Description
A twin-tube design with a 40mm piston and a 20mm shaft provides excellent performance and is designed to give a more comfortable and improved ride.
Low-pressure Nitrogen Gas prevents cavitation of oil inside the shock when it heats up during use over rough roads, allowing the shocks to work more consistently.
The piston has a Teflon coating, allowing it to slide smoothly with less friction.
Highly polished Chrome shaft ensures long shaft life.
The shock absorber velocity sensing valve can accurately control the required damping force for different conditions.
High-quality seals are designed to protect against oil leaks and perform very well even in dusty and dirty conditions.
40mm Piston
Our Superior Nitro Gas Shocks feature a robust 40mm Teflon-coated piston, engineered for enhanced durability and smooth operation. These shocks also incorporate a sophisticated velocity sensing valve stack, designed to provide optimal damping performance by automatically adjusting to changing driving conditions, ensuring a superior ride quality and improved handling.
Shock Shaft
The 20mm steel shaft features a high-polish, chromium-plated finish, specifically engineered for long-lasting durability and resistance to corrosion. This ensures optimal performance and an extended lifespan even under demanding conditions.
Nitrogen Gas Charged
Nitrogen Gas (Nitro Gas) charged to minimize cavitation during the high-speed oscillations encountered in off-road conditions, ensuring consistent performance and stability.
Welded Pins & Eyes
Superior Engineering Nitro Gas shocks feature fully welded pin and eye ends, a design choice that surpasses the spot weld system used by some other shock manufacturers. This robust welding method significantly reduces the likelihood of shock failures.
Twin Tube Design
The twin-tube design allows for increased oil capacity without the need for remote reservoirs, effectively maintaining cooler operating temperatures during off-road use. This design ensures better performance and longevity of the shock absorbers under demanding conditions.
Rubber Shaft Boot
All Superior Nitro Gas shocks come equipped with silicon rubber protective boots. These boots safeguard the shocks from rocks and other debris that could potentially damage the shaft or seals, ensuring enhanced protection and longevity of the shocks.

WARNING: This shock absorber contains pressurised gas. Do not open, puncture, cut, heat, weld near or try to take the shock apart. Releasing the gas pressure the wrong way can cause serious injury. Servicing should only be done by a qualified shock technician with the correct equipment.
Regular servicing keeps your shocks damping the way they should and helps them last longer, especially after heavy touring, corrugations or long periods off-road. Superior Engineering offers shock servicing through our workshop. To find out what's involved and to book a service, visit our Shock Servicing page.
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.
