Quick Answer

If you need to replace parts on your SizeGenetics traction device, focus on the specific component that shows wear. Use the Keys to adjust the elongation bars, the Complete Right Arm for the Value Edition as a direct replacement, and the Custom Velcro Strap for comfort and tension control. Always match parts to your device version to ensure proper fit.

Understanding the parts of your traction device is the first step to keeping it in working order. Whether you're replacing a worn strap or adding a spare arm, knowing what each component does helps you buy the right replacement without guesswork. This visual guide walks through the most common parts and how they fit into your routine.

Traction device parts work together to apply consistent, comfortable tension. When one part fails, the whole system can slip or lose effectiveness. Recognizing the role of each component—from the Cradle Component to the elongation bars—allows you to troubleshoot and fix issues quickly.

The Core Components of a Traction Device

Every traction device relies on a few key assemblies: the cradle (which holds the glans), the base ring or support, and the arm system that connects them. The arms are the rods that extend to control length, and they are adjusted by adding or removing elongation bars. The straps and padding ensure a secure grip without cutting off circulation.

When you look at a parts diagram, notice how the right and left arms are mirror images. If one side is damaged, you need the correct side-specific replacement, like the Complete Right Arm for the Value Edition. Using the wrong side or a universal arm can misalign the device and reduce comfort.

  • Always check the device version (e.g., Value Edition) before ordering arms.
  • Keep spare keys handy to adjust bars without fumbling.

How to Identify Parts Needing Replacement

Common signs of wear include a frayed Velcro strap, a bent or cracked arm, difficulty tightening the elongation bars, or a cradle that no longer holds the head securely. A visual inspection before each session can catch these issues early.

If the strap slips, the padding is probably worn or the strap has lost its grip. If the bars won't stay in place, the keys may be stripped. Replacing the right part saves time and prevents injury from an unstable device.

Decision Rules for Common Replacements

Use the Keys (set of 2) when you need to add or subtract elongation bars. They are specifically designed for the SizeGenetics device, so they fit the bolts correctly. If you're missing a key, don't substitute a household tool—it can strip the bolt head.

Replace the right arm with the Complete Right Arm for the Value Edition if your current arm is bent, cracked, or no longer holds tension. This part is a direct replacement, meaning no modification is needed. For any other version, check compatibility before ordering.

The Custom Velcro Strap is your go-to when the original strap has lost elasticity or you need a better fit around the support. It combines a plastic support, protection pad, and strap, allowing seamless tension adjustments without pinching.

Decision Rules for Replacement Parts

  • Missing or damaged keys?: Order a Keys (set of 2) immediately. They fit the SizeGenetics elongation bar bolts exactly. Do not use improvised tools. Check your key condition monthly.
  • Right arm bent or cracked?: Replace with the Complete Right Arm for Value Edition if you own that version. Confirm your device version first, then order the side-specific part. Inspect arms for hairline cracks during cleaning.
  • Strap slipping or worn?: Upgrade to the Custom Velcro Strap for a more adjustable and comfortable fit. It includes the protection pad, so you replace two elements at once. Test strap grip before each use.

Genuine Replacement Parts at a Glance

  • Keys (set of 2): These Keys (set of 2) are designed for use with your Sizegenetics penile traction device. They allow you to tighten and loosen the elongation bars when adding or subtracting bars to customize your length setting. Having a spare set ensures you never get stuck mid-session when a key is misplaced. They are the only tool that fits the bar bolts securely.
  • Complete Right Arm for Value Edition: This is the complete right arm for the Value Edition of your Sizegenetics system. It is designed to serve as a direct replacement or spare part to help maintain the functionality of your device. If your current arm is damaged, this drop-in replacement keeps your device symmetrical and functioning without needing extra parts.
  • Custom velcro strap: Custom Velcro Strap Set of: Front piece slot, Velcro fastening for precise pressure and protection pad. A combination of the plastic support, Protection Pad and a velcro strap, allowing you to use seamless adjustment of the tension. Upgrading to this strap gives you more precise control and better skin comfort, reducing the risk of slippage and chafing.

Fit Guidance

Best for

  • Users who own a SizeGenetics Value Edition and need a direct arm replacement.
  • Users who frequently adjust elongation bars and want a spare set of keys.
  • Users who want a more comfortable, adjustable strap with a built-in protection pad.

Not for

  • Users with a different brand of traction device—keys and arms are SizeGenetics-specific.
  • Users who have a non-Value Edition device and need a left arm (this guide covers the right arm only).

Identifying and replacing traction device parts doesn't have to be confusing. Keep spare keys and straps on hand, match arms to your exact device version, and always inspect parts for wear. With the right components, your traction routine stays effective and comfortable.
