The PPE 158032500 Forged XR® Tie Rods are the extreme-duty steering upgrade for 2001-2010 Chevrolet Silverado and GMC Sierra 2500 HD / 3500 HD trucks (Duramax LB7, LLY, LBZ, LMM and 6.0L/8.1L gas variants). They deliver a 35% larger 32mm ball stud, a 1.6" forged outer tie rod body (50% larger than stock), a 3/4" inner threaded shaft, and an integrated grease fitting for lasting service in lifted, oversized-tire, off-road, sled-pulling, and heavy-tow applications.
Why Upgrade? Factory GM tie rods on the 2001-2010 HD platform were the weakest link in the steering system, prone to bending, ball joint failure, and premature wear on trucks running 33"+ tires, leveling kits, or lifts. The PPE Forged XR upgrade delivers:
35% larger 32mm-diameter outer tie rod ball stud
1.6" forged outer tie rod body – 50% larger than OE
3/4" inner tie rod threaded shaft for bend resistance
Siliconized rubber boots for extreme temperature range
Integrated grease zerk on outer tie rod cap
Pre-greased from factory – no bench prep required
Preserves factory articulation angle and alignment geometry
Outer can be trimmed up to 1" for custom steering setups
PPE Lifetime Limited Warranty
Perfect for: Lifted trucks, 33"–40"+ tire builds, off-road use, sled pulling, heavy towing, and any 2001-2010 HD Duramax showing steering play or worn OE tie rod ball seats.
The PPE 158032500 Forged XR® Tie Rods are Pacific Performance Engineering's flagship steering-system upgrade for the 2001-2010 GM 2500 HD / 3500 HD platform. Engineered from extreme-duty forged steel and dimensioned well beyond OE specification, they replace the factory tie rod assemblies that are widely known as the weakest link in the GMT800/GMT900 HD steering system. Whether you are chasing steering slop from a worn factory unit, building a lifted daily-driver, or preparing a truck for competition sled pulling, the XR is designed to eliminate bending, ball joint wear, and repeat replacement cycles.
Why 2001-2010 HD Owners Choose the PPE 158032500 Tie Rods: The OE tie rods on LB7, LLY, LBZ, and LMM Duramax trucks (as well as the 6.0L and 8.1L gas variants) rely on plastic ball joint seats that wear rapidly under the load of larger tires and lifted geometry. The result is steering wander, uneven tire wear, and eventual ball joint failure. The Forged XR replaces both inner and outer tie rod ends with dramatically oversized forged components while preserving the factory articulation angle so alignment specs remain achievable.
2x Forged XR Outer Tie Rod Assemblies – 32mm ball stud, 1.6" forged body, integrated grease zerk
2x Forged XR Inner Tie Rods – 3/4" threaded shaft, forged construction
Siliconized Rubber Ball Joint Boots – Pre-installed, extreme-temperature rated
Jam Nuts & Hardware – All required steering hardware for install
Pre-Greased Assemblies – Ready to install out of the box
The 2001-2010 GM HD steering system was designed for stock tire sizes and factory ride height. Any deviation — leveling kit, lift, 33"+ tires, off-road use, heavy towing — accelerates failure of the OE tie rods.
Plastic Ball Joint Seat Wear – Factory tie rods use plastic seats that compress and degrade, producing steering play and death wobble on lifted trucks.
Bent Tie Rods – The thin OE outer body bends easily from curb strikes, off-road impacts, or hard cornering on oversized tires.
Ball Stud Pull-Out – Undersized OE ball studs can pull through the knuckle taper under sustained heavy load.
Uneven Tire Wear – Worn tie rods cause toe drift, wearing the inside or outside edges of expensive tires prematurely.
Steering Wander & Death Wobble – The most common symptom, especially on lifted trucks with 35"+ tires.
