Replacement Inserts - Solid Front Control Arm Mounts - E30 & E36 (Treehouse TrackCAB)

Two Heavy-Duty replacement UHMW inserts for our Solid Front Control Arm Mounts. They also work with the NLA Treehouse E36 & E30 Eyeball Arms. UHMW is the best material for these inserts. We do not use Delrin as it is not self-lubricating and can squeak, crack and degrade over time.
