Apex ProLock Tie Rod & Drag Link Assembly — SKU: KIT125 — Polished Aluminum | Dana 30/44 Narrow Axle | Flip Kit (Over-Knuckle) | Jeep Wrangler JL 2018–2026 / Gladiator JT 2019–2026 4WD

Overview

This is a complete replacement tie rod and drag link kit for the Jeep Wrangler JL and Gladiator JT — a highly polished 2" 7075-T6 aluminum tie rod and drag link, each using forged steel tie rod and drag link ends with an E-coat finish, Apex's ProLock keyway washer system, and zerk-fitting serviceability. This exact configuration is built for the Dana 30 / narrow Dana 44 front axle and is set up as a Flip Kit (over-knuckle mount), including the required taper sleeve.

Before ordering: This kit fits the Dana 30 or narrow Dana 44 front axle only — typically found on non-Rubicon trims (Sport, Sahara). Wide Dana 44 axles (typically Rubicon, Mohave, Max Tow Package) require a different, wide-axle version of this kit — not this SKU. To confirm your axle width, measure ball-stud center to ball-stud center on your factory tie rod: narrow Dana 44 measures 57½"–58½"; wide Dana 44 measures 60½"–61½". This configuration is the Flip Kit (over-knuckle mount) and requires drilling the knuckle drag link mount through with a straight 7/8" drill bit to install the included taper sleeve — this is typically suggested for lifts over 4.5". If your Jeep has been upgraded to a Dana 60 axle, contact Apex directly for available modifications; this kit as configured does not cover that application.

Required separately: A steering stabilizer bracket is not included and must be selected separately based on the steering stabilizer you run. Apex jam nut wrenches KIT521 (2x WR112 41mm/46mm) are required for installation and are not included with this listing. A steering stabilizer, thread locker (blue Loctite 243 or Permatex 24206), anti-seize for adjusting-sleeve threads only, and a professional alignment are also required and not included.

Verified Fitment

Wide Dana 44 axle trucks (typically Rubicon, Mohave, Max Tow Package) require the wide-axle version of this kit — not this SKU. Dana 60 upgrades require contacting Apex directly.

Component Specifications

What Is and Is NOT Included

Included:

• Complete tie rod assembly — 2" 7075-T6 polished aluminum adjusting sleeve, forged steel E-coated ends (TR181K, TR182K)
• Complete drag link assembly — 2" 7075-T6 polished aluminum adjusting sleeve, forged steel E-coated ends (DL112KF, DL111K)
• Taper sleeve (Flip Kit configuration)
• ProLock keyway washers and Belleville washer alternates
• Jam nuts with integrated set screws
• Grade 8 / Class 10.9 hardware, castle nuts
• Zerk fittings (pre-threaded, pre-greased)

Not included:

• Steering stabilizer bracket (must be selected separately based on the steering stabilizer used)
• Steering stabilizer
• Jam nut wrenches (KIT521, 2x WR112 41mm/46mm — required for installation, sold separately)
• Replacement set screws (XP172, tie rod and drag link, sold separately)
• Thread locker (blue Loctite 243 or blue Permatex 24206 recommended)
• Anti-seize compound (for adjusting sleeve threads only)

Critical Compatibility

• Axle width: This configuration fits the Dana 30 or narrow Dana 44 front axle only. Confirm by measuring ball-stud center to ball-stud center on your factory tie rod: 57½"–58½" indicates narrow Dana 44 (correct for this kit); 60½"–61½" indicates wide Dana 44, which requires a different kit.
• Dana 60 upgrades: Not covered by this configuration. Contact Apex directly for available modifications.
• Flip Kit (over-knuckle mount): Requires drilling the knuckle drag link mount through with a straight 7/8" drill bit to install the included taper sleeve. Typically suggested for lifts over 4.5".
• Washer selection: Use either the ProLock keyway washer or the Belleville washer to secure a given jam nut — never both on the same joint.
• Anti-flop bearing (tie rod): Allows approximately 4° of forward/back rotation once properly installed. Tighten the passenger side jam nut first, then center the flop while tightening the driver's side jam nut, so approximately 4° of rotation remains once both are torqued.
• Minimum engagement mark — drag link: If visible on the drag link end threads, thread engagement is insufficient. A flip kit or re-equalized adjusting sleeve may be required.
• Grease volume: Zerk fittings are metal-on-metal and pre-greased. Add only ½ to 1 pump of high-pressure lithium grease per fitting — over-greasing can cause the boots to balloon and fail.
• Polished finish care: Polished raw aluminum is uncoated and will oxidize/dull with exposure unless periodically maintained; this is a cosmetic characteristic of the finish, not a defect.
• Steering stabilizer bracket: Not included with this kit — select the correct bracket separately based on your steering stabilizer.

