With the increased cubic capacity from the 101mm stroker crank, increases of up to 50% in torque and low to mid range power are achievable. Boost will come on earlier in the rev range and peak power will increase.
Note: If conrod to block interference occurs, slight clearancing may be required.

What should I be aware of regarding conrod clearance?
When installing the Spool H Beam Forged Conrods with ARP2000 bolts, be aware that conrod to block interference may occur. In such cases, slight clearancing of the block may be necessary to ensure proper fitment and avoid any potential damage during operation.
Do I need to balance the crankshaft with the rotating assembly?
Yes, it is essential to balance the Spool Billet 4340 Nitrided and Balanced Crankshaft with the full rotating assembly. This ensures optimal performance and reliability, reducing vibrations and wear on engine components.
What are the torque specifications for the ARP2000 bolts included in this kit?
The ARP2000 bolts included with the Spool H Beam Forged Conrods should be torqued to approximately 75 ft-lb using ARP Ultra-Torque lubricant. Always refer to ARP's latest instructions for the most accurate specifications.
