Description

SET Group USA

Overview

5x4.75 to 6x5.5 wheel adapters in 2" (50mm), sold as a 4 piece set. Machined from forged 6061 T-6 aerospace grade aluminum and hard anodized for corrosion resistance. This is a two piece adapter. The first plate bolts to the vehicle hub on its existing studs and carries a 74mm bore. The second plate fastens to the first with allen head screws and carries the new studs for the wheel. The two bores differ because each plate is sized to its own bolt pattern. Neither plate has a wheel centering lip, so this adapter is lug centric.

What's in the set
  • 4 x 2" (50mm) wheel adapter, pressed 12x1.5 studs
  • 20 x 12x1.5 lug nuts
  • Converts a 5x4.75 vehicle to 6x5.5 wheels
  • 74mm center bore
Fitment
  • Fits any 5x4.75 (5x120.65) vehicle with 12x1.5 studs
  • Chevrolet, Buick, Pontiac, Oldsmobile and GMC classic and mid-size applications
  • Lug centric on a universal clearance bore - the included lug nuts centre the part, not a hub lip. Confirm your stud thread matches before ordering.

Confirm your bolt pattern, hub bore and stud thread before ordering.

Important information

Torque to your vehicle manufacturer's specification and re-torque after the first 50 to 100 miles. Wheel studs must engage a minimum of the stud diameter in thread. Installation by a qualified technician is recommended.
