only wheel a few times a month which is why SAS'ing is out of the question. I'm realy impressed with how it performs off road and how well everything parts-wise has held up.
What have I put into my IFS? 1.5" BJ spacers, Moog Idler & Pitman arm, ball joints, new CV boots, and a Downey IFS brace. Everything for around 300 bucks and I can wheel the hell out of it without worrying too much about failure.
