- Dual Input Shaft Bearings: Comes with both 5mm and 8mm input bearings for full compatibility with any setup.
- Precision Shims: Includes side shims and center input-shaft shims so you can fine-tune your ring-gear mesh to perfection.

- 7075 Sway-Bar Covers: Precision aluminum sway-bar clamps for 2.4mm (front), 2.7mm (rear), and 4mm “Monster” sway-bar upgrade.

This 7075 aluminum bulkhead receives outstanding reviews, with customers praising its "perfect fit" and exceptional tolerances. Shoppers said it reduces drivetrain friction and prevents bearing housing warping. One noted "zero play without binding" with .0005" movement. Includes NSK bearings and hardware. One customer was disappointed expecting both front/rear.
Perfect fit
Perfect fit very happy
Best in the buisness
You might be able to find slightly cheaper but not better. Comes with all the hardware. Bearings. Toolbar mountings. The whole lot and fits like a glove
Absolutely flawless. The best bulkheads on the market!!!
No more warping of the bearing housing and less drivetrain friction means less amps pulled.
Better than the original that comes in any of the Arrma 7 scales.
Construction of piece is spot on, fit better then the original. Keep up the great work...
Another great product from Perfect Pass
Beautiful Parts
Very nice everything is perfect
Hands down the best diff housing out there. Not only does it look amazing, but the fitment is the best that I've seen... the tolerances are perfect making everything fit like a glove. Get yours... you will not be disappointed!
Great product
Well packaged, quality parts and most importantly fast shipping! Majority of my build is from Perfect Pass!! Keep on the great quality work!
Quality is top tier! Absolutely love these parts and how thought out they are!
Fit just as advertised. Snug fit basically no play in the gears of bearings. I would buy again.
Very good fit nice and shiny should last a lifetime
I have not had a chance to run these yet as I am in the middle of the build waiting on parts. But I will say that the fit of the bearings is exceptional. Zero play without having to press them in. I was able for the first time to setup a bulkhead with zero play and zero binding. Well, if i put an indicator on the diff, the back and forth movement is .0005 thou. Never been able to dial it in like that. Nice job Raz!
Beautiful chrome bulkhead craftsmanship. Everything fit perfect. PP ships fast and has top notch products. I will be buying many more parts for walk of my rc cards/trucks. Thank you ras and team.
Look is amazing and the fit was even better. Didn’t expect anything else from Pefect Pass.
Absolutely love these bulkheads fit is exactly perfect. Top quality no question.
It's a great product great quality as always can't wait to get this build all together and see what she can do
Best bulkhead period. I had to add one shim for a perfect alignment. Everything fits tightly. It’s also ready for the 4MM sway bars. It contains all of the hardware you will need for installation.
Beautiful product :)
Very good quality....... But I thought I was getting both front and back because of the picture. So I thought it was a great deal but now there sold out and I have to wait for my next one to be available. That was disappointing.
Beautiful product
Stunning, chrome bulkheads. If they perform as good as they look, we got another no brainer from Perfect Pass. I haven't installed them yet, but I'll update if I have any issues.
Do These work in the notorious V6? Sorry I know I asked before but I can’t find the response in my emails.
Hey,
No, the bulkheads are not compatible with the notorious.
