OEM Toyota Cylinder Head Bolt Set
When removing or replacing a cylinder head, installing fresh head bolts is critical to ensuring long-term engine reliability. Because factory cylinder head bolts undergo extreme tensile stress during initial torqueing, reusing stretched hardware can lead to improper clamping force or fastener failure. Toyota design specifications classify the stock head bolts for 20R, 22R, and 22RE engines as single-use components. Restore factory-spec sealing performance with this genuine, affordable OEM replacement set.
