Jeep AMC 4.0 4.2 Revised Billet Aluminum Thermostat Housing 1971-2006
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 that fits all years 1971-2006. We offer this housing in Raw or Black Anodized.
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(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.
Billet Valve Cover/Roller Rocker Spacer Kit
This is the most advanced and complete Billet Valve Cover/Roller Rocker Spacer to date. This spacer kit has a proprietary designed doweled/interlocking system to keep everything aligned for proper fitment, sealing and to squeeze in those big 1.6 or 1.7 Adjustable Roller Rocker Arms. This kit is designed retain the factory valve cover and its excellent breather/baffling system which most aftermarket covers DO NOT HAVE. Items included in this kit are the following: 5/8" Billet valve cover spacer(96-06 style valve cover), locating receiver dowels(96-06 12pt head bolts suggested not required), two black usable locating rubber valve cover gaskets, valve cover perimeter grommets, valve cover breather and PCV fittings w/grommets, Stainless Steel button head perimeter bolts or Stainless Studs w/Nylock nuts and AN washers to finish off everything so there's no rusty crusty looking mess down the road.
.500"(1/2") Stainless Steel Intake/Exhaust Flange Winged and Round Pinch Washer kit w/ARP 12pt Stainless Steel bolts.

This newly designed Winged 1/2" Polished Stainless Steel washer can be rotated to fit multiple locations or reach the intake casting that the factory round washer could not quite reach before and has enough bore clearance to allow the washer to articulate on uneven surfaces.
