I have had RC adj arms for over 4 years and replaced one bushing for 15 bucks about 8 months ago. I have been happy with them. That is the only RC component I have had so I can't give you an opinion on anything else they sell.
BUT I wouldn't go over 2.5 susp lift unless you are prepared to spend more money and time understanding the extra that could go along with it.
