Spindle Pin/Sleeve Set (Revised Short/Long Eb/NB48 2.1)

These revised sleeves are required when using the TKR9141B -2mm spindles with CVA's and have been modified from the stock TKR9057 sleeves to provide clearance for the 15x21x4mm bearings. However, if you are running UNI's, the standard TKR9057 will work just fine. They are a direct replacement for TKR9057 going forward and are compatible with TKR9141 standard height spindles. Recommended to use with: TKR9141B - Adjustable Ackerman Spindles (-2mm, EB/NB 2.1, requires TKR9057B)