Installation Notes

Steering components are safety-critical. Professional installation is strongly recommended, and a professional alignment must be completed before operating the vehicle. The installer must follow the current Apex Chassis Flip Kit installation instructions supplied with the product throughout installation and alignment, including drilling the knuckle for the taper sleeve.

Required for this configuration: Apex jam nut wrenches KIT521 (2x WR112 41mm/46mm), sold separately; medium-strength blue thread locker (Loctite 243 or Permatex 24206); anti-seize compound for the internal adjusting-sleeve threads only; and a straight 7/8" drill bit for the knuckle taper-sleeve hole.

Tie rod ball-stud tension nuts torque to 63–67 ft/lbs; drag link castle nuts torque to 75–82 ft/lbs; jam nuts on both assemblies torque to 200 ft/lbs; jam-nut set screws torque to 8–10 ft/lbs, applied only after alignment. The tie rod's ProLock keyway washers are tapped onto the adjusting sleeve after alignment. Before operating the vehicle, verify correct application, steering geometry, adequate thread engagement, and full lock-to-lock clearance.

Inspect jam-nut position after the initial 500 miles and then every 5,000 miles or at each oil change, consistent with Apex's maintenance guidance. Refer to the current Apex Chassis installation instructions supplied with this kit for complete procedures, torque specifications, and all safety requirements.

The Obsidian Take

This KIT125 configuration is Apex's polished aluminum tie rod and drag link kit for the Jeep Wrangler JL and Gladiator JT running the Dana 30 or narrow Dana 44 front axle — set up as a Flip Kit for lifted applications, with the taper sleeve included. Confirm these application conditions before ordering: this kit is axle-width specific, so measure your factory tie rod before ordering if you're unsure whether your Dana 44 is narrow or wide, and the Flip configuration requires drilling the knuckle for the taper sleeve. Jam nut wrenches (KIT521) and a steering stabilizer bracket are not included and must be ordered separately.

This Product Is For You If

• You own a 2018–2026 Jeep Wrangler JL or 2019–2026 Gladiator JT with a Dana 30 or narrow Dana 44 front axle (typically Sport or Sahara trim).
• You are running a lift over 4.5" and want an over-knuckle (Flip) mount with the taper sleeve included.
• You prefer a polished aluminum appearance.
• You are prepared to drill the knuckle with a straight 7/8" bit as part of installation.
• You are prepared for a professional-level installation with specific torque values and a required professional alignment.
• You are prepared to select and purchase jam nut wrenches (KIT521) and a steering stabilizer bracket separately.

This Product Is Not For You If

• Your Jeep has a wide Dana 44 front axle (typically Rubicon, Mohave, or Max Tow Package trim) — you need the wide-axle version of this kit, not this SKU.
• Your Jeep has been upgraded to a Dana 60 axle and you have not contacted Apex to confirm available modifications.
• You need a standard under-knuckle mount rather than the Flip (over-knuckle) configuration.
• You are not prepared to drill the knuckle for the taper sleeve.
• You prefer a black finish — see KIT120 (black anodized aluminum).
• You do not already have, or are not ordering, jam nut wrenches (KIT521) and a steering stabilizer bracket matched to your stabilizer.
• You plan to use both ProLock and Belleville washers on the same joint — use one or the other only.

Common Questions

How do I know if I have a narrow or wide Dana 44?
Measure your factory tie rod ball-stud center to ball-stud center. 57½"–58½" is narrow Dana 44 (this kit applies). 60½"–61½" is wide Dana 44 (a different kit is required).

Does this fit the Rubicon?
Rubicon trucks typically run the wide Dana 44 axle, which requires the wide-axle version of this kit, not this narrow-axle SKU. Confirm your axle width by measurement if unsure.

What's the difference between the standard and Flip Kit mount?
The standard mount is under-knuckle. The Flip Kit is an over-knuckle mount, includes the taper sleeve, and requires drilling the knuckle through with a straight 7/8" bit. It's typically used for lifts over 4.5".

Is a steering stabilizer bracket included?
No. It must be selected separately based on the steering stabilizer you use.

Are jam nut wrenches included?
No. Apex jam nut wrenches KIT521 (2x WR112 41mm/46mm) are required and sold separately.

Can I use Belleville washers instead of the ProLock keyway washers?
Yes, on the applicable joints — but never use both a ProLock and a Belleville washer on the same joint.

Does the polished finish need maintenance?
The polished aluminum is a raw, uncoated finish and may oxidize or dull with exposure over time. If you prefer a coated finish, see KIT120 (black anodized).

Is a professional alignment required?
A professional alignment must be completed before operating the vehicle. Professional installation is strongly recommended. Thread locker and set-screw torque are applied only after alignment.

What is the replacement set screw part number?
XP172, for both the tie rod and drag link.

What is the warranty?
Apex covers manufacturer defects, premature wear, and breakage for the life of the vehicle, as long as the original purchaser owns the vehicle, with product registration required within 90 days of purchase. See full warranty summary below.
