Upgrade Your Drivetrain: The HD U-Joint for 2014+ Honda Rancher / Foreman / Rubicon

When you’re pushing your machine hard — larger tires, gear reductions, steep terrain — it’s not just the motor that takes the beating. Your drivetrain sees serious torque, side loads, and shock impulses. That’s why the “weak link” often ends up being the factory U-joint. With the heavy-duty U-joint upgrade from Terache (available through Vessel Powersports), you get a robust solution designed for the kind of abuse stock parts weren’t built to handle. 

Why It Matters

Factory U-joints are designed for stock conditions. But when you add oversized tires, gear reductions, or hit tougher terrain, the loads and angles change. The product listing explains:

• The HD U-joint is +75% larger than OEM, delivering substantial strength and durability. 

• Built to handle the extra torque from those mods. “Stop breaking OEM U-joints,” the listing puts it. 

• Precision-machined, heavy-duty steel alloy construction with a corrosion-resistant finish.

• Direct replacement for the OEM part: replaces OEM #40300-HR3-A20 for a perfect fit. 

In short: if you’ve upgraded your machine, the stock U-joint is one of the first things you should upgrade too.

Fits These Honda Models

This upgrade is specifically designed for the popular Honda ATV platforms:

• 2014+ Honda Rancher 420 

• 2014+ Honda Foreman 500 

• 2015+ Honda Rubicon 500 

• 2020+ Foreman 520 and Rubicon 520 also included. 

If your machine matches one of these fitments, then this upgrade is plug-and-play [mostly] and built to handle your next level of performance.

Key Features & Benefits

Let’s break down what you’re getting and why it’s worthwhile:

1. Oversized Construction (+75%)
That extra size means more metal, better load distribution, and less flex or fatigue under harsh loads. It’s a serious upgrade. 

2. Heavy-Duty Alloy Steel & Corrosion-Resistant Finish
Built for long life, not just a “trail hero” part you replace after one season. Durable finish means it stays strong. 

3. Designed For Bigger Tires & Gear Reductions
If you’ve done mods such as larger tires, lift kits, gear reductions, you need drivetrain parts that match those changes. This U-joint is aimed directly at those riders. 

4. Direct Replacement Fit
No guessing which joint fits. It replaces OEM #40300-HR3-A20 for a direct fit. Installation is straightforward. 

5. Prevents a Common Failure Point
Drivetrain failures are trail killers. A broken U-joint means downtime, expense, possibly stranded. Upgrading removes one of the weak links in your build. 

Installation & Rider Tips

Here are a few pointers to get the most out of this upgrade:

• Before installing: clean the surrounding area, inspect drive shafts, splines, any signs of wear or looseness.

• Use a proper torque wrench and follow any Honda or aftermarket spec — a tight, correct install matters.

• Note: due to the increased diameter of this U-joint (+75% vs OEM), some machines may require minor trimming of the plastic skid plate. The listing mentions this as a possibility of clearance.

• After install: test under moderate conditions first to ensure everything is happy (no unusual vibration, binding, or clearance issues).

• If you’re running bigger tires, lifted suspension or gear reduction — keep an eye on the U-joint periodically for play or wear. Upgraded doesn’t mean invincible, but you’re ahead of the game.

Final Thoughts

If you’re serious about building a trail-ready, aggressive machine on your 2014+ Honda Rancher, Foreman or Rubicon, don’t overlook the drivetrain. Upgrading the U-joint may not be the flashiest mod, but it’s one of the most critical. The Terache HD U-joint offers a proven, heavy-duty solution built to last, handle bigger tires, more torque, and tougher trails.

Don’t wait for a U-joint failure to leave you stuck. Upgrade now, ride harder, and keep your machine strong from the ground up.
