Upgrade the steering strength and precision of your Duramax-powered Silverado or Sierra HD with the Apex Chassis Front Inner Tie Rod End. Built for the demands of diesel towing, hauling, and off-road use, it features a forged SAE 1045 solid steel housing and CNC-machined construction for unmatched durability and fit. The SAE 4140 hot-forged Chromoly ball studs are induction heat-treated for extreme load resistance, while rolled and step threads ensure smooth installation and a secure hold.

A military-grade acetal bearing, used in U.S. military Humvees, provides superior stability, low friction, and long life compared to metal-on-metal designs. Heavy-duty CR rubber boots guard against heat, oil, and debris, and Grade 8 hardware with a castle nut guarantees a solid connection. Pre-greased and greaseable with Gull Winged grease grooves and a zerk fitting, this tie rod end is ready for the toughest diesel applications on 2011–2024 Silverado and Sierra 2500HD and 3500HD trucks.

HOUSING

• SAE 1045 Solid Steel Forged Housing: This is unequivocally the best carbon alloy steel for this application.
• CNC Machined Housing: Make our parts and bearings dimensionally perfect, eliminating any die wear issues.

BALL STUDS

• SAE 4140 hot forged Chromoly Ball Studs: For the strongest possible metallurgy.
• Induction Heat Treated Ball Studs: Provides a very precise heat treatment to the exact depth and location we want it.
• Rolled Threads: Are made by pressing the shape of the threads into the ball stud instead of cutting. This strengthens the threads instead of weakening them and allows for easy movement of hardware. This ain't no Ikea furniture!
• Step Threads: Allows for very easy movement of hardware on install and superior holding when torqued (installer choice).

BEARING DESIGN

• Military Grade Acetal Bearing: The same bearing material spec'd by the US military for Hummer ball joints. This material is dimensionally stable (doesn't expand or contract with hot or cold, water or oil absorption), can be polished smooth as steel, is anti-friction, doesn't wear itself out under load like metal on metal, and can take an absolute pounding.

BOOTS

• CR Rubber Boots: The most durable material for undercar applications. Resistant to deterioration from road-level ozone, oil, gas, engine fluids, and extreme heat or cold.
• Compression Boot

HARDWARE

• Grade 8 - Class 10.9 Hardware: Superior tensile strength.
• Castle Nut: Industry standard where high vibration loads occur.

LUBRICATION

• Greaseable: Because it should be.
• Pre-Greased: Just in case you forget, we have you covered.
• Gull Winged Grease Grooves: Allows for improved lubrication disbursement around the ball stud.
• Zerk Fittings: No, needle-style grease port in boot.