Excessive play in the steering wheel at highway speed
Clunking or knocking from the front end during turns or over bumps
Visible slop when moving the tire side-to-side by hand
Uneven or feathered tire wear on the front axle
Vehicle wanders in a straight line and requires constant correction
Failed alignment (unable to hold toe spec)
Death wobble on lifted trucks over 35 mph
Bend Resistant – The 1.6" forged outer body virtually eliminates bending from curb strikes or off-road impact
Zero Plastic Seats – Forged construction throughout replaces the failure-prone OE plastic ball joint seats
Serviceable – Integrated grease fittings allow ongoing service to extend life indefinitely
Lift-Ready – Preserves factory articulation angle so lifted trucks can still achieve alignment spec
Sled Pull & Off-Road Rated – The same design used in competition trucks running 40"+ tires
Direct Fit – Bolts to factory pitman arm, idler arm, and steering knuckles without modification

Pro Tip: While this is a well-within-DIY-scope install for an experienced wrench, the job requires a proper tie rod separator (a "pickle fork" will damage the boots) and a follow-up 4-wheel alignment. Budget for the alignment in your install cost — running new tie rods on the old alignment settings will chew tires within hundreds of miles. Most shops can handle installation and alignment locally, or we'll help you find a qualified installer.
Stock Trucks: Direct replacement – ideal for high-mileage trucks with worn OE tie rods
Leveled / Mild Lift (0-3"): Excellent match – restores tight steering feel with headroom for larger tires
Lifted Trucks (4-8"): Highly recommended – OE tie rods will not survive lifted geometry with 35"+ tires
Off-Road / Sled Pull / Competition: Preferred baseline upgrade
Towing: Superior wear life vs OE under sustained heavy load
A. Yes. The Forged XR was specifically designed for lifted trucks running oversized tires. The 32mm ball stud and 1.6" forged body handle the increased leverage from larger tires without bending, and the pre-set articulation angle keeps you within factory alignment range on lifts up to approximately 6". For builds beyond that, verify your drop bracket / lift kit provides adequate steering geometry correction.
A. The 158032500 is specifically listed for 2500 HD and 3500 HD applications. Some customers have reported successful fitment on 2001-2007 Chevrolet Silverado 1500 HD 8 Lug trucks (which share the GMT800 HD steering geometry), but PPE does not officially list 1500 HD in their fitment guide. Contact us with your VIN before ordering if you have a 1500 HD.
A. Yes. Any time tie rods are replaced, a four-wheel alignment is required to set proper toe and prevent rapid tire wear. Plan on an alignment appointment within the first 50-100 miles of driving. If you are experienced with a tape measure and can match the length of your old tie rods before installing the new ones, you can drive to the alignment shop safely — but do not skip the alignment.
A. Each PPE Forged XR tie rod ships pre-greased and ready to install. No bench prep is required. The integrated zerk fitting on the outer tie rod cap allows ongoing service — plan to grease at the same interval as your other chassis grease points.
A. Yes. The outer tie rod body can be trimmed off by up to 1 inch to achieve a shorter overall assembly length. This is useful for builds with modified steering geometry, custom knuckles, or extreme lifts requiring shorter linkage. Do not exceed the 1" trim limit — going shorter compromises thread engagement and boot sealing.
A. Yes. The 158032500 is designed to fit the full 2001-2010 GMT800 and GMT900 HD platform, including the transitional 2007 Classic body style. The outer tie rod ball stud taper matches the OE knuckle across all years covered.
A. PPE covers the Forged XR series with a Lifetime Limited Warranty against defects in materials and workmanship. NorCal Diesel Performance facilitates warranty claims directly with PPE — you don't have to chase paperwork alone. Coverage excludes damage from collision, off-road impact beyond design intent, improper installation, or use of a pickle fork during removal (which damages the boots).
A. Here is our comparison:
Moog OE-Replacement: A step above stock but still uses similar geometry and materials. Fine for stock trucks, insufficient for lifted or oversized-tire builds.
Kryptonite Death Grip: Comparable philosophy to the PPE XR — extreme-duty forged construction. Excellent product; the choice between the two often comes down to inventory and price.
Cognito: Cognito focuses more on the pitman/idler side and integrates well with the XR — many customers run PPE tie rods with a Cognito support kit for a complete steering upgrade.
PPE Forged XR: Best-in-class ball stud diameter (32mm) and forged body dimensions in this price tier, with the lifetime warranty backing.
A. Yes. Tie rods are a suspension/steering component with zero effect on the emissions system, engine calibration, or aftertreatment. The PPE Forged XR is fully legal for street use in all 50 states including California, and installation has no emissions or CARB implications.
A. You'll need these basic tools. This is an estimate, actual tools may vary.
Tie rod separator (do not use a pickle fork — it destroys the boots)
21mm and 20mm sockets (deep sockets recommended)
Torque wrench
Tape measure (to match old tie rod length before install)
Floor jack and jack stands
Standard hand tools
