We compare the Boom Racing BRX90 axle to the Boom Racing Scale Phat axle V2

Comparing the BRX90 to the scale v2 Phat axle. The BRX90 axle is a upgrade over the scale Phat axle and this video shows the difference. I do like Boom Racing stuff and I love that they offer quality products at a nice price and give budget opinions like the axles in this video.

Just broke my front Yota 2 axle shaft, 3 total hours of run time, replacement parts no where to be found. Based on your recommendations a set of BRX90s are on their way! Thank you!!

Thank you for your time. This video is the one that got me to purchase a set of BRX 90s a quick question. My pinion angle keeps changing especially on the front axle. I’m running leaf springs but I’m also running longer bolts with locknuts. I don’t think it’s gotten to the point to where the splines have worn but I’m not sure exactly how to tie dye need to make these, so they won’t spin.

Hello Jeremy, Are you on Facebook by chance?

[@RCsBigAir]

Very good thorough comparison. Can tell you really know what your talking about. I thought they both looked good but it was good to hear you explain the differences.

Great information and video

The Boom axles are extremely strong. Jason tested(as in beat the snot out of) the Badass Axles along with the LC70 2-speed with high kv brushless on 4s. I seen videos. He really wanted something that wouldn't have problems. I believe they are way stronger than Axial stuff. Stainless(regardless of hardness of the medal) should never be used in anything that see twisting forces. I run the BRX70's on my Trailfinder's then for the extra width I use the 90's conversion. That way I can tuck-in the dually's when i want a one-ton look. Oh...the high-pinion on the BRX70'S and 90's give the rig a much better driveshaft angle....and the extra steering and gear choices over the Trailfinder axles is awesome. Awesome video as always.

[@axletwisterrc4526]

I definitely agree. I also agree with the stainless. Alot of people think stainless is better but drivelines is definitely not the place for it. The stainless boom used is comparable I would say to the stock yota2 axle quality so I couldn't knock it that bad lol. As always thanks for watching my friend. I always appreciate your feedback and info.

Do you by any chance know the link length from the knuckle to the servo to run those BRX90's on a TF2? Thanks!

[@seansrcconstruction]

Pretty cool comparison. How’s the camel rig coming along?

[@axletwisterrc4526]

Lol not moving much at all. The chassis is almost done but the body is just killing me lol.

[@joang878]

For the scale phat v2 whats the size of the sealed bearing? And you have idea if possible to flip the ring gear on the rear axle planning to use reverse rotation. And on the front axle is there a overdrive gear for that scale phat v2 axle? Ar44 overdrive is possible to use? Please advise. Nice head to head review of boomracing axles👌

[@axletwisterrc4526]

I will have a video out shortly answering all your questions. You beat me to it lol. We are going to get extremely deep with axle info on it😉. Thanks for watching!

[@axletwisterrc4526]

The sealed bearing in the video is 5x11. What axle are you wanting to know about flipping the rotation on? The V2 does not have a overdrive option. On the BRX90 axle all options for the AR44 so you can definitely overdrive it. Sorry I wanted to have my video out by now but time hasn't allowed. I wanted to get back with this info so you had it.

[@redpeppersrc8599]

Would Yota 2 shafts and diff gears work with this axle?

[@axletwisterrc4526]

Sorry I missed your comment. No they will not work.

[@supersnoopy73]

What is the difference between the brx70s and 90s. Great information on thiese axles too thanks

[@axletwisterrc4526]

BRX70 axles are just more narrow than the BRX90. With that said the axle shafts are shorter in the BRX70 than the 90s so they are not interchangeable. They both use the same AR44 ring and pinion.

[@trevorcourt1403]

What size bearings do I need to upgrade to sealed bearings in axle

[@axletwisterrc4526]

Sorry for the delay I missed your comment. The smaller bearings are 5x10 if I remember correctly. Sorry I sold the axles so I cant double check them.

[@markpruitt5384]

Can I pair the BRX 90s with any portals?

[@axletwisterrc4526]

No BRX axles have a different setup all together and the best of my knowledge has no portals that will bolt directly to them.

[@CodytheFordGuy]

are these the axles you run on your tf2? Thanks!

[@axletwisterrc4526]

Nope I run AR44 axles. The BRX90 axles are a nice option also.
