Details

Your flathead Ford V8 is how many years old now? And you're thinking about reusing the main cap bolts? Forget it!

Years of service and re-torquing have undoubtedly fatigued your engine's original fasteners, so save yourself some grief by replacing them with new main cap bolts from ARP, the leader in automotive fastener technology. Sold in sets of six, these bolts have special washers and the strength you need to keep that Flathead together for decades to come.

Overall Assessment

The product consistently received positive reviews, with customers commending its high quality and practicality. It's defined by its precise fit, excellent material strength, and smooth, well-cut threads. Buyers have emphasized the bolts' suitability for their engine needs, and a common theme of willingness to repurchase suggests ongoing trust in the product. Its unique features, like the right length and shoulder, differentiate it from competitors. However, a suggestion for improvement is the inclusion of special lube for bolt torquing.

CRANKSHAFT MAIL BEARING BOLTS

These bolts are precisely what the engine is needing. They are the right length, right thread, with the shoulder as it should be. The thread is smooth, well cut, the steel is graded for strength . I would buy the same thing again. Henry would approve.

This bolt set is advertised to fit 32-53. It only fits 49-53. They do not fit 32-48 as the thread reach is incompatible. Plz update your advertising

Main cap bolts for 8ba flathead. Just for added protection, I don't trust 70 year old bolts. Nice that it came with thread lube.
