2G DSM / Mitsubishi Evolution 8/9 ARP Head Stud Kit 207-4203
*Currently on a 4-6 week backorder*
At MAPerformance.com, we appreciate many forms of “mechanical ingenuity.” But sometimes, the inner MacGyver needs to be silenced. When it comes to high-performance engines, a less-than-perfect solution or low-quality parts can lead to disastrous results.
Simply put, we love APR head studs for their quality and strength. The head studs in this kit are designed specifically for the 2003-2006 Mitsubishi Evo 8/9, and for 1994.5-1999 DSM-7 Bolt 4G63T engines. They are engineered with one purpose; handle high heat and stress.
It starts with the material — ARP uses a premium-grade 8740 alloy heat treated for a tensile strength of 200,000 psi. Using a centerless grounding procedure with a series of specific, slight cuts, each stud is nearly perfectly concentric. Each stud is then thread rolled after a heat treat for a strength upgrade of about 10 times better fatigue strength than so many other studs on the market that are threaded before the heat treat. Each kit comes with 8740 chromoly steel 12pt nuts, parallel ground washers and ARP’s Ultra-Torque fastener assembly lubricant.
You’ve put a lot of time and money into your Evo 9 engine. Protect that investment with some of the best head studs on the market.
