ShiftKnob for 10th Gen Civics by Alta Performance The ALTA Shift Knob has a 1.85\” diameter and weighs approximately a half pound! This is 4.5 ounces heavier than the OEM knob! By adding weight to the knob, it gives each shift an entirely more positive feel! The larger profile feels great in your hand and allows more of your hand to engage with the knob. The ALTA Shift Knob\’s height range can be adjusted by nearly 1 inch with the built-in adjustment screw. Once the height is set, tighten the lock bolt and your knob will never loosen on its own. The entire process takes less than a minute! Best of all, our super locking mechanism will not harm the threads of your OEM shifter rod! The ALTA Shift Knob is precision machined and left raw with a brushed finish over the stainless steel. The combination of construction and finish gives the ALTA Shift Knob a durable and attractive appearance for years to come. Our multi-piece design eases installation and looks great! The main body is precision machined from heavyweight stainless steel. Gear changes with our stainless steel shift knob have been best likened to a bolt-action rifle! The lower piece is machined from billet aluminum and designed to hold your shift boot up with its lower groove.
