Product Info

Product Info

EZ Lynk 4WK To Lifetime Upgrade is organized to make fitment, included components, and ordering details easier to confirm.

Confirm the listed year, make, model, engine, and any truck-specific configuration before purchasing. Review the available Builder selections before ordering. The exact contents and fitment depend on the options selected on this product page.

How to Choose Your Options

  • Tune provider: This selection chooses the company or calibration writer that supplies the custom tune: Unlimited Diesels, Proven, GDP, CCS. It does not change the truck’s physical fitment or exhaust hardware by itself.

This Is a 4wk to Lifetime tune pkg ONLY. You will already have to have a 4wk tune pkg from us already in order to upgrade to lifetime. If you don't already have a 4wk tune pkg from us or one of the tuners we offers tunes from we will invoice you for the difference. No refunds on this!

Fitment and Ordering

Match the product to the year, make, model, engine, and truck configuration shown in the title and product options. Available selections may include Builder.

Installation Notes

Compare the received parts with the listing and confirm fitment before beginning installation. Professional installation is recommended when vehicle-specific access or modifications are required.

Fitment and Options

Options on this page are tied to real Shopify variants. Unavailable combinations are disabled automatically, and the cart receives the exact selected variant.

Unlimited Packages, tuners, and tunes require a decoded 17-character VIN before checkout. The VIN and verified vehicle are saved separately from your modification notes.

Bundle pages can add matching support parts with the main product. Exhaust, EGR, tips, intakes, switches, and support parts are grouped so the order stays clean.

Shipping

Shipping options and delivery times are shown at checkout. Fast air shipping may be available at checkout. Some tuning, custom-order, and VIN-matched items may require extra processing time.

Returns

Electrical, tuning, special-order, and used/installed items may have special return limits. Contact support before ordering if you are unsure.
