Take it to the dealer you purchased it from and have them order you a new limb for the cracked one. It’s a warranty issue and the part will be covered. Your dealer though may charge you labor for the install as that’s not covered by warranty.
Offering a single limb is a great service. This may slightly change my thoughts on Mathews.
I had the same issues with the Traverse (never dryfired!) - and the splinters are not only the dislodging coating, but also fibre. When I removed the splinters the grooves were 1 to 2 mm deep. I got the limbs replaced under warranty, however, the replacements where all marked as pretty much the same strength / spring rate ( 108, 108, 108 and 109) while the genuine ones were 105.5 and 104.5 on the left side, and 108.5 and 107 on the right side. Note that the cable runs on the right side, hence the forces on the right side are stronger than on the left. Having now limbs with approx. the same spring rate on all corners facilitate the cams to lean at full draw (DL = 31") thus moving the string / nock to the right which leads to a flick of the tail / nock to the left when releasing the arrow, hence I get - no matter what I do (top hat tuning ...) a 10 to 15 mm tail left tear when paper tuning. I have a little bit a hard time to get this issue resolved which I believe needs the limbs with the correct spring rate at each corner - the dealer argues that the limbs send by Mathews are the correct ones, but as the spring ratings definitely don't match the genuine ones I don't believe this. Hence the question: can someone here confirm that the left and right spring rates are different? (Note that unfortunately the rating is hand written with a marker on the inside of the limb end, so can only be seen when the limb is dismantled).
....to shim the limbs on the right to add this little bit of additional pre-tension compared to the left. The limbs are sitting in a small module that can be removed from the limb pockets when the limbs are out. Now I cut 2 pieces from the credit card with the exact shape of these modules. The modules have a small pin to locate them, hence the shims made from the credit card need a hole to facilitate that they sit under these modules (which now holds them in place too). Once everything is back together I can just slightly recognize that the right limbs are sitting a tiny tad higher in the modules / pockets. The results: full success - with adding this little bit of pre-tension no flicking the nock to the left anymore, bullet hole with the first shot! ....Mathews doesn’t put heavier deflection limbs on the cable side. They’re all going to be the same deflection rating or very close to it. Hoyts are like this as well. So doesn’t matter what configuration you put them in. This is why they’ll offer you just one limb if that’s all you need. So your dealer is correct.
It has zero to do with cam lean. If it was for cam lean you would see a much larger gap between the deflection number from the cable side to the shelf side than even what your original limbs had. Hoyts are the same as well. PSE is about the only manufacturer I know of that still does higher deflection limbs on the cable side. Any left/right variations can be tuned out using the top hats. I’ve changed a lot of limbs over the years, I mean a lot, so this isn’t my first go around with Mathews limbs.
) so it really doesn't matter for you, but if you do more with your bow you want to have it shooting clinical, precise bullet holes.
