AMC JEEP 4.0 4.2 1.7 Ratio "Adjustable" Light Weight Roller Rocker Arm Kit
If you want dyno proven hp & tq gains then here's one of the easiest ways to add 10hp/15ftlbs. This is our new lightweight 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.

Jeep AMC 4.2 258 Stroker Long Snout "Black Anodized Billet Crank Spacer"
If you are running an early 258 (4.2) non-serpentine crank for your Stroker you will need to either cut the crank snout or simply run one of our new "Black Anodized Billet Crank Spacers". These are designed to work with stock and aftermarket harmonic balancers, reuse your stock "Thick" crank washer and make sure your stock bolt has enough thread engagement. ***Attention, the O.D(Outer Diameter) was based off a neutral size so they would fit most all balancers though some balancers will be tighter than others due to inconsistences of manufactures.
Jeep 4.0 Valve Cover Perimeter Grommet 7075 Billet Retainer Set(15 piece).
Jeep made a great simple sheet metal valve cover design that does exactly what it is supposed to do which is: Not leak, Control oil splatter, Proper PCV control without excess oil consumption and acceptable looks. Mopar stopped making these retainers over 10 years ago so we answered another call and made them look even better! Our new 7075 Aircraft Aluminum Retainers are super lightweight, fit even better than factory and can be polished to a mirror finish or powder coated to your liking. These will work directly with our valve cover spacer/stud/bolt kit and our billet thermostat housing to clear that added height. ***Note*** This set will include (15) Machined Billet Retainers.
"HIGH OCTANE" Jeep 4.6 Stroker Engine Package
For those who want the stoutest most reliable street Jeep stroker available on the market that still retains factory manners and dependability as long as you don't mind running premium octane fuel hence the name "HIGH OCTANE" then this one fits the bill. We have done our research and developed an elite engine package that utilizes our custom made hypereutectic pistons and lightweight rings with the highly desired 6.125" (Long)rods, 10.5:1 compression with our newest designed competition head for this piston design. You may ask why Hypereutectic pistons and not forged? For a naturally aspirated engine that see's daily driving and hot rodding in all types of weather you can not beat a well designed Hypereutectic for quiet operation, excellent long life, anti-scuffing and sealing ability. To this point there has not been a hypereutectic option with a 6.125"(Long) rod option so we made one and created a new animal. From the factory the original 4.2(258) started life around 100hp to eventually topping out around 190hp by the 4.0(242). "HIGH OCTANE" at 4.6 liters is another animal all together, on our dyno this package pumped out 366hp and 373ftlbs of torque with one of our less aggressive cams. With this package we can custom tailor the cam to suite your needs and bring the power in where you want it. This package will have all of our goodies such as: 1.7 adjustable roller rockers, 3/8" pushrods, billet valve cover spacer kit w/billet valve cover perimeter retainers, billet thermostat housing, ATI serpentine damper kit, slicked out paint color of your choice, intake block-off plate, water pump, copper intake/exhaust manifold gasket, stainless steel winged washer kit, 24lb injectors. Recommendations: Intake/Intake/Intake did we say Intake, to totally utilize this package we recommend an extremely ported stock intake manifold or custom setup(Sheetmetal) with an oversized throttle body(These are not mandatory items just recommended), header with 3" collector and a custom tune is MANDATORY with 91 octane minimum. Manual transmissions require clutch upgrade such as Mcleod or Centerforce. Automatic transmissions say a prayer then prepare for a moment of silence unless built or shift kit(Except AW4's, if they are healthy they seem to hold up well).
***BUNDLE PACKAGE*** Extreme Duty Copper Intake/Header Gasket & 500"(1/2") Stainless Steel Winged Washer kit.
We heard your request so we added a BUNDLE PACKAGE for our very popular "Copper intake/exhaust gasket" and "Stainless Steel Winged Washer/ARP bolt kit". With this option you will save $7.00 off the total of both items and only shipping costs will be applied for one item, typical savings average around $31.00 when bundled.
