Check out our special intro pricing on our shaft rocker set up on E-bay. Kit is 100% made in the USA of the finest materials and craftsmanship. With the rockers able to handle 850lbs of spring pressure on the nose, they are right up there with the best in the world. Compare these to other common shaft rockers on the market like Cranes Sportsmen series for Small Block Chevy. They say do not exceed 650lbs of spring pressure and cost $800.00 in the Summit catalog and that is for SBC. Imagine how much they would be if they made them for AMCs. Similar quality rockers cost well over $1000.00 a set. A good stud mounted roller rocker, stud girdle and guide plates will run you about the same as my shaft system and be now where near the strength and valve train stability not to mention the hp it robs from your engine compared to a shaft rocker. These were designed and built specifically for AMC not some other brand that was modified to fit our engines and will work with most of the aftermarket and all factory AMC 290-401 heads http://cgi.ebay.com/ebaymotors/AMC-AMX-Javelin-Rebel-shaft-mounted-roller-rockers_W0QQcmdZViewItemQQcategoryZ33624QQitemZ8039143929QQrdZ1QQsspagenameZWDVW If the link doesn't work, the item number is 8039143929 Thanks, Nick Alfano Alfano Performance 262-942-8271 262-308-1302
