3SX Stud Kits for Upper Engine - Various - 3000GT Stealth

3SX Upper Engine Stud Kits

3SX has another brand new development to offer! These are STUD kits for various components of the upper engine, particularly parts that are "frequently" removed. With the intake manifolds being cast aluminum, they are a soft metal, and the female threads for the mounting bolts can get stripped, especially over time as you have to change spark plugs, gaskets, and other maintenance items. The worst thing about doing an easy job is when something as simple as a bolt thread strips, making that easy job a royal pain!

3SX Upper Engine Stud Kits offer a permanent solution to that stripped out bolt-hole problem. Each kit includes fitted studs and stainless steel nuts for the various applications. The pictures below highlight the kits available and which studs/nuts are included.

NOTE: We recommend using Loctite when installing the studs to hold them in the piece they are threaded into. We *include* the threadlocker with the Complete Kits.

 

LOWER Intake Plenum/Manifold
( Mount Upper Plenum to Lower Pleum)

This kit includes 5 studs and 7 nuts that thread into the lower intake manifold for mounting the upper intake plenum.

 

Upper Intake Plenum Accessories
(to Mount Accessories to Intake Plenum)

This kit includes various studs and nuts that allow you to mount the various accessories to the top side of the plenum. Note that it does not include studs for EGR valve/pipes or the rear support brackets.

Harness on Throttle Body Side
Fuel Injector Harness Cover (front)
Harness/IC Pipe Bracket on Driver's Side

Throttle Body
(to Mount TB to Intake Plenum)

This kit includes 4 studs and 4 nuts that thread into the throttle body port of the upper intake plenum.

Fuel Rails
(to Mount Rails to Lower Intake Plenum)

This kit includes 4 studs and 4 nuts that thread into fuel rail support arms of the lower intake plenum.

NOTE: This kit will not work with some aftermarket fuel rails (including the 3SX rails) as the nuts are a larger diameter than the holes they recess into in the fuel rail so will not properly thread onto the stud. The kit works fine with the stock fuel rails.

Thermostat Housing / Water Distribution Housing
(to Mount to Heads, Mount Neck & Cover to Main Piece)

This kit includes 4 studs and 4 nuts that thread into heads where the water housing mounts. Also 5 studs and nuts for mounting the water fill neck and thermostat cover to the main distribution piece.

 

Loctite 243 Blue Medium Strength

The Complete 3SX Stud Kits include a 0.5ml tube of Loctite. It is also available separately.

Loctite® 243™ Primeless threadlocker is designed for the locking and sealing of threaded fasteners between 1/4" and 3/4" (6 to 20 mm), which require normal disassembly with standard hand tools. Product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. The thixotropic nature of Loctite 243 reduces the migration of liquid product after application to the substrate. Provides robust curing performance. It not only works on active metals (e.g. brass, copper) but also on passive substrates such as stainless steel and plated surfaces. Offers high temperature performance and oil tolerance. Tolerates minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids.
