TeraFlex manufactures components for the Jeep Wrangler including premium suspension systems and performance shocks, heavy-duty axles and low-range gearing, body armor, and more. With our roots dating back to the 1950s beginning as MEPCO (Military Equipment Parts Company), a distributor of Jeep parts and accessories, we have gained a vast knowledge of the various CJ/Wrangler platforms.

In the fall of 1996, TeraFlex began manufacturing parts in-house to fulfill the need for heavy-duty off-road suspension pieces and equipment for the then-new TJ Wrangler. Our experience and knowledge has allowed us to create the unique and innovative parts and accessories that fill out our product line today ensuring TeraFlex’s dominant hold on the Jeep market.

Not only was TeraFlex the first manufacturer to engineer a suspension system for the TJ Wrangler’s all-new coil spring suspension, but we are the only aftermarket company to offer a solution for the venerable 231 transfer case’s low-range gearing. Then in 2001, TeraFlex stunned the entire off-road industry with the TJ’s CRD60 – an off-road specific high-pinion differential based around the Dana 60 axle platform. The CRD60 took innovation to a new level, reinforcing our position in the industry.

TeraFlex continues its stronghold on the Jeep market offering the most comprehensive lineup of performance components for the JK Wrangler and JKU Wrangler Unlimited compared to any other competitor to date.

ARB Air Lockers now come with an Industry leading 5 Year Warranty

Never satisfied with the achievements of yesterday, ARB has remained focussed on evolving the Air Locker design into an even more superior product. As a result, ARB is celebrating 25 years of innovation with new features such as forged gears, timed gearing and a two piece design, along with launching a new logo and industry leading 5 year warranty.
Forged gears, which deliver increased load carrying capacity and strength, are typically found in the most demanding applications, including heavy duty industrial, commercial, race car and agricultural transmissions. In the Air Locker, the phenomenal amount of force applied to the gears means that their strength, durability and fatigue resistance is paramount, and so forged gears have been implemented across the range.
When combined with ARB’s patented ‘timed gear’ design, the resulting strength of the whole assembly is amplified. Simply put, timing the gears ensures that no matter when the Air Locker is activated, the gear teeth will always ‘lock’ into predetermined positions that offer the greatest surface area between the gear teeth. This ensures that optimal locking strength is achieved every time the Air Locker is activated.

Housing this superior internal gear train in a two piece case brings further benefits. Machining a case from two pieces instead of three results in a much higher dimensional accuracy of the finished assembly. Eliminating the smaller cylinder cap as a separate part and switching the air entry to the crown wheel side of the differential not only adds huge strength, but also allows ARB to refine the locking mechanism design, eliminate the need for an internal annular piston, and lock the side gear directly to a redesigned high strength flange cap. In addition, this also allows the locking ring to reside closer to the splined side gear, considerably reducing actuation and disengagement time.
ARB’s Air Locker division, based in Melbourne, utilises the latest arsenal of software programs, including Solidworks, CAD and Cosmos, in the development of all Air Lockers. The lengthy design process involves countless hours of testing using Finite Element Analysis (FEA), which allows the engineers to subject each Air Locker design to ‘virtual’ off road driving simulations which are impossible to replicate in the real world.
Prototypes are then fitted to 4WDs that operate in the harshest environments imaginable, including Outback NSW, the Flinders Ranges and Victorian High Country. Some prototypes are sent internationally to be put through their paces in extreme off road racing events like the iconic King of the Hammers in the Southern California desert.
ARB Air Lockers are all manufactured in a world class, aerospace standard machine shop in Melbourne. Utilising aerospace grade materials and state of the art machinery, the facility ensures that the Air Locker maintains its reputation for quality, durability and reliability throughout the world. Backed by an industry leading five year warranty, the Air Locker is available for an extensive range of vehicle models, with over 100 applications.
