Mathews Phase 4 Mod Chart

Need to order a new set of Mathews Phase 4 draw mods? Use our helpful Mathews Phase 4 mod chart below to identify the set of mods that match your draw length.

The Mathews Phase 4 was released in 2023, and was available in 29 and 33 ATA length bows. Aptly named the Phase 4 29 and Phase 4 33 to designate the overall length, this was Mathews’ flagship bow for the year.

Built around the CrossCentric cam system like Mathews bows of previous years, the Phase 4 also boasts innovative accessory attachments with their Bridgelock system. Both versions of the Mathews Phase 4 are the most technologically advanced hunting bows Mathews has produced to date.

The Phase 4 SwitchWeight mods adjust the Draw Length, Draw Weight, and Let-Off. Simply swapping a cam module with two allen bolts. With that many combinations available, the Mathews Phase 4 Mod Chart can appear overwhelming. We are here to help you find the right Switchweight mod for your Mathews bow.

The Mathews V3X 33 and V3X 29 are still in the Mathews Archery lineup for 2023. Hopefully if you’re purchasing a new bow it came from the dealer with the correct draw mods. If you purchased a used Mathews V3X, you may need to change the draw mods to fit your draw length. Thanks to the SwitchWeight mods you can also easily change the draw weight without changing the limbs. No need to use a bow press to disassemble your compound bow.

The charts below show which draw mod you need to order for your Mathews Phase 4, the ultimate hunting bow.
