Product Details

The ARP 134-5202 High Performance Series main bolt kit is engineered for Chevrolet small block engines with large journal crankshafts and 4-bolt main caps. These premium fasteners provide superior clamping force and reliability for high-performance and racing applications where stock hardware simply isn't adequate.

Key Features:

  • Chrome moly steel construction for exceptional strength and durability
  • Heat-treated to 200,000 PSI tensile strength for maximum clamping force
  • Hex head design for positive engagement and accurate torque application
  • Includes hardened washers for proper load distribution
  • Thread rolled after heat treatment to prevent fatigue failure
  • Black oxide finish for corrosion resistance

Application:

  • Chevrolet small block V8 engines with large journal (2.45" diameter) crankshafts
  • 4-bolt main cap configurations only

ARP main bolts are a critical upgrade for any performance engine build, providing the foundation for increased power output and enhanced reliability. Each fastener is precision-machined to exacting tolerances and features ARP's proprietary thread design for consistent torque loading. The included washers ensure even load distribution across the main cap surface, preventing cap distortion and ensuring proper bearing alignment.

QUICK!!!! THANKS-

I am completely satisfied with this shopping experience

Found what I was looking for at a go price, especially like free shipping.

So far so good, and fairly easy to navigate?

I was very pleased with my transaction with Autoplicity. My order was shipped the next day and received the following day. The pricing was also the best I could find. I would definitely buy from them again and recommend them to others.

Shipment was quicker than I thought and the product was just as described. It was cheaper than else where. Thank you Autoplicity

Lowest prices on name brand items, quick shipping, and provide information on the status of your order.

Autoplicity had the best price for my Thule 867 roof rack cargo bag. It was easy to pay thru my Amazon accont and the order shipped within 24 hours of my placing the order.
