Refund Policy

60-Day Money-Back Guarantee & Refund Policy

At ProJellico™, we are fully committed to your truck’s longevity and your complete peace of mind. We are so confident in our product's ability to protect your valve train that we offer a 60-Day, 100% Money-Back Guarantee.

If you don’t feel the immediate difference in transmission smoothness, linear throttle response, or the complete elimination of the V8→V4 highway shudder within 60 days, we will refund your order—no hoops, no restocking fees, and no interrogation.

How the Refund Process Works

  • Drive On It: To experience the true benefit, our device is designed to hold your engine in V8 mode full-time. We ask that you plug it in and drive on it consistently across various road conditions—commuting, towing, and highway cruising—to evaluate its real-world performance.

  • Contact Our Team: If you are not completely satisfied with how your truck drives after trying the device, simply reach out to our US-based support team via email.

  • Provide Details: Please include your Order Number and a brief note regarding your vehicle's make, model, and year so we can understand your exact experience and how to improve our architecture.

  • Hassle-Free Processing: Once your request is received, our team will process your refund immediately. You will receive a automated confirmation email, and the funds will be credited back to your original payment method within 5–10 business days.

Important Notes

  • No Need to Return: We know how valuable your time is, and we respect your schedule. In most cases, there is absolutely no need to go through the hassle, expense, and ameleliği of shipping the device back to us. We trust our customers, and your honest engineering feedback is far more valuable to us than a returned piece of hardware.

  • Eligibility: This guarantee is valid for the first 60 days following your purchase date and applies strictly to orders made directly through our official website.

  • Support Limits: Please note that while our device successfully eliminates the commanded collapse cycle, it cannot physically heal a lifter that is already bent, collapsed, or ticking due to existing mechanical damage.

Have questions? We are here to help! Whether it’s about the risk-free refund process or checking your vehicle's fitment specs, please don't hesitate to contact us. Your truck's reliability is our priority, and we’re here to make sure you have the best experience possible.
