1.7 "Adjustable" Lightweight Roller Rocker Kit AMC JEEP 4.0/4.2 "Next Generation."
If you want dyno proven hp & tq gains then here's one of the easiest ways to add 10hp/15ftlbs. This is our next generation, even lighter weight, yet heavy duty 1.70 ratio adjustable roller rocker arm kit. These are 100% made in the USA and feature a heavy duty fully rollerized fulcrum and roller tip. *3/8" .080" wall pushrods can only be used only on our competition heads unless you clearance your head accordingly. On most roller rocker arm kits and especially on adjustable kits you will have to space the valve cover up at least 1/2' for clearance from the added height of the over-sized rocker arms. We offer one of the best solutions for this issue with our 5/8" Billet Valve Cover Spacer Kit which is also listed on our site.
