Mhrxusd Drive Belt Kit for Toyota 3.4L V6 (1995-2004) — 3-Piece Serpentine Set, OEM-Equivalent Sizes

If your Tacoma, 4Runner, Tundra or T‑100 with the 3.4L V6 is showing signs of belt wear, slipping, or accessory failure, this Mhrxusd three-piece drive belt kit replaces the primary front-end belts in one convenient package. The set includes three different-length belts that match common OEM sizes for accessory drive systems, so you can refresh the alternator, power steering, A/C compressor and other pulleys at the same time and reduce the chance of uneven wear.

Which Toyota models and years will these belts fit?

This kit is formulated for Toyota vehicles with the 3.4L V6 engine across several platforms. It covers late‑90s and early‑2000s pickups and SUVs that used this belt configuration, making it suitable for common repair and maintenance jobs.

• Fits Toyota Tacoma 3.4L V6 from 1995 through 2004.
• Compatible with Toyota 4Runner 3.4L V6 (1996–2002).
• Compatible with Toyota Tundra 3.4L V6 (2000–2004) and T‑100 3.4L V6 (1995–1998).

What sizes and part numbers are included in the kit?

The package brings together three commonly used belt lengths and cross‑references to several aftermarket and OEM part numbers so you can confirm fitment before installation. These belts replace the most frequently needed front accessory drive sizes for the listed vehicles.

• Includes belts equivalent to lengths 4PK870, 4PK1050 and 4PK1070.
• Cross-references: K040343 / 5040345 / 343K4; K040413 / 5040413 / 413K4; K040421 / 5040421 / 421K4.
• Sold as a three-belt set to allow synchronized replacement of all drive belts.

How are these belts built and what performance can I expect?

Each belt is manufactured from flexible rubber compounded with reinforcement fibers for strength and heat resistance. The construction aims to maintain steady pulley engagement under vibration and temperature cycles encountered in daily driving.

• Reinforced elastomer body resists cracking and stretch.
• Designed for stable operation of alternator, A/C compressor and power steering pump.
• Reduces risk of premature failure compared with a single worn belt replacement.

Why buy the three-belt kit instead of replacing a single belt?

Replacing all front accessory belts at once restores balanced tension across the system and prevents mismatched wear patterns that can lead to noise or component strain. A full kit saves time and helps avoid repeat trips to the garage for closely timed belt failures.

• One purchase covers the entire accessory belt set for the front drive assembly.
• Minimizes labor by allowing simultaneous belt replacement.
• Helps maintain uniform tension and pulley alignment after service.

Who is this for: This Mhrxusd belt kit is aimed at DIY mechanics, fleet maintainers and repair shops working on Toyota 3.4L V6 vehicles from 1995–2004 who want an economical way to replace all front accessory belts at once. It’s also useful for owners preparing a vehicle for long trips or restoring older trucks and SUVs where belt age or cracking is visible. Verify vehicle year, engine code and pulley layout to confirm fit before purchase.
