BMT 701 +1 steering block inserts
Coming from BMT and made for the 701 kit are the +1 steering block inserts. Machined from aluminium and coming with a natural finish the insets allow to adjust the king pin angle which can be a useful tuning option in certain track conditions. Depending on the orientation the king pin angle can be increased or decreased by simply flipping the inserts.
