Atomic Billet Oil Pump Gears

Gas Nitrided for Ultimate Toughness

Why You Should Upgrade Your Oil Pump Gears

The factory Ford Barra oil pump gears are made from sintered iron—a process of compressing metal powder. While fine for a stock commuter car, this material is brittle and notoriously weak under shock loading. High RPM limiters, aggressive launch control, and torsional crank harmonics can shatter these gears instantly, causing immediate loss of oil pressure and catastrophic engine failure.

💡 DID YOU KNOW?

"Limiter Bashing" is the #1 killer of oil pumps. The sudden harmonic shock sent through the crankshaft when hitting a hard rev limiter acts like a hammer blow to the oil pump gears. Billet gears absorb this shock; factory sintered gears shatter like glass.

The Atomic Solution

We engineered the ultimate insurance policy for your engine. Our gears are precision CNC machined from 4340 Billet Steel, offering vastly superior tensile strength and ductility compared to the OEM sintered part. But we didn't stop there—we now Gas Nitride every gear set. This advanced heat treatment penetrates the surface to increase hardness and wear resistance while maintaining a tough, shock-resistant core.

Billet Steel Strength. Gas Nitrided Finish.
Precision machined tolerances for optimal oil pressure.

2. Precision Gerotor Design

Strength means nothing without pressure. Our gears are machined to exact gerotor profiles to ensure consistent volumetric efficiency.

  • Gas Nitriding: Provides a hard, low-friction surface finish that resists scoring and wear against the housing, extending the life of the pump.
  • Precision Tolerances: Machined to strict tolerances to ensure proper inner-to-outer gear clearance, maximizing oil pressure at hot idle.
  • Direct Replacement: Designed to fit directly into your existing factory oil pump housing (housing condition must be verified).

Treatment: Gas Nitrided

Application: Ford Barra DOHC 4.0L

⚠️ Critical Install Notes

  • Check Housing Clearance: You MUST measure the clearance between the new gears and your oil pump housing. Worn housings will result in low oil pressure.
  • Priming is Essential: Never start a fresh engine without priming the oil pump first. Pack the pump with petroleum jelly (Vaseline) or assembly lube to ensure it creates suction immediately on startup.
  • Inspection: Always inspect the backing plate for wear. We recommend using our Billet Steel Backing Plate for the ultimate setup.

Super Cute, Fun, & Effective
Color: Lightgreen
This set of water flosser and electric toothbrush are just adorable! The shapes of them fit in the hands really comfortably, but also add to the cuteness as the shapes of the animals! Yes, this is meant for kids - so the toothbrush heads are small (for little kids), and the water flosser doesn't spray terribly hard. BUT they're still very effective. I especially like the water flosser. It can be taken into the bathtub/shower while bathing, so the spray doesn't end up going places we don't want water to go. It has a small tank of water, and I recommend using room temp water (rather than cold) so that it's comfortable on the gums and teeth. Also to note, the flosser doesn't work when it's sideways or upside-down - it needs to be held upright. This set is so cute, easy to use, easy to re-charge, and very comfortable. It's also very good quality - a great purchase. I love it!

4 year old approved!
Color: Lightgreen, Color: Lightgreen
Love that this is a complete set, down to the wall block for the charger! My daughter is 4 and absolutely loves this set. I personally feel like the toothbrush head is a tad small, but it does do the job well. Its a soft brush head, with plenty of replacement heads. The toothbrush and the flosser both arrived fully charged, and so far we havent had to recharge it, but we're only a few days in. So, it seems to have a pretty good battery life so far. (I will update my review if anything changes on that aspect) The toothbrush and flosser both stand upright independently on the counter, without tipping over. The water flosser is hard fir my daughter to do by herself. She sprays water everywhere, as theres several buttons on it and she cant seem to remember in time which button turns it off. I help her with flossing and its been going fine. Whether youre on high or low the water pressure is not too hard for a kids mouth. In fact, I think the low setting does nothing but rinse the mouth and basically teach the habit of flossing. We use the high setting and it does and OK job. I am a little old school though, and feel like nothing will top a good ole dental floss flossing, but water flossing is a safer route to avoid cutting gums or getting floss stuck between close teeth. The sound level is minimal, a fraction of the sound level my adult water flosser makes. It doesnt shake/vibrate too badly in the hand and theyre bith comfortable to hold, and size appropriate for my (4yrs) daughters hands. It comes in a really nice box, packaged perfectly, making this a great gift for your little ones. The colors and theme makes brushing teeth exciting and fun again for your littles :)

Great for kids
Color: Lightgreen
The HUACOCARE Kids Water Flosser and Electric Toothbrush Combo is an absolute game-changer for establishing a solid dental hygiene routine with children. The light green giraffe and monkey design is incredibly charming and immediately turned what used to be a bedtime struggle into a fun activity that my child actually looks forward to. Having both the sonic toothbrush and the water flosser in one compact unit is brilliant, as it saves counter space while ensuring that every part of their mouth gets a professional-level clean. The three gentle flossing modes and two sonic brushing modes are perfectly calibrated for younger, more sensitive gums, providing a thorough clean without any discomfort. One of the standout features of this set is how braces-friendly it is; the water flosser reaches those tricky spots around wires and brackets that a standard toothbrush simply can't touch. It is clear that a lot of thought went into the ergonomics and the "fun factor," making it a perfect gift that is both practical and engaging. Since we started using this combo, our dentist has noticed a significant improvement in plaque removal and overall gum health. If you are looking for an all-in-one solution to build healthy brushing habits and make dental care feel like less of a chore, this set is worth every penny.

⭐️⭐️⭐️⭐️⭐️ Five-Star Review: Burst Kids Unicorn Water Flosser
Style: Unicorn
We absolutely love the Burst Kids Unicorn Water Flosser! The design is adorable and instantly made my child excited about flossing, which is half the battle. Quality: The build feels sturdy and well-made, definitely not a flimsy toy. Water Capacity: The reservoir holds plenty of water for a full clean without needing constant refills. Gum Health: We’ve noticed healthier gums and less sensitivity since using it regularly, it’s gentle but very effective. Ease of Use: Super easy for kids to handle on their own, with simple buttons and a comfortable grip. Functionality: Multiple settings work great for different comfort levels, and it does an excellent job cleaning between teeth and along the gum line. Overall, this flosser has made oral hygiene fun and stress-free. Highly recommend for any parent looking to improve their child’s dental routine! 🦄✨
