Edelbrock shocks have a unique patented valve system known as the Inertia Active System (IAS). Their Jeep Shock range has been designed and tuned to suit each particular Jeep model. In addition if customers want to comtomise their Edelbrock shocks to meet specific valving, length or design requirements this can be done by the Australian Edelbrock appointed Engineering Centre For Edelbrock Shocks at Suspension Technology Australia’s (STA) engineering workshop.

STA has built custom IAS piston shocks for the likes of Craig Lownes, Greg Carr & Peter Brock. Peter Brock runs them on his Targa Monaro and his team brock driver training cars. This product meets the high standards he call for and he has endorsed the product. Peter say’s ‘it works’.



Detailed below is some information about shock absorbers and points to consider when purchasing shocks to ensure you obtain the best performance out of your Jeep. We recommend you take the time to visit the Edelbrock shock website.

Basic Information:

A shock basically helps keep a vehicle’s suspension under control in order maintain handling & traction:

• When doing this shocks oscillate up (compression) and down (rebound) with road conditions ie bumps & potholes,

• Compression & rebound is controlled by the shocks piston moving internally through the oil in the cylinder,

• This constant oscillation creates heat and eventually shock fade therefore the quicker a shock can dissipate heat and react to road conditions the better the vehicles performance.

Therefore:

• Superior designed shocks do this more effectively and efficiently

Monotube advantages:

• They have an internal floating piston to divide the nitrogen from the oil, this helps prevent the piston from creating a foaming mixture of nitrogen and oil inside the shock cylinder and therefore creating shock fade (failure),

• They dissipate heat more efficiently because the cylinder or shock body is the component that contains the oil, this allows the air to come into direct contact with where the heat is being dissipated and provide superior cooling. This is unlike twintubes where the pressure tube, where the friction and heat is generated is insulated by an outer tubes diminishing heat dissipation. This unique ability of the monotube enables the shock to sustain demanding conditions for longer;

• They have larger more efficient pistons ensuring that they react faster & more effectively to road conditions. Therefore the vehicle will remain stable, maintain traction and performance.

• Through valving we can control the shock absorbers characteristic under certain conditions ie how the way in which the shock behaves at different shaft/piston velocity (speed the piston moves through the shock cylinder). For example the valving can be tuned to be very stiff in compression at slow shaft/piston velocity (ie to stop body roll) or soft at fast shaft/piston velocity (efficiently absorb speed bump at 60kph).

• 95% of the worlds race cars, rally cars & offroad racers run monotube design shocks which is no coincidence

Ok now we know that if you want better performance from a shock your best bet is to run monotube shockabsorbers. There a several top mass produced monotube shocks available for 4x4s. And for the last 40 years every company has been trying to copy and produce their own variant of the ‘Decarbon’ deflective piston design.

Well at least until the Ricor IAS piston design came out and was patented several years ago. This new piston is called Inertia Active System (IAS) and has set the standard for shockabsorber design and performance for the next 20 years. This design is now owned and run in Edelbrock performance monotube shockabsorbers.

Without detailed description, this new piston design enables the shock to be more responsive than other mass produced piston on the market. It has no competitors because there is no shock & piston combination in same price range that is as efficient, effective or has the ability to control heat and sustain performance.

The IAS design main advantage occurs under rebound. Normally the piston would be pushed/forced through the oil by the action of the main vehicle spring returning to it’s normal height after compression. This rebound motion creates heat as the oil squeezes through the holes and valves on the piston.




• However with the IAS piston design under the same conditions, the piston does what Edelbrock call a full bleed. This in basic terms means the piston and shaft will free fall faster than a standard monotube or twintube and with limited force & friction from the oil passing through the piston. This free fall in addition to being quick in response it also reduces heat generation up to 60%.

• So what does this mean for your Jeep, well you get superior performance & traction than any other shock available on the market in the same price range and in many circumstance better than other more expensive products.

• Eg Imagine you are traveling down a dirt track and suddenly your front wheel drops into a pothole, normally not only does the front wheel fall into the pothole but the chassis drops down too!!! Therefore transferring this bump through the vehicle and the steering and as such makes the vehicle unstable. However in this circumstance the IAS shock reacts instantaneously only letting the spring push the wheel into the pothole while the chassis remains at ride height with full handling and stability. The bigger the hole or obstacle the greater the performance effect the IAS shock will provide.

Send us some freebies Sean and I will test them for you!

weve had those for a while, like about 8 yrs even but they have never taken off. teraflex once loved them but...good luck whoever takes them on.

The RubiconExpress shock is an Edelbrock shock built to RE's specifications ~ painted grey Much like the OME unit is Monroe built to OME specifications. Never really moved many due to being a monotube.

I run the Edelbrock Xtreme (remote cans) with IAS snake oil inside on the Goatsack TJ.

IMHO they're pretty much a world apart from the Rancho 9000's (expertly fitted by the guys at USA4x4) they replaced. The Rancho's served me very well for several years and when retired (sold still working) they were very battered and bruised but still in one piece. The IAS of the Edelbrocks has essentially taken over the role of the 5-speed in-cab adjuster of the Rancho's with the added advantage that it's always on the right setting without you worrying about it...if that makes sense ??

The Edelbrocks were to serve the new long arm suspension as they match the travel of a TJ 6" lift. They do everything they say they do from my experience and I would recommend them to anyone look for a high performing reliable shock.

According to the experts (eg ABT4x4's partner in crime John at Suspension Technology Australia) the Edelbrocks run a *lot* cooler for speed work like fast 4x4 events ie OBC, rallies, offroad racing, etc as they constantly adjust the valving to reduce heat.

I got to smell a cooked Koni's oil at John's test bench and it smells well rank (bit like rancid Goat faeces) after being pounded in a Rally car the heat built up enough to cook the oil !

John advised the Edelbrocks IAS gizmo keeps heat about a third that of similar high-quality mono's under extreme use. He doesn't speak with just internet wisdom either as his $30000 shock testing machine gives the results in pages of computerised detail to help him tune these shocks to bits of kit like Brockies offroad racer Jackeroos, Hyundai's Terracan OEM shock upgrade option and even some of DOD's tanks (!!).

These babies are rebuildable by a qualified shock builder too. Internal IAS spring rates and oil weights can be tuned to your vehicle and spares are available for not too much. (I know !! a Jeep-related part not costing too much ! I nearly fainted...).

Pre-spring retainer days when my spring dropped out at a winch comp and snapped off my remote shock can line it was repaired with easily found bits from Enzed and repressurised and resealed by John.

I understood about 1/8th what he explained but just enough to realise the heat difference was HUGE and the auto valving of the IAS actually worked.

Good enough for me
