Product Info
Give your LandCruiser 76, 78 or 79 Series rear suspension additional travel and protection with Superior Engineering 2 Inch (50mm) Extended Shackles. Manufactured 50mm longer than the standard shackles, these heavy-duty shackles are designed to suit lifted leaf-spring applications while incorporating an anti-inversion design to help protect your suspension.
The integrated anti-inversion bolt acts as a mechanical limit to prevent the shackle from travelling too far. This is particularly important when reversing into obstacles such as stumps, rocks or steep edges. Under these conditions, the force on the shackle can cause it to rotate beyond its normal operating position, potentially forcing the leaf spring to bend or become damaged. The anti-inversion bolt limits this excessive movement, helping protect the spring and maintain the intended suspension geometry.
The shackles feature greasable pins to allow regular lubrication and smooth operation, while the welded pin design helps prevent the pins from working loose and wearing against the shackle plates. They accept standard replacement bushes, making servicing straightforward when required.
Each set is supplied as a pair for the rear of the vehicle and is manufactured 2 inches (50mm) longer than standard. When fitting older vehicles, we recommend replacing the bushes at the same time, particularly if the original shackles are showing signs of corrosion. Rusted or seized bushes can make removal difficult and may damage the shackle pins during disassembly.
For LandCruiser owners looking for more suspension movement without compromising shackle durability, the Superior Anti-Inversion Extended Shackles provide a practical upgrade designed to handle the abuse that comes with serious four-wheel driving.
Key Benefits
Important Notes
When fitting new shackles, it is recommended to replace the bushes at the same time, particularly if the original shackles have been exposed to corrosion. Rusty or seized shackles can damage the original pins, and fitting new shackles over damaged pins can lead to premature wear of the new components.
Superior Engineering offer custom built suspension solutions, with unique adjustability and performance.
These kits are assembled to order to suit your requirements, with an average lead time that can vary between 1-3 weeks.
If you need a specific eta, please contact us before ordering and we will be sure to assist you.
Consolidated freight allows PPD Performance to combine multiple orders onto a single pallet and transfer them together, reducing freight costs by sharing them across orders.
This option adds an additional 1–3 week delay on top of the standard 1–3 week supplier lead time.
If you require your item sooner, please contact us before or after ordering to discuss specific lead times or faster freight options.
PPD Performance exhausts comprise of mandrel bent, stainless pipe work, delivering uncompromising flow, performance, and sound. Mandrel bending involves placing a mandrel inside the piping, before it is bent to shape. In comparison; cheaper press bending from other manufacturers squashes the tube as it is bent, reducing flow.
Tired of your mild steel exhaust systems rusting out after a year or less? Time to shop for a stainless steel system? There’s still some things you need to be aware of. Our competitors typically advertise their exhaust products as stainless steel. Most don't stipulate the differences between ferretic 409 grade stainless steel and austenitic 304 stainless steel.
Significant differences exist between the metals that make one better for performance exhaust applications than the other. Let us explain
The corrosion resistance of your 4x4 exhaust depends on the content of chromium and nickel found in the alloy. 409 grade stainless steel is used by many manufactures due to its medium strength, formability and very low cost. Typically, 409 grade stainless steel has a chromium content of between 10.50% - 11.75% and a nickel content of less 0.50%.
Why do we use 304 grade stainless steel piping for 4x4 performance exhausts? Because it is more resistant to rusting than ferretic based stainless steels such as 409. However, because of its low ferrous content, 304 can develop a golden colour when exposed to high heat over time. In fact, the ferrous metal content is so low that magnets won’t stick to it, making the identification of 409 and 304 grade stainless steel very easy.
Put simply, 304 grade stainless is the best value material used in the 4x4 exhaust game when strength, corrosion resistance and performance are at the top of your list of priorities.
Type 304 steel is engineered with chromium and nickel content and proves to be resistant to oxidation, corrosion, and durability.
Together with a polished finish - it is a great choice for your 4x4 offering excellent corrosion resistance from exhaust emissions, moisture and beach exposure.
All PPD Performance exhausts are designed to follow the same orientation and layout as the factory exhaust, making for easy bolt on installations. Our systems utilise the standard hanger locations, which means you don't have to use anything other than the factory rubbers.
