ARP HEAD STUDS TO SUIT TOYOTA 1HD-FT & 1HD-FTE ENGINES

Description

These are a great upgrade for those who plan to increase the performance of their 1HD-FTE around the 400HP and 1000nm mark. ARP head studs significantly increase the clamping force on the cylinder head down to the engine block.

– Direct Replacement Fit: 11mm ARP Head Stud Kit includes 26 studs and hardware, with no modification needed for head bolt holes in the block or head.

– Increased Clamping Force: Provides 40% greater clamping force than stock torque-to-yield bolts, resulting in improved performance and reliability.

– Even Torque Distribution: Eliminates twisting force during tightening, offering more accurate and evenly distributed torque load, reducing the risk of head gasket failure.

– Enhanced Clamping Force: Stock TTY head bolts provide around 11,000lbs of force, while ARP studs average 15,785lbs of force for improved clamping.

– Installation Instructions Included: Comes with detailed instructions; ARP Ultra Torque lubricant should be used under the nut and washer when torquing.
