Perfect Pass 7075 Aluminum Bulkhead – Complete Performance Kit for ARRMA 6S / 1/7

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 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.

Perfected Sway-Bar System

  • 7075 Sway-Bar Covers: Precision aluminum sway-bar clamps for 2.4mm (front), 2.7mm (rear), and 4mm “Monster” sway-bar upgrade.
  • Direct Factory Fit: Installs with no modification – designed to align perfectly with ARRMA 6S / 1/7 chassis geometry.

Performance You Can Feel

Every dimension of this bulkhead has been refined for perfect gear alignment, zero drivetrain flex, and flawless bearing support. From the sealed design to the micrometer-grade machining, this is the ultimate structural upgrade for high-power ARRMA builds and 200 mph+ speed runs, Drag and Bashing!

Love them more than the stock exb bulkheads. They have a little more room to precisely shim the diffs. They are also comes with all the hardware that you need. Like: shims, bearings, stainless steel screws and good quality rubber gasket. I installed a set on my new talion exb and it turned out so great. Super smooth, no weird noises. It was worth an upgrade for me even though my trucks already comes with exb bulkheads

Very precise fit. I was a machinist for 42 years. The quality of the machine work and fit and finish is second to none. This product went together with no problems. The pinion and side gear shims allow for a perfect ring and pinion mesh. The housing strength is far superior to the original plastic differential housing. We tested my infraction 6s today after installing everything. It is so smooth now and very quiet! Raz thank you for the quality of parts and the dedication to our sport. You wont find a better product out there. Worth every penny imo..

As all my previous orders, these bulkheads are perfect. Nice and tight bearing tolerances. Easy to make adjustments with provided shims. Only problem is I should have ordered another set.
