Why Choose 100% Genuine Toyota OEM Parts?
✓ Complete Kit — Do It Once, Do It RightBelt, tensioner pulleys, and idler pulleys share the same service life. Replacing them together prevents the #1 mistake: installing a new belt on worn pulleys that destroy it within months. This kit gives you everything in one purchase. ✓ Precision Bearings & Belt CompoundOEM pulleys feature sealed bearings designed for the 1GR-FE's specific RPM and load demands. The OEM belt uses Toyota's exact rubber compound and ribbing specifications for quiet, slip-free operation. ✓ Eliminates Squealing & Belt NoiseWorn pulleys and stretched belts are the #1 cause of engine bay noise. A fresh OEM kit restores factory-quiet operation and eliminates the annoying squealing that plagues aging trucks. |
✓ Protects Critical Engine SystemsThe serpentine belt drives your alternator, A/C compressor, power steering pump, and water pump simultaneously. A snapped belt or seized pulley disables ALL of these systems — often on the trail or highway. ✓ Save Money vs Buying SeparatelyPurchasing the complete kit is more cost-effective than buying each component separately. Plus, you avoid multiple shipping charges and ensure all parts arrive together for a single repair session. ✓ Factory Warranty & SupportEvery piece in this kit is backed by Toyota's 12-month warranty. Our technical team verifies compatibility and helps you identify any additional components you may need. |
📋 Important Information
✓ 100% Genuine Toyota OEM — All 4 Pieces
Every component in this kit is genuine Toyota OEM — NOT aftermarket reproductions. Identical to parts sold at Toyota dealerships. Factory sealed packaging for each piece.
⚙️ Tensioner Assembly Sold Separately
This kit includes the belt and all 3 idler pulleys. The belt tensioner assembly (16620-31013) is sold separately. If your tensioner is original, Toyota recommends replacing it at the same time. Contact us to add the tensioner to your order.
🔍 1GR-FE 4.0L V6 Only
This complete kit is exclusively for the 4.0L V6 1GR-FE engine. If your 4Runner, Tacoma, or Tundra has a different engine (2.7L, 4.7L, 5.7L), it requires different components. Contact us with your VIN for free verification before purchasing.
