Its easy to assemble a show-quality engine when you use ARPs handy Engine & Accessory Fastener Set. Virtually everything you need comes completely organized in one convenient package (no need to deal with twelve different part numbers)! More importan tly each and every fastener is superior in strength to the OEM bolts and also significantly better than hardware grades (even Grade 8). You have a choice of two premium quality materials and finishes. Traditionalists will appreciate the strength and fun ctionality of ARPs heat-treated 8740 Chrome Moly steel alloy bolts which feature a black oxide finish.
