The Teraflex PRO-LCG suspension system has triangulated upper rear arms that negate the need for a rear track bar. The Teraflex arms are long and the geometry is perfect. Did we mention that Unlimited is one of the best working TJs we've ever driven? The Tom Wood 1350 rear CV driveshaft runs strong and true. A nice touch is the way Tom's crew will polish and clearcoat driveshafts for a very small fee. Stupid for an off-road Jeep? We don't think so and have them do it for every driveshaft they build for us. Mount Logan Off-Road had Alta Muffler in Logan, Utah, install a new cat-back exhaust. This one is clean and really quiets the 4.0L. We don't think loud 4- and 6-cylinder mills sound that great.
