Why Upgrade Starter Bolts?

Factory bolts:

• Can loosen over time
• Corrode and weaken
• Lose proper alignment under stress

ARP Fixes That:

• Stainless steel construction – corrosion-resistant and long-lasting
• 12-point head design – better tool access in tight LS engine bays
• Precision-machined threads – accurate fit and torque
• Improved clamping force – keeps starter aligned under load

Translation: no grinding, no slipping, no “why does it sound like that?” moments.
