These new tower a-frame mounts are slotted and inset to accept different position keys allowing for simple upper a-frame adjustment. Tower mounts are also available as a new option for “SS” and “ES” style front frames providing an alternative to the “M” style double shear a-frame mounts. The shim plates are used for adjusting the spacing of the a-frames.

Note: Keys are interchangable with Blue Max a-frame Keys.
