Learn how to combine the elongation bar and springs for custom tension, adjust your SizeGenetics device safely, and achieve optimal traction with comfort.
Customizing the tension on your penile traction device is key to a comfortable and effective routine. The elongation bar and springs work together to let you fine-tune the stretch to your body's needs, whether you're focusing on length or curvature correction. In this guide, we'll walk you through how to use these components safely and get the most out of your SizeGenetics device.
Before diving in, it's important to understand the role of each part. The springs provide the base resistance, while the elongation bar lets you adjust the overall length of the device. By combining them, you can create a tension level that's both challenging and comfortable, avoiding overstretching or discomfort.
Understanding the Elongation Bar and Springs
The elongation bar is a metal rod that connects the base of the device to the headpiece. Its length determines the starting distance between the two ends, which directly affects the tension. Springs, on the other hand, are coiled components that compress and expand to provide a consistent, adjustable resistance. In the SizeGenetics system, you can swap springs of different strengths to increase or decrease the force.
The Penile Traction Device Kit — SizeGenetics® Ultimate System (FDA-Registered & CE-Certified) includes both the elongation bars and springs, giving you a range of options. The springs (set of 2) are available as replacement parts, so you can experiment with different tension levels without buying a whole new device. Understanding how these parts interact is the first step to mastering custom tension.

- Always start with the lowest tension setting and gradually increase.
- Listen to your body: if you feel sharp pain, reduce tension immediately.
Step-by-Step: Adjusting Tension with Elongation Bar and Springs
To adjust the tension, first disassemble the device according to the manufacturer's instructions. Remove the headpiece and the base, then slide out the current elongation bar. Choose the bar length that gives you a slight stretch when the device is worn—this is your starting point. Attach the desired springs, ensuring they are securely in place.
Reassemble the device and put it on. Tighten the adjustment screws gradually, turning them a few millimeters at a time. After each adjustment, wear the device for a few minutes to gauge the tension. The goal is to feel a gentle pull without pain or numbness. If you need more resistance, consider using a longer elongation bar or firmer springs.
- Keep a log of your settings to track progress and find the sweet spot.
- Never adjust the tension while the device is on your body—always remove it first.
Tips for Comfort and Safety
Custom tension is only effective if you can wear the device consistently. To avoid discomfort, ensure the headpiece is properly padded. The Sensitive glans kit and No-slip protect are excellent accessories that enhance comfort and prevent slippage, allowing you to maintain tension without irritation. Using a Protection pad can also reduce pressure on the glans.
Regular cleaning and moisturizing are part of a safe routine. The Accellerate clean disinfectant keeps the device hygienic, while Accellerate cream moisturizer helps maintain skin elasticity. If you experience any soreness, take a break and reduce the tension level. Remember, consistency matters more than maximum tension.
- Use the Comfort package for additional padding and ease of wear.
- Always follow the recommended wear time and consult a professional if you have concerns.
Mastering the elongation bar and springs allows you to customize your traction therapy for better results and comfort. By starting low, adjusting gradually, and using the right accessories, you can create a routine that fits your needs. Remember, patience is key—consistent, comfortable tension yields the best long-term outcomes.
