The Currie brothers, owners of Currie Enterprises, have always owned great 4x4 vehicles. As technology changes, the Curries have always stepped up and built the next latest and greatest. When Jeep introduced the new JK Wrangler, it wasn't long before John Currie and the Currie engineering staff had a JK Unlimited that not only works as well off-road as all former Currie vehicles but also cruises getting to the trail and back on the highway.
The Iron Jock 60 frontend with Rubicon knuckles and disc brakes has hardened 35-spline inner and 32-spline outer axles, CTM U-joints, 5.38 gears, and a Detroit Locker. These are stock width and run JK 5x5 lug pattern wheels. You can see Currie's drag-link bracket. There's an adjustable drag link behind the PSC ram hoses. Also note the Currie towbar attachment brackets and the RockJock skidplate.
This red cruiser started as an '07 Jeep JK Wrangler Unlimited Rubicon (whew - vehicle names keep getting longer). It has the 3.8 V6 that comes in all JKs and an overdrive automatic transmission. The Rock-Trac Rubicon transfer case with 4:1 Low range was retained since it's so strong and works well. J.E. Reel driveshafts carry the power to the frontends and rearends.
Currie Enterprises started business building Ford 9-inch rearends and are still the 9-inch leaders with their 9-Plus series. Many years ago, the Curries branched out and started offering other frontends and rearends, as well as Jeep parts and accessories. Today, the Currie RockJock line includes everything from axles to armor. The Currie Cruiser features the new Currie Iron Jock 60 frontend that uses JK Rubicon knuckles, has hardened 35-spline inner axles and 32-spline outers, CTM joints, 5.38 gears, and a Detroit Locker. The Iron Jock 60 rearend has 35-spline axles, 5.38 gears, and an ARB Air Locker. The Wrangler retains the JK's 5x5 lug pattern. The 5.38 gears sound low, but the high-revving 3.8 V6 likes them, especially with 37-inch tires mounted.
The Iron Jock 60 is a high-pinion design. The Currie RockJock JK suspension has adjustable control arms that install in the factory position and are adjustable for easy caster- and pinion-angle adjustment. | 
The J.E. Reel CV driveshafts are strong and true. The little skidplate under the third member works well, allowing rocks to slide right under. | 
The RockJock JK suspension features progressive coil springs, Antirock swaybars front and rear, and optional Walker Evans Racing reservoir shocks. |

The rear Iron Jock 60 has hardened 35-spline axles, 5.38 gears, and an ARB Air Locker. The Walker Evans Racing 2.0 adjustable reservoir shocks have 14 compression adjustments available. The adjustable front and rear track bars have a new smaller Johnny Joint specially designed for track-bar use. Currie Enterprises is working on a JK exhaust system, but the muffler will probably be located in the stock position, not on the driver side as this one is. |
