These bushings fit stock 8.3 tekno BLOCKS. made using Delrin material. These bushings have proven to last much longer than the
stock injected bushings . These bushings are made to be used with our tapered hinge pins and will not work with the stock pins.
Due to the design of these inserts and hinge pins, this system is designed for the hinge pin and arm to rotate in the bushing.
Therefore if you bend a hinge pin it will not effect the movement of the arm.
Bushings are sold in pks of 4 so you can choose only the bushings that suite your needs.
THESE BUSHING ARE DESIGNED TO BE USED WITH THE M2C 6737 TAPERED HINGE PINS.
If used on SCT models you will have to trim the rear bumper for clearence of insert.
