The Mittler Bros. Rear Hub Kit — 5×5-1/2, 40 Spline, Left Hand is a complete rear hub assembly kit for Grand National floater rear-end applications requiring the wider 5×5-1/2 bolt circle with a 40-spline axle. Every component is included and matched by Mittler Bros. — hub with Timken bearing races and long course studs, bearings, seals, spindle nut with lock ring, drive flange O-ring, steel rotor adapter with all mounting bolts, 40-spline drive flange with bolts, and complete hub cap assembly.
Uses the 8-hole steel rotor adapter plate (SKU 1400-003-S) to mount the brake rotor directly to the hub — no separate brake hat required. Includes the left-hand spindle nut and lock ring (SKU 1400-538). For the right-side kit, see SKU 1400-403-R. For 24-spline versions, see SKU 1400-406-R/L. Made in the USA.
