This (2007 and later) Iron Horse specific shock hardware adapter kit answers the question, "How do I use your needle bearing (or DU Bushing) kit on my Iron Horse frame with 10mm existing hardware?" This adapter kit includes all the hardware you need to mount either our Needle Bearing Kit or DU Bushing Kit for 30mm mounting spans on the following 2007 and later Iron Horse frames:

-MK III (Top and Bottom Compatible)
-6 POINT (Top and Bottom Compatible)
-7 POINT (Top and Bottom Compatible)
-SUNDAY (Top Compatilbe)

For those frames that are both top and bottom mount compatible, a needle bearing kit is recommended for the top, with a DU bushing ki recommended for the lower mount. This is because the upper rocker arm mount has a great deal of rotation inside the shock eyelet, while the lower mount has almost no intra-eyelet rotation in the shock.
