ARP Head Studs – 2001-’16 GM Duramax (ARP 2000 Material) – 230-4201

ARP cylinder head studs are the clear favorite among top professional engine builders in nearly every form of motorsports. ARP uses a premium grade 8740 alloy that is rated superior to aircraft quality. Each stud is then specially heat treated in a vertical fixture that ensures complete heat penetration. After heat treating, the studs are centerless ground for precise concentricity, and then the threads are rolled, which gives them ten times better fatigue strength than most competitors’ studs. It costs more to do it this way, and it is very hard on the tooling, but the results are well worth the extra expense. ARP stud kits are available for almost every domestic and import application. You won’t find a better product on the market from any other source. Includes 12-point nuts.

Key Features:

• No better cylinder head studs available at any cost
• 8740 alloy is rated better than aircraft quality
• All ARP studs are heat treated and feature rolled threads
• Studs make gasket and cylinder head alignment a snap
• Used by top professional engine builders in all forms of racing

Riffraff Diesel Billet 7.3L Power Stroke Oil Cooler Mounts

“Oil leaks on the 7.3 are just part of it.” Yeah, we’re not buying that—especially when the oil cooler is involved. OEM cast aluminum cooler mounts are brittle, prone to corrosion, pitting, and scratches, and can keep leaking even after fresh seals are installed. Riffraff Diesel’s Billet Oil Cooler/Filter Assemblies replace the weak cast pieces with stronger billet aluminum units with tighter tolerances, better longevity, and a much cleaner look.

Available for all Ford 7.3L Power Stroke model years (E-Series too).

AMSOIL Signature Series Fuel-Efficient 100% Synthetic Automatic Transmission Fluid

Transmissions in commercial vehicles, SUVs, trucks, and vans—particularly those used for hauling or towing—are subjected to severe service operation and increased heat. Elevated temperatures cause fluids to break down, allowing damaging metal-to-metal contact and the formation of sludge and deposits. The problem is worse in modern transmissions with more gears, clutch packs, and narrow oil passages that require clean, high-quality fluid to achieve maximum performance and life. AMSOIL Signature Series Synthetic Automatic Transmission Fluid is specially formulated to withstand the rigors of heavy towing, elevated temperatures, and challenging terrain. It remains fluid in sub-zero temperatures and provides reserve protection during heavy use and abuse.
