What this part does
Linear motion transfer from rack to wheel
The steering rack moves left and right in a straight line inside its housing. The rack end is threaded onto the end of this rack bar, so it moves with the rack. As the rack translates, the rack end pushes or pulls the outer tie rod (and with it the steering knuckle), swinging the front wheel through its steering angle. Without the rack end's articulating joint, the outer tie rod could not accommodate the angular change between the horizontal rack motion and the arc the tie rod follows as the suspension rises and falls.
Ball-and-socket articulation inside the bellows
The rack end contains an internal ball-and-socket joint — similar in principle to the outer tie rod end but larger in section because it is under higher force at this point in the linkage. This joint allows the rod to pivot in multiple planes as the suspension travels, preventing the steering from binding through bumps. The entire rack end assembly lives inside the steering rack bellows boot, which keeps road grit, water and salt away from the joint and the rack surface itself.
Toe adjustment via thread engagement
The outer tie rod end threads onto the rack end's threaded shaft with a jam nut that locks the assembly at the correct length. Turning the outer tie rod end in or out on this thread changes the effective length of the tie rod, adjusting front toe. During a wheel alignment, the technician unlocks this jam nut and turns the outer tie rod end to set toe, then re-tightens the jam nut. The rack end itself is not adjusted during routine alignment work.

Where the rack end is used
Rack ends are used on rack-and-pinion steering, which is fitted to most current passenger cars and SUVs and to many light commercial vehicles. One rack end threads into each end of the steering rack, inside the rubber bellows, and the outer tie rod end threads onto it.
Sourcing notes for buyers
Rack ends vary in length, in the thread that goes into the rack and in the thread that takes the tie rod end. Left and right rack ends may share an OE number or differ, depending on the rack. The rack end and the tie rod end are separate categories in this catalogue, each with its own OE numbers; give both numbers when a repair needs both parts.

How OE cross-referencing works
An OE (original equipment) number is the part number a vehicle maker gives a component. Each part in this catalogue is listed under the OE numbers it replaces and under the equivalent numbers other parts makers use, so the same part can be found from any of those codes.

What is a rack end?
A rack end — also called the inner tie rod end or inner tie rod socket — is the threaded pivot assembly that screws into or onto the end of a rack-and-pinion steering rack and connects it to the outer tie rod end. It is the innermost joint in a rack-and-pinion steering linkage, directly attached to the moving rack bar, and it transmits the rack's linear motion to the adjustable tie rod assembly that steers each front wheel. Every rack-and-pinion vehicle has two rack ends, one per side.
How many rack ends do you carry?
3,016 OE numbers across 102 vehicle brands. Use the brand chips above to filter by your target vehicle.
Are these aftermarket or genuine OEM parts?
Aftermarket. SLOOP has been forging chassis components at our Taichung factory since 1984. We reference OEM part numbers under nominative fair use solely to identify vehicle compatibility — every part is form-fit-function tested against the listed OE specifications.
What is the minimum order?
USD 5,000 invoice minimum. In-stock parts: 20 pcs minimum per part. Make-to-Order parts: 1,000 pcs minimum per part (USD 5,000 auto-satisfied at MOQ). T/T payment, ships globally from Taiwan.
How fast can you ship?
In-stock parts ship in 15–30 days from PO. Make-to-Order parts are 90–120 days (forge → machining → finishing → QC → packing). Sea freight from Taiwan port (standard); air freight available on request.
How do I confirm that a rack end fits a specific vehicle?
Search its OE number. The OE number page lists the vehicles the part is cross-referenced to by make, model and year. If you only know the vehicle, use the vehicle-brand links on this page to see the OE numbers listed for that make.
Can I order these parts under my own brand?
Yes. OEM orders (your brand on a standard part) and ODM orders (a part produced to your drawing or specification) are accepted, subject to minimum quantities and, where needed, tooling discussions.
Is a rack end the same as an inner tie rod?
Yes. Rack end, inner tie rod and inner tie rod end are names for the same part: the joint that threads into the end of the steering rack.
Do left and right rack ends share an OE number?
On some racks one rack end fits both sides; on others the two sides differ. Search the OE number for each side.
