JMX PRO Rod End for the Ultimate in Strength and Longevity. 

 These rod ends are the best way to add strength, reliability, and flexibility to any situation that requires use of a rod end such as in suspension or steering applications. The JMX series utilizes a high strength Heat treated 4130 Chromoly body with a silver zinc finish with a smooth PTFE (Teflon) liner for smooth operation. The ball is made from heat treated bearing steel for strength and hard chrome polished for a smooth surface. The race is a heat treated alloy steel which means this joint will outlast a normal budget rod end with injection molded race. The JMX series with Teflon lining keeps the joint quiet and tight for years and years of usability.

🧾 Rock Rig Supply Return Policy

At Rock Rig Supply, we get it — sometimes a part just doesn’t fit the build, or a project takes a left turn halfway up the hill. We’ve been there. That’s why our return policy keeps things simple, fair, and flexible (because real-world wrenching isn’t always perfect).


🕒 1. Return Window

  • Returns are accepted within 30 days of delivery.

  • Items must be unused, uninstalled, and in original condition with all packaging.

  • Every return gets inspected before we process it — we don’t cut corners, and we don’t want you to either.


🔧 2. Custom & Built-to-Order Parts

  • Custom, one-off, or built-to-order parts carry a 50% restocking fee.

  • They’ve been made just for you, so we can only take them back if they’re unused and still in sellable shape.


💰 3. Refunds & Store Credit

  • You can choose between a refund or store credit after your return is approved.

  • Some items may have an additional restocking fee depending on condition.

  • Refunds typically appear 7–10 business days after approval, depending on your bank.


🚚 4. Return Shipping

  • If we messed up (wrong item, damaged, or defective), we’ll cover return shipping and send you a replacement on our dime.

  • If it’s a “changed my mind” or “wrong fit” situation, you’ll cover return shipping.

  • Not sure which way it goes? Shoot us an email at rockrigsupply@gmail.com and we’ll help you sort it out.


⚙️ 5. Used or Installed Products

We know how it goes — sometimes you bolt something up and realize it’s not gonna work.
If the part’s been used or installed, email us first at rockrigsupply@gmail.com.
Returns for used parts are handled case-by-case at our discretion because we understand that not every project goes as planned.


🧰 6. Garage Sale Items

Our Garage Sale section is full of awesome deals — open-box, blemished, and used parts that still have plenty of life left.

  • All Garage Sale items are sold “as-is.”

  • No returns, refunds, or warranties on these.

  • We do our best to describe the condition, but little quirks or wear come with the territory.
    You’re scoring a deal, and we’re clearing the shop — win-win.


🔄 7. Exchanges & Buy-Backs

  • Unused, uninstalled items qualify for free exchanges or store credit.

  • If a part’s been installed or opened, we may offer a buy-back depending on its condition and resale potential.


🚫 8. Non-Returnable Items

  • Gift cards, Garage Sale items, and consumables (fluids, sealants, etc.) are non-returnable.

  • Items missing packaging or showing heavy use may be denied or refunded at a reduced rate.


📬 9. How to Start a Return

  1. Email rockrigsupply@gmail.com with:

    • Your order number

    • Photos (if damaged or defective)

    • A short note about what’s going on

  2. We’ll reply with return instructions or a prepaid label (if applicable).

  3. Once inspected, we’ll issue your refund, store credit, or exchange.


💪 10. The Rock Rig Guarantee

We actually run the parts we sell — they’ve been hammered, flexed, and tested on real trails. If something doesn’t hold up or doesn’t meet your expectations, reach out. We’ll make it right, because that’s how we’d want to be treated.
