2007 Jeep Wrangler - 426 Hemi JK

Posted in Features on October 1, 2011

Brock Sherwood of Baldwin City, Kansas, is used to working on cool stuff. By day, he is a Department of Defense contractor, maintaining Predator aircraft as an avionics technician. So it’s not surprising that his 2007 Jeep Wrangler Sahara Unlimited JK is a cool looking rig with all the right stuff.

Brock had seen a lot of JK Hemi conversions, but he had yet to see anyone use Mopar’s new 7.0L 426ci Generation III Hemi V-8 crate engine. The 426 Hemi uses an aluminum block and race cam and features a Stage 3 port and polish and an EFO 90mm throttle body. Mated to the 426 is a G56 six-speed manual transmission, which is the same trans used in Dodge Ram 3500 trucks. Aft of the transmission is an Atlas 2SP transfer case with a 4.3:1 low range. The swaps were performed by Kevin Wyas and crew at 4 Wheelers Supply ( in Springfield, Missouri.

Currie RockJock Dana 60 axles sit front and rear and are stuffed with ARB Air Lockers and 4.10 Superior gears. The stout axle combination turns 42x15-17 Pit Bull Rocker bias-ply tires mounted to 17x10 Walker Evans Racing beadlocks with three inches back spacing. To clear the way for the hefty meats Brock had 4 Wheelers Supply install a Rock Krawler 5.5-inch X-Factor Plus three-link suspension system front and rear. A set of 14-inch-travel RRD Racing 2.0 coilover shocks reside up front while a set of 12-inch-travel RRD Racing 2.0 coilover shocks are affixed to the rear. RRD 2.0 hydraulic bump stops are in place to control suspension compression.

Brock isn’t only interested in building 4x4s, he also greatly enjoys using them. He takes to the trails often, attending events such as the Easter Jeep Safari, Jeep Beach 2011, SMORR Show-Me Run, Camp MJ Mid-West, Big Bear Forest Fest, and All-4-Fun. It isn’t just the excitement of ’wheeling that gets him charged up though.

There isn’t much that can stand in the way of Brock Sherwood’s 2007 Jeep Wrangler Sahara Unlimited. Equipped with a HEMI 426 V-8, 42-inch Pit Bull Rocker tires, Rock Krawler coilovers and three-link suspension, and Dana 60 axles front and rear, the rig is wholly capable of tackling obstacles without abandon.

“Being a part of the Jeep community is a big deal,” Brock says. “The community always helps each other out no matter if it is a stock Jeep or built rig. I enjoy helping everyone out, as well. I donated a grand to the BlueRibbon Coalition this year at EJS. It made Del Albright’s week. I’m also on the message boards often, answering questions new Jeep enthusiasts may have.”

To build a 4x4 to this level takes time and patience, but also a bit of help from generous sponsors. Brock represents a number of manufacturers when he ’wheels, including 4WS, Pit Bull Tires, Poison Spyder Customs, Poly Performance, Rigid Industries, Rock Krawler Suspension, and Spiderweb Shades. Take a look at the photos. We think you’ll agree that this JK has all the right stuff.
