ARP Stainless Header Stud Kit – Gen V LT Engines #434-1401
In typically Griffin Motorsports fashion, we are always on the lookout for products that offer that perfect blend of form and function. Ditching our ugly OEM header bolts for the new ARP 12-point stainless studs was a no brainer one we realized how much easier it is to remove and install headers with them on. These high performance stainless steel studs not only look amazing when installed, but they act as a second set of hands keeping your new manifold gasket held in place while to gently finesse your long tube header of choice into position. When you install long-tube headers on a Gen V LT engine, the factory bolts can quickly turn into a weak link. Repeated installation and removal, heat cycles, vibration, can cause aluminum-head thread wear which cause the OEM bolts to loosen, contributing to possible exhaust leaks, warped flanges, inaccurate O₂ data, burnt plug wires, and power loss.
The ARP 434-1401 Stainless Header Stud Kit solves that problem for good. Designed specifically for 2014+ GM Gen V LT engines, these studs deliver higher clamping force, better heat stability, and far greater durability than stock hardware. This is the fastener kit your headers should have come with.
Product Highlights;
*Application: GM Gen V LT (M8 x 1.25 header fasteners)
*Material: ARP premium stainless steel
*Tensile Strength: ~170,000 psi (stronger than Grade 8)
*Fastener Type: Polished stainless studs w/ 12-point nuts
*Dimensions: 1.75" overall length, 1.50" thread length
Why ARP Studs Matter on LT Engines?
Headers see extreme temperature swings—ambient to 1,500°F+. Cheaper bolts lose preload or stretch. ARP’s stainless studs maintain clamp load through repeated heat cycles, keeping your header gaskets sealed and your O₂ readings accurate.
With studs, the fastener stays stationary in the head. You torque the nut—not the threads inside your aluminum cylinder head. This prevents galling, reduces thread wear, and makes future header removal far easier.
No more seized bolts. No more broken hardware. No more leaks that throw off tuning. ARP studs give you consistent sealing, clean O₂ data, and trouble-free service—even on high-boost or high-heat builds.
Perfect for daily drivers, track cars, or trucks exposed to moisture and road salt.
