Engineered and manufactured in Australia, the RD99CE competition Air Locker has been designed around the requirements of top-flight ULTRA4 racing. Each technical advancement addresses a specific concern from teams competing in the worlds toughest 4x4 events and is a direct result of testing within these same races. This Air Locker is for the top-tier racer or the hardcore enthusiast who demands the best equipment for their vehicles. Everyone can benefit from the research and development ARB has committed to the competitive racing circuits. Among the many new design features is an integrated ring gear bolt locking system engineered to prevent the backing out of Ford 9 in. Trac-Loc bolts. Fully reusable and able to resist the high torque loads applied to bolt removal, the locking tabs are designed for disassembly and reassembly for fast pit work on ring gear swaps compared to all other bolt locking systems. Key to the design is the ability to oppose the adverse effects of axle shaft eccentricity caused by typical steering joints,thereby overcoming a common problem with front applications where the differential is offset too far toward one wheel. Achieving new levels of load, wear and impact resistance, the RD99CE case is 290 percent stronger overall compared to standard lockers. Designed with deeper locking engagement, the RD99CE ensures locking functionality is retained even after sustaining significant clutch gear tooth damage from locking under throttle.

Do you offer wholesale or jobber pricing?

Yes. Wholesale pricing is available for legitimate businesses that provide a valid business number or equivalent proof. Ongoing purchase volume is required to maintain discount eligibility. One-time personal buyers aren’t eligible.

Will this part fit my vehicle?

If a product page clearly lists fitment for your vehicle and the description leaves no reasonable doubt, we’ll cover the cost of return if it doesn’t fit. Exclusions apply if prior modifications cause the issue. When browsing self-serve, you’re responsible for confirming compatibility by checking manufacturer fitment data and notes. If unsure, contact us before ordering and we’ll verify it for you.

Do you offer technical support or installation advice?

We help where possible on a case-by-case basis. Most manufacturers include detailed instructions and tech support contacts. Because our catalog spans hundreds of brands, we can’t provide every torque spec or procedure, but we’ll connect you with the manufacturer if needed.

Do you offer price matching?

We don’t guarantee price matching, but we’re happy to review a legitimate in-stock offer from another Canadian retailer. The comparison must include all costs such as product price, shipping, taxes, and fees, and the item must be identical and available for immediate purchase. We won’t lose money to match unsustainable or out-of-stock pricing.

Can I exchange an item?

Yes. In-store exchanges happen on the spot when stock is available. For shipped orders, the original item must be returned first. Once received and inspected, we can issue a store credit toward the correct part or replacement. We can’t send a second item while the first is still in your possession without payment for both.

Are prices shown before or after tax?

All prices on the site are before tax. GST, HST, or PST is calculated at checkout based on your shipping address..
