ARP 2000 Head Stud Kit – Gen V LT (LT1/LT4) #234-4342
When you start leaning on a Gen. V LT engine by adding more boost, more RPM, more timing, the factory torque-to-yield head bolts become a major weak link. Head lift, inconsistent clamping, and marginal gasket life are all symptoms of fasteners that were never designed for 15+ psi, and the types of cylinder pressures seen on builds over 700rwhp.
For those adding horsepower and torque by way of upgraded internals like a larger camshaft and ported cylinder heads, the ARP 234-4342 head stud kit is the fix. It replaces the OE head bolts on your LT1/LT4 with aerospace-grade studs designed to keep the heads clamped flat and happy under serious cylinder pressure, pull after pull, lap after lap.
At Griffin Motorsports, we run this platform the way you do, hard. So we stock these studs not as a “nice upgrade,” but as a core reliability part that belongs on any serious LT build, especially when you’re already in there for cams, pistons, or heads.
Why Upgrade to ARP Head Studs on a Gen V LT?
1. Stronger material = more clamping force
Manufactured fromARP2000 alloy, these stud bolts are heat-treated to an approximate 220,000 psi tensile strength which is far beyond typical OEM head bolt material.
That higher tensile strength lets you apply more usable clamping load without stretching the fastener, which directly improves head gasket sealing at high cylinder pressures.
2. Better thread geometry & load control
ARP studs areprecision centerless-ground and thread-rolled to Mil-S-8879 specifications after heat-treat, which significantly increases thread fatigue strength compared to cutting threads first and then heat-treating.
Supplied withhardened, parallel-ground washers that spread the load evenly across the head surface, giving more consistent torque and less distortion around each fastener.
3. Studs / bolts for boosted and high-RPM builds
Compared to factory torque-to-yield bolts, studs offer:
More accurate torque because you’re rotating a nut against a stationary stud, rather than twisting a long bolt through the fragile threads in the block.
Reduced wear on block threads, which matters when you’re assembling and disassembling the top end multiple times during a build or development process.
Improved alignment of the head and gasket during installation since the head drops over fixed studs instead of “floating” on loose bolts.
4. Designed for real-world abuse
Black oxide finish helps protect against corrosion and galling in harsh environments (track, road salt, moisture).
12-point nuts make it easier to work around rocker stands, springs, and tight firewall/strut tower areas.
If you’re pushing the boost, running alot of timing, doing repeated highway pulls, or living at the race track, this kit dramatically reduces the risk of head-gasket issues and “mystery” coolant loss that creeps in as power levels go up.
Kit Includes:
* Complete set of head studs for both cylinder heads
* 12-point nuts + Hardened washers
* ARP installation instructions (torque pattern, lube usage, and recommended torque values)
Important: This is the “no M8 corner bolt” kit. If your combination uses heads and blocks that do run corner bolts, you’d need the related ARP kit that includes those (234-4343), not this one.
Why Buy Your ARP Studs from Griffin Motorsports?
Although there are a lot of great places to buy ARP hardware online these days. None of them will offer you special bundle discounts on large orders like we can thanks to a low overhead and passion for helping you GO FAST for less.
LT-Only Obsession: Griffin Motorsports is built around the 6th-Gen Camaro and Gen V LT platform. If you’re building an LT1/LT4, this isn’t just “another product category” for us, it’s all we think about.
Fitment Guide – ARP 234-4342 (Gen V LT, No Corner Bolts)
Engine families (primary): 6.2L LT1 – Gen V
This kit is specifically marketed for Gen V LT1 and LT4 6.2L engines without the M8 corner head bolts.
Common vehicle applications;
*2014–2019 Corvette Stingray & Grand Sport (LT1)
*2015–2019 Corvette Z06 (LT4)
*2016–2023 Camaro SS (LT1)
*2017–2024 Camaro ZL1 (LT4)
*2016–2019 Cadillac CTS-V (LT4)
Fitment Note: GM used more than one head/block configuration on Gen V engines. Before ordering, confirm that your heads and block do not utilize M8 corner head fasteners. If you’re unsure, contact Griffin Motorsports with your VIN and engine details and we’ll help you verify the correct kit.
