1UZ Swap Power Steering Pulley

Simplify your 1UZ swap and maintain smooth steering with this bolt-on Power Steering Pulley, designed explicitly for Toyota 1UZ-FE engine conversions. Whether you're building a trail rig, shop truck, or custom street cruiser, this pulley eliminates guesswork and ensures your power steering system performs as it should.

This pulley is engineered to align properly with your accessory drive system when installing a Toyota 1UZ-FE V8 engine in classic Toyota trucks and SUVs. It provides the correct belt offset and diameter to match the factory power steering pump, which is critical for clean belt routing and consistent steering assist.

This pulley is that piece. The 5.5 inch diameter is a deliberate middle ground between the smaller 4.5 inch pulleys that can overspeed a high-flow pump and the larger 6 inch and 6.5 inch pulleys that can leave steering feeling heavy at idle, giving most V8 swap accessory drives a pump speed that keeps fluid from aerating while still delivering full assist at low RPM. Every pulley is CNC machined from solid billet, black anodized, and laser engraved, so it holds tolerance and finish far better than the stamped steel pulleys found on many universal serpentine conversion kits.

Key Features & Benefits

• Correct Pump Speed: The 5.5-inch diameter keeps most TC-style pumps in a safe operating range on a 1UZ accessory drive, reducing the whine and fluid foaming that come from an oversped pump
• Precision Construction: CNC machined from 6061-T6 billet aluminum rather than stamped, so the groove profile stays true and the belt tracks cleanly instead of walking or chattering
• Durable Finish: Black anodized and laser engraved for corrosion resistance and a finished look under the hood, important on a swap where the accessory drive is often visible
• Simple Install: Press-fits onto a 0.665 to 0.667 inch pump shaft and includes a machined groove for a standard pulley puller, so no special factory tool is required

Installation & Maintenance

Installation Difficulty: Intermediate
Tools Required: Standard pulley puller and installer, torque wrench, basic hand tools
Professional Installation: Not required for an experienced DIY swap builder, but confirm belt length and pulley alignment across the crank, alternator, and pump before final installation

Maintenance Tips:

• Check belt tension and rib wear a few hundred miles after installation, since a new accessory drive layout often needs a second look once everything settles in
• Verify pulley alignment with the crank and alternator pulleys using a straightedge before the belt goes on, to prevent premature belt wear from pulley misalignment
• Listen for pump whine or growling in the first few heat cycles, which usually points to a belt length or tension issue rather than the pulley itself
• Inspect the anodized finish and laser engraving periodically for wear that could indicate belt tracking problems

Frequently Asked Questions

Q: What is a TC style power steering pump and why do 1UZ-FE swaps use one?
A: A TC-style pump is a compact, high-flow power steering pump commonly used in engine swaps because it is smaller than many factory pumps and pairs easily with a serpentine accessory drive. Toyota and Lexus V8 swap builders favor it because the factory 1UZ-FE pump and bracket rarely clear the swapped chassis without major modification, while a TC-style pump bolts into the tight space created by the swap.

Q: Why does the pulley diameter matter on a power steering pump swap?
A: Pulley diameter sets how fast the power steering pump spins relative to engine RPM, since a smaller pulley spins the pump faster for the same crank speed and a larger pulley spins it slower. Too small a diameter can overspeed the pump and aerate the fluid, while too large a diameter can leave the pump moving too slowly to build full assist at idle, so matching the pulley to your specific pump and accessory drive matters.

Q: Will this 5.5 inch pulley work with my stock 1UZ-FE power steering pump?
A: No. This pulley is sized for TC style, CB, CBX, CBR, or Type II pumps with a 0.665 to 0.667 inch shaft, which is the pump type most 1UZ-FE swap builders switch to, not the factory 1UZ-FE pump shaft. Confirm which pump you are running before ordering.

Q: Should I run a 5.5 inch pulley or a 6 inch pulley on my swap?
A: The right diameter depends on your pump flow rating and how your builder or bracket kit has the accessory drive geared. A 5.5-inch pulley is a common middle ground that keeps a high-flow TC-style pump from overspeeding while still delivering enough assist at idle, but if you are already running a 6-inch pulley without pump noise or steering effort complaints, there is no need to change it.

Q: Does this pulley include a removal or installation tool?
A: No, the pulley itself does not include a puller or installer tool. It is machined with a standard tool groove, so a common pulley puller and installer set, the kind already used for most serpentine pump swaps, will work with it.
