IRWIN FITNESS ROLLER J-CUPS 2.0

Introducing our game-changing Return Roller J-Cup – a home gym essential crafted with precision and innovation. Your barbell experience is about to be revolutionized with our specially designed machined rollers, ensuring that your bar finds its way back to the center position effortlessly every time.

Composite Plastic vs Metal: Boasting three times the tensile strength of UHMW with similar wear properties, our rollers are built to withstand rigorous use by utilizing machined acetal plastic. If you don't fancy ever having to swap out the composite rollers you can opt for our hardened metal rollers. Starting as a 2" metal shaft, machined to perfection, our rollers undergo an electroless nickel phosphorus bath for an attractive, durable finish. Heat treatment results in a remarkable hardness rating of ~900 VHN, surpassing regular stainless steel.

Center Return Roller: Tapered towards the center, our rollers accept all bar sizes, including specialty bars. This feature ensures adaptability and convenience for a diverse range of workouts.

Flat Roller: Our flat set of rollers is thoughtfully crafted to cater to those who prefer positioning their barbell in the front or back of the j-cup before lifting the barbell off. Think of pushing your barbell either forward or backwards to prepare for a lift. This design ensures consistency and accuracy in your setup for every lift.

A little known fact about our roller j-cups is the ability to use the 5/8" or 1" hole at the bottom of the roller j-cup allows for the use of magnet or detent pins to secure the j-cup. Although they are often unnecessary due to the secure fitment of the roller j-cups.

Personalize your setup by specifying your preferred custom color in the notes section at checkout. We strive to match your choice accurately and will contact you if needed.

Tolerance/Fitment: Expect a fitment tolerance of +/- 1 mm due to the solid piece clasp (not welded), ensuring a secure and reliable hold. We are able to swap out plastic components to fit better on metric racks. However we are not guaranteeing a snug fit like we aim to achieve on true 3"x3" racks. Leave a note at checkout specifying rack fitment.

IMPORTANT NOTICE U.S / CANADA SHIPPING

New 50% Metal Tariff (Effective Immediately)

Due to recently implemented U.S. import tariffs, all Irwin Fitness orders shipped to the United States are now subject to an additional charge.

  • Approximately 70% of your total order value reflects the metal content.
  • A 50% tariff is applied only to that metal portion.
  • In simple terms, the tariff equals roughly 35% of your total order value.

This fee is set by the U.S. government and collected on import. We do not profit from it — it is strictly a pass-through cost.

Shipping to the U.S.

We now ship nationwide across the United States using Delivered Duty Paid (DDP) service — meaning no surprise fees on delivery.

  • Flat Rate Shipping:
    $650 CAD / $478 USD for LTL (less-than-truckload) shipments to U.S. terminals
  • Includes all broker and bond fees
  • Rate applies to terminal pickup only (customers are responsible for home transport)
  • Orders typically arrive at terminals faster than residential deliveries.

Residential Delivery:

Available upon request before checkout (a surcharge applies).

Customs & Documentation

We handle all brokerage through Noatum Logistics, or you may use your own U.S. Customs Broker.

For LTL shipments, an IRS or SSN number is required for clearance (not needed for UPS).

All shipments are subject to state taxes and U.S. Customs fees; Irwin Fitness does not collect or retain these charges.

Canadian Shipping

We strive to secure the best possible freight rates across Canada.

If you live in a remote or rural area, additional delivery charges may apply. You’ll be contacted before your order ships and can either approve the extra cost or receive a full refund.

Simply the Best

Best purchase I’ve made for the home gym

They're beautiful!

They're beautiful. It even hurts for me to use them. One thing though I wish they would offer the overseas 3x3 rack measurements. They are slightly smaller than the true 3x3, so they fit a little loose on my rep rack.

Perfect

The J cups are exactly what I wanted, the fitment on my rack is tight. The paint quality is incredible!

My only complaint is I wish they came with magnetic pins at this price point.
