I enjoy a bit of spirited driving and the body roll on my stock truck deminished that enjoyment. I couldn't find a lot of information about adding a rear sway bar, so I just took the plunge. I bought a Hellwig rear sway bar kit from Summit Racing and bolted it up. This was a very nice mod and I would recomend it. It cost less than $150 and took around 2 hours to install. Hellwig also makes a heavier front sway bar. Pricier sway bar kits are also available from Hotchkis.
