This is a complete front assembled BRX90 portal PHAT™ axle set.
This is a high-performance, heavy-duty axle designed for scale truck project builds. The modular design makes it suitable for different project builds, and the width of the BRX90 axle makes it perfect for any standard 1/10 project rigs.
Packed with many desirable features; a heavy-weighted cast alloy axle housing for low CG, link setup or leaf spring over and under axle setup, chassis-mounted or servo-on-axle setup, front tie-rod or behind-the-axle steering setup, detachable aluminum CNC truss, adjustable caster angle, and more.
It uses top-quality drivetrain components that are heavy-duty and efficient, including a set of heavy-duty steel triangular keyed AR44 axle gears (30/8T) and a pair of BADASS™ steel universal drive shafts for ultimate strength, performance, and durability.
The portal gearbox is designed with four heavy-duty steel gears each for strength and durability. The portal spindle rotates in the same direction as the driveshafts; the axle can fit directly into many standard drivetrain setups without changing the rotational direction of the drivelines.
Includes black color XT diff cover and black color third member unit (fits Reverse AR44 Helical Cut Bevel Gear for running Counter Rotating Center Drive Shafts usually used in the rear axle).
Specification:- Width: 188.3mm / 7.41" pin-to-pin (BRX90 portal front and rear axles have the same widths)

You will need:- For Axle Mounted Servo setup, the optional aluminum servo mount is needed.
- For the Chassis Mounted Servo setup, a panhard link is needed (as almost every car has a different setup, we leave this part up to you).
- For Leaf Spring setup, leaf spring channel may or may not be needed depending on your setup. Leafs can be mounted directly on top and under the axle.
When you receive the axle:
Make sure to grease up the axle set. You can fill up the empty space with diff grease surrounding the bevel gear and input shaft.
The gear positions are factory setup and should be ready to go. Rotate the drivetrain by hand for physical inspection.
Install spacers accordingly between the center driveshaft and the input shaft to prevent input shaft from unnecessary slop.

Great Sunscreen for Kids
Style: SPF 50, Size: 5 Ounce (Pack of 1)
I used this Coppertone Pure and Simple Kids Sunscreen Spray on my kids during a recent beach trip, and I was really impressed. The spray application is super convenient, especially when dealing with active children who won’t stay still. I love that it’s made with zinc oxide and is completely tear-free—no complaints even when it got close to their eyes. It’s mineral-based and gentle on my children’s sensitive skin, with no irritation at all. The SPF 50 provided great protection, and I noticed they didn’t get sunburned even after hours of playing outside. It’s water-resistant, so I didn’t have to reapply constantly after swimming. I also appreciate that it’s free from harsh chemicals and fragrances. The 5 oz size is perfect to throw in a beach bag or backpack. It’s definitely become my go-to sunscreen for outdoor playdates and sports. I highly recommend it to any parent looking for a reliable, kid-friendly sunscreen.

Perfect for Sensitive Skin & So Convenient!
Style: SPF 50, Size: 5 Ounce (Pack of 1)
I absolutely love this sunscreen! The Coppertone Pure and Simple Tear Free Spray SPF 50 has been a lifesaver for my family, especially with little ones who have sensitive skin. It goes on easily, doesn’t irritate their skin or eyes, and provides great sun protection. I love that it’s free of harsh chemicals but still really effective.
I also picked up the sunscreen stick from the same line and it’s amazing for quick touch-ups, especially on the face, ears, and nose. It glides on smoothly without any mess, and it’s super handy to throw in the diaper bag or purse.
Highly recommend both the spray and the stick — a must-have combo for summer!

Difficult to rub in; sweat and water resistant; difficult to wash off
Style: SPF 50, Size: 5 Ounce (Pack of 3)
I've used this spray sunscreen off and on for the past two years and have now decided to only use it after a long and sweaty work out at the gym when I drive home. It is much easier to apply onto the skin on sweaty/wet/moist skin than on dry skin.
It is difficult to apply and rub in on dry skin. One should carefully apply and use a finger to do so to minimize stretching the skin. The positive about this sunscreen is that it is sweat resistant and will not seep or run into your eyes. It is also water resistant; therefore, it is a good sunscreen to use if you are going swimming. However, this makes it difficult to wash off, even in the shower using a face wash or scrub.
I would not recommend this sunscreen for daily use. If you are wearing sunscreen for the purposes of avoiding incidental sun exposure, such as driving to and from places, locally, for fewer than 20-30 minutes, or if you are going for brief walks outside, use a different sunscreen that is friendlier on the skin.
I WOULD recommend this sunscreen to anyone that plans on spending prolonged periods of time out in the sun, including being exposed to direct sunlight. If you are planning a day out at the beach, or going out swimming, exercising outdoors for over 30 minutes, taking a long road trip, or planning to do any activity where you will be in direct sunlight, this is a good sunscreen to use. It will leave a white cast, however, I have confidence that it will provide the adequate protection against UVA-1, UVA-2 and UVB radiation to protect your skin.

Good sunscreen
Style: SPF 50, Size: 5 Ounce (Pack of 1)
Great alternative to chemical sunscreen, spray is a little patchy and leaves a heavy white residue but that is to be expected. Works well and prevents sunburn so it's a win.
