The ultra-wide 270mm hanger length lets you to run up to dual 6396 motors with 15mm belts, with plenty of room to spare. The hanger shares a similar cross section profile to Caliber II, meaning all Caliber II mounts on the market fit this hanger. When bought with our mounts, we automatically include a precision clamp made specifically for our hanger.
A long hanger calls for strong axles. We went for 10mm to 8mm stepped axles which gives the best of both worlds; the strength of 10mm axle with the bearing compatibility of 8mm axles. Machined from heat treated 17-4 stainless steel and held to a tighter tolerance than shoulder bolts and traditional skate axles. The extended length alloys for easy installation of bearing pulleys without running out of axle.
I’m not so sure that being wider is inherently more or less stable. Surely, the width of hanger will impact turn radius. Taking that into consideration. It may be more difficult to recover from a wobble on a less responsive truck.
Not sure how this would change press-fit mounting. They rely on axial force to keep the retainer locked in. These can provide that the same way shoulder bolts can so from what I can tell, they work the same way.
Edit: I see what you mean. These will still work, but take some playing around with the spacers.
