Our custom-made ARP Main Stud Kit for Volvo S60R and V70R are simply the best stud setup availalbe in the market today. They are manufactured using premium quality ARP 2000 material. Our ARP Main Stud Kit is meant to replace the original Volvo Intermediate to Cylinder Block Bolts 

Manufacturing Process

ARP uses a premium quality ARP 2000 material that is rated superior to aircraft quality. Each stud is placed vertically in special racks and heat-treated to ensure 360° penetration. This procedure is far superior to other methods of dumping items in a large bin and batch treating.

Following heat-treatment, each stud is shot-peened to remove surface irregularities, and then undergoes a centerless grinding process to ensure they are perfectly concentric. This procedure involves about ten machining steps for an exceptionally straight part.

The studs are then thread rolled after heat-treatment, which gives them about 1000% (10 times) more fatigue strength than those studs that are threaded prior to heat-treatment.

ARP Nuts are manufactured in a multi-step process that “blanks” the hex and 12-point nuts and is followed by a CNC-threading process which taps each nut with an accuracy of .001K (5 times higher than the aerospace standard). This ensures an exceptionally close-tolerance fit between the bolt/stud and nut.

This kit is designed to create a stronger hold on ther intermediate-block section of your Volvo S60R and V70R. Under high horspower applications, the crank can separate from the block. This ARP stud kit is designed to eliminate any separation when installed correctly.
