FAQ
Is 54597 the driver-side gasket?Yes. 54597 is the left (driver) side. The companion right (passenger) side is part number 54598.
What’s the benefit of the Wave-Stopper design?Concentric waves in the active steel layer help the gasket adapt to varying loads and pressures for improved sealing stability over time.
Do I need studs or are new bolts okay?Fresh torque-to-yield bolts are acceptable on stock power. For tuned/boosted builds, head studs are strongly recommended.
Which thickness do I choose?This listing is Grade C (≈1.05 mm). Use your measured piston protrusion and machine work results to select the correct grade.
