Kartek Off-Road Rebuildable 33 Spline Midboard Micro Stub Bearing Assembly For 3.90" Trailing Arms

Our American made, race proven, hub bearing assemblies are fully serviceable. You can purchase replacement bearings, seals and crush sleeves. They fit a 3.90" (3-7/8") MID-BOARD trailing arm plate and use ten 7/16"-14 coarse thread bolts for the brake hub. Three 14mm 1.5 thread bolts hold the hub bearing to your trailing arm plate.

They can be used as a replacement for Jamar Performance or PME's MID-BOARD Porsche 930 or Porsche 934 micro stub brake kits.

Important Information:

Do NOT have your buggy on the ground before torquing each nut and bolt to specification

After 5 miles of testing, retorque all nuts and bolts because the bearing assembly will "settle"

The bearing assembly DOES NOT come greased. You'll need to purchase grease.
