- LEGO® Technic — about the system
LEGO®'s own primer on the Technic system — gears, axles, pins and the functions they build. A plain-language starting point for a first working drivetrain.
- LEGO® Technic (official)
The official Technic theme — the flagship sets with functioning gearboxes, driven axles and working suspension. Where most fake-motion engines and drivetrains ship.
- Technic Gear Differential Housing (part 65414)
A modern Technic differential housing — the part that splits drive between two wheels and lets them turn at different speeds. Look up part 65414 and its fitment.
What counts as Engine & Drivetrain on Bricks & Octane?
Fake-motion engines, gearboxes, diffs, suspension and steering — the working machinery. In the Speed Shop it covers Engine blocks, Forced induction, Exhausts, Gearboxes, Differentials, Drivetrain layout (RWD / FWD / AWD), Suspension, Steering and Ground clearance & ride height.
Are these official LEGO® parts or third-party aftermarket ones?
Both, and each is labelled. Official LEGO® elements link straight out to BrickLink or Rebrickable, which own the parts database and do it better; third-party add-ons are clearly marked aftermarket, never as official LEGO® products. Bricks & Octane sells nothing and rehosts nothing — every entry is a deep link to its source.
Where do the Engine & Drivetrain builds, videos and builders come from?
They are pages already published on Bricks & Octane — fan MOCs and official-set builds, community videos and builder profiles — matched to this family by its own search vocabulary (gearbox, transmission, v8 engine). Each one opens its page here, which links out to the creator's original; we never rehost a builder's images or instructions.
