## Overview

The ARP 2084305 High Performance 12-Point Cylinder Head Stud Kit is a USA-made, vehicle-specific upgrade designed for Honda Civic D16Y7 engines. Manufactured from premium 8740 alloy steel and heat-treated to 200,000 psi, these studs offer exceptional strength and fatigue resistance. Precision centerless grinding and post-heat-treat thread rolling ensure perfect alignment and 10x better durability, while a unique undercut design optimizes clamping force to prevent head gasket failure—making it the go-to choice for sport compact racers and performance enthusiasts.

## Description

(D16Y7) Built for the Honda Civic... Obtaining the optimum cylinder head-to-block sealing is especially critical in small displacement engines employing high compression pistons or power adders like turbochargers, nitrous oxide and superchargers. That's why ARP head studs are popular among leading Sport Compact/Import racers.You should know that ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Then, each stud is precisely heat-treated to 200,000 psi. Following heattreat, each stud is centerless ground to make it as close to perfectly concentric as possible. This procedure involves about ten very slight cuts and results in an exceptionally straight part. It's important to note that lesser quality studs are not even centerless ground the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP studs are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned something that won't happen with inferior quality head studs.ARP studs are thread rolled after heat-treat, which gives them about 1000% (that's ten times) better fatigue strength than those studs that are threaded prior to heat-treat.You will also note that ARP offers specially undercut studs for several engines. This procedure (done only to the shorter studs) more equalizes the "stretch" of both studs, which makes for a more consistent clamping force one that compensates for head gasket compression when the head is installed. This helps prevent blown head gaskets, and assures optimum sealing!
