Martin Limb Numbers

[Nomad59]

I've read different treads on the subject here and on AT. What do the #'s mean? 5L, 5H, 4L... I read on one post that the letter means L-low, M-med, H-high. I have 5L on my 09 Cheetah 55-70 DW 29 DL. Does anyone really know how the number-letter system works?

The combination of a number and a letter gives you the information about the limb deflection. With Elite Archery you have a number of three digits, with Martin you have this combination.

Each combination is possible and each combination leads to a different draw weight on one bow. But 5L on a cheetah for 70lbs do not mean that you can get 70lbs with a 5L limb out of a MOAB and so on.

Every number stands for a step of 5 lbs upwards or downwards.
This means:
4 - 65 lbs max
5 - 70 lbs max
6 - 75 lbs max

Every letter stands for a difference of 2-3 lbs.
This means:
5L - 70 lbs max
5M ~ 72 lbs max
5H ~ 75 lbs max

Every number stands for a step of 10 lbs upwards or downwards.
This means:4 - 65 lbs max
5 - 70 lbs max
6 - 75 lbs max

Every letter stands for a difference of 2-3 lbs.

5L - 70 lbs max
5M ~ 72 lbs max
5H ~ 75 lbs max

5 lbs. not 10 lbs.

Sure.

As you can see it was just a mistype in the sentence. The example is still right.

[Nomad59]

Now it makes sense. This should be a sticky!

[Nomad59]

So if I wanted to order 60# max limbs for my Cheetah I would ask for 3L right? And would I need to change anything else?

Absolutely.

Nothing else to change. Just the limbs.

So, what would it mean to switch out 2H limbs on a 08 LH Martin Firecat to 6L limbs from an 08 Martin Leopard and could it be done?

[bfisher]

No reason why it couldn't be done. Use the math you've been shown here. Your 5L limbs are 55-70. 6L limbs would be a 5# step up so the bow would become 60-75#.
