The best semi truck steering gear box depends on the truck’s make, model, year, and existing gear-box part number. The BuyAutoParts TAS65004 replacement is the broadest listed option for several truck brands, while the International TAS65079 remanufactured unit and FleetRun Freightliner gear target specific applications. A Ford motorhome and Peterbilt listing offers another fit-specific choice. The maXpeedingrods box is for older GMC and Chevrolet pickups, not a semi truck.

BuyAutoParts 82-00459AN TAS65004 Gear Box
Best for: Buyers whose truck uses the TAS65004 replacement and is among the listed Mack, Kenworth, Peterbilt, International, Freightliner, Ford, Chevrolet, or GMC applications.
This new gear box is described as a guaranteed exact fit and is intended to work with the original steering shaft and linkage. The product details also state that it has no core deposit or return requirement and includes a three-year, unlimited-mileage warranty. It is the broadest multi-make option in this group, but a long make list does not confirm fit for every truck in those lines.
Why it was selected: The TAS65004 reference and shaft-and-linkage detail give buyers useful identifiers to compare with the part being replaced. Verify the truck’s exact application and existing part number before ordering. Avoid choosing it based on brand alone.
BuyAutoParts 82-01270R International TAS65079
Best for: Buyers replacing a steering gear in a compatible International semi truck that uses TAS65079.
This is a remanufactured unit, described as fully remanufactured and tested to OEM/OES standards. Its listing says it fits like the original and retains the stock steering ratio. The product information also states a three-year, unlimited-mileage warranty. These details make it a focused alternative when the truck’s original gear number matches the listed replacement.
Why it was selected: It is specifically identified for International trucks and provides the steering-ratio detail that matters when matching a replacement. It is remanufactured rather than new, so buyers who require a brand-new assembly should compare another option. Confirm exact fitment before purchase.
FleetRun FR-STRG454 Freightliner Gear Box
Best for: Freightliner Century owners whose required gear matches one of the listed replacement numbers.
FleetRun lists OEM numbers 14-19708-000, 14-17727-000, 14-17726-000, and 14-15701-000, as well as TRW THP60010. The listing offers a six-month or 50,000-mile warranty from installation, whichever comes first. It also says buyers can contact the seller for a VIN-based parts search.
Why it was selected: Its specific Freightliner Century application and multiple cross-reference numbers help narrow the search. The listing explicitly advises buyers to verify compatibility and disclaims responsibility for fitment issues. Check the truck’s VIN and existing part number before ordering; do not assume every Century uses this gear.
BuyAutoParts 82-00695AN Peterbilt Gear Box
Best for: Buyers matching a listed Peterbilt or Ford motorhome application to this specific new gear box.
The listing describes the unit as 100% brand new and engineered to meet or exceed OEM specifications. It also states that the part is tested for quality and backed by a three-year, unlimited-mileage warranty. Although the title mentions Peterbilt and Ford motorhomes, the supplied details do not identify specific truck years, models, or replacement numbers.
Why it was selected: It provides a new-unit option for buyers whose application is covered by the listing. The main caution is that the available product information offers limited fitment identifiers. Confirm the part number and vehicle details with the seller before purchase rather than relying only on the broad title.
maXpeedingrods CP50014 Pickup Gear Box
Best for: Owners of the specified 1969–1987 GMC C1500 or Chevrolet C10 with power steering—not semi-truck buyers.
The listed part numbers are CP50014 and SGB10TRK. The product description says the unit is made with high-quality materials and is designed to provide steering response and a smoother steering experience. Its stated vehicle applications are older light-duty pickups, which makes it a poor match for a heavy-duty commercial truck unless a qualified parts source confirms otherwise.
Why it was selected: It is the only supplied listing with a clearly stated pickup application, so it is useful for separating light-truck fitment from semi-truck parts. Avoid this option for a semi truck based on the information provided. Check the vehicle year, model, and part number before ordering.
Buying Guide: How To Choose A Semi Truck Steering Gear Box
Which fitment details should you check?
Start with the truck’s make, model, and year, then compare the existing steering gear’s identification or replacement number with the product listing. A brand match alone is not enough: one manufacturer may use different steering gears across models or configurations. If a listing provides OEM or cross-reference numbers, use them as a shortlisting tool and confirm the exact application before buying.
Should you choose a new or remanufactured unit?
A new unit, such as the two BuyAutoParts options described as new, may suit buyers specifically seeking a new assembly. The International TAS65079 listing is remanufactured and says it is tested and retains the stock steering ratio. Compare the condition stated in the listing, the fitment evidence, and warranty terms. The supplied information does not establish that one type is universally better.
How important are steering ratio and linkage details?
Steering ratio affects how the replacement corresponds to the original steering gear, while shaft and linkage details help determine whether the assembly matches the existing setup. The TAS65079 listing explicitly mentions the stock steering ratio, and the TAS65004 listing says it works with the original shaft and linkage. Confirm these details against the gear being replaced when available.
What should you verify before ordering?
- Compare the truck’s details and old gear number with the product’s listed applications.
- Ask the seller to check fitment by VIN when that service is offered.
- Read the stated warranty period and conditions; warranty terms differ among these listings.
- Do not treat a pickup-truck gear box as a semi-truck part without verified fitment.
Frequently Asked Questions
Can I choose a steering gear box by truck make alone?
No. Confirm the model, year, and steering gear part number because applications can vary within one make.
Is the International TAS65079 option new?
No. The listing identifies the 82-01270R unit as remanufactured and tested.
Which listed gear box is for a Freightliner Century?
The FleetRun FR-STRG454 is listed for Freightliner Century and references several OEM numbers, including 14-19708-000 and TRW THP60010. Verify your exact fitment.
Is the maXpeedingrods box suitable for a semi truck?
The supplied application information names GMC C1500 and Chevrolet C10 pickups from 1969–1987. It does not identify a semi-truck application.
Do all these products have the same warranty?
No. The supplied listings state different warranty terms, and the maXpeedingrods details provided do not specify a warranty. Check the product information for current terms.
