The Perfect Pass RC 7075 Aluminum Bulkhead is engineered for drivers who demand absolute precision, durability, and reliability. Designed for ARRMA 6S and 1/7-scale platforms including the Limitless, Infraction, and Felony, this is the strongest and most complete bulkhead kit ever offered.
Unmatched Precision & Strength
- 7075-T6 Billet Aluminum: CNC-machined from aerospace-grade 7075-T6 for maximum rigidity and impact resistance.
- Press-Fit NSK Bearings: Genuine Japanese NSK bearings are interference-fitted (not loose) to eliminate bearing spin and prevent housing wear.
- Water & Debris Seal: A bottom seal keeps dust, moisture, and dirt out of the bulkhead for long-term reliability.
All-Inclusive Hardware Kit
- Stainless Steel Screws: Complete stainless hardware set included — rust-proof and race-ready.
- Dual Input Shaft Bearings: Comes with both 5 mm and 8 mm 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.
Perfected Sway-Bar System
- 7075 Sway-Bar Covers: Precision aluminum sway-bar clamps for 2.4 mm (front), 2.7 mm (rear), and 4 mm “Monster” sway-bar upgrade.
- Direct Factory Fit: Installs with no modification — designed to align perfectly with ARRMA 6S / 1/7 chassis geometry.

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.
