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(maybe). Engine builds are running 2-3 months out as of 5/7/21 once order is placed.
***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.
Jeep AMC 4.0 4.2 Revised Billet Aluminum Thermostat Housing 1971-1999
Is it time for a new thermostat housing due to pitting, breakage, leaks, maybe after you add that new valve cover or spacer kit for those new roller rocker arms and now the thermostat housing hits or you just want the best damn housing on the market period then this one is for you. We have totally redesigned the AMC Jeep thermostat housing correctly with corrected outlet angles and solid billet aluminum construction. We offer this housing in Raw or Black Anodized. ***This housing only fits 1971-1999 4.0 and 4.2 engines, the 1999 and newer front drives may have a belt interference issue if your front drive has an idler pulley on the front side of the head. You can still use this housing but you will need to clearance the bottom area accordingly***
