SLP magnum force weights loaded at 69.2 grams, yellow venom 120/340 drive spring, and a venom blk./grn. 140/220 driven spring. if you really want it to go?

the thing with any adjustable weights is in the warmer spring riding temp's just remove a screw or two and bring your rpm's right back. the 2017 assault needs to spin @ 8350 rpm for peak performance.

we found SLP weights to out perform daltons down low. by length every time to 300'. up top there about the same. we feel they have better belt squeeze down low.
