UMI Performance 08-09 Pontiac G8 10-14 Camaro Trailing Arms

You're looking at UMI Performance trailing arms, designed to bolt right onto your 2008-2009 Pontiac G8 or your 2010-2014 Chevrolet Camaro. These aren't your stock stamped steel arms; they're built from beefy 1-inch by 2-inch rectangular tubing with thick, CNC-machined mounting plates. The main job here is to stiffen up the rear end, cutting down on flex and bushing deflection. This means less of that annoying wheel hop when you get on the gas and a more controlled feeling when you're driving.

UMI assembles these with fluted, greaseable polyurethane bushings. That means you can easily add grease to keep them working smoothly and the fluted design helps hold that grease where it needs to be. The mounting plates are also CNC machined, and the bushing holders are made from DOM tubing for extra strength. They're finished with a durable powder coat to resist rust and look good, and they're made right here in the USA. Installation is straightforward, usually taking less than an hour with basic hand tools, and they use your factory hardware.
