Insane Shafts High Performance Left Hand Rear CV Axle | 2008-2015 Mitsubishi Evo X GSR (IS-613-D) 1000HP

Firstly, Buy Insane Shafts 1000HP Rear Left CV Axle Evo X IS-613-D for 2008–2015 GSR models. The Insane Shafts High Performance Left Hand Rear CV Axle is built for serious power in the Mitsubishi Lancer Evolution X. Part number IS-613-D is the 1000 HP version designed for the rear left, or driver-side, position on 2008–2015 Mitsubishi Evo X GSR models.

As power increases, the rear drivetrain must handle greater loads. Big turbo setups, increased boost, hard launches, and high-grip tires can place significant stress on the factory axles. For high-power Evo X builds, upgrading the rear axles can be an important part of building a stronger drivetrain.

The IS-613-D is made from Chromoly steel and receives a proprietary annealing and heat-treatment process. It is then cryogenically treated for additional strength. Insane Shafts designed this 1000 HP axle for demanding street, drag, and track applications.

Insane Shafts 1000 HP Rear Left CV Axle

The Insane Shafts IS-613-D is the high-performance rear-left CV axle for the 2008–2015 Mitsubishi Evo X GSR. It is designed for the 4B11T engine, manual transmission, and AYC rear drivetrain.

This axle is the 1000 HP version of the standard IS-613. The standard IS-613 is rated for 500 HP, while the IS-613-D is designed for applications up to 1000 HP.

The axle is sold individually. It is specifically for the rear left driver-side position.

If you need the matching rear-right axle, the corresponding 1000 HP part is IS-614-D.

Why Upgrade the Rear CV Axle?

The rear axles transfer power from the differential to the rear wheels. On a high-powered Evo X, they can experience substantial loads during hard acceleration and launches.

A stronger axle can provide additional support for a performance drivetrain.

Firstly, the IS-613-D uses Chromoly steel for its axle construction.

Secondly, it receives annealing and heat treatment to improve its strength.

Thirdly, the 1000 HP version receives additional cryogenic treatment. This process is intended to provide further strength for high-horsepower applications.

Together, these features make the IS-613-D suitable for Evo X owners building well beyond stock power.

Built for 1000 HP Evo X Applications

The IS-613-D is designed for Evo X builds that require more axle capacity than the standard 500 HP version.

A 1000 HP-rated axle is particularly relevant for cars with large turbochargers, built 4B11T engines, upgraded fuel systems, aggressive boost levels, and drag-oriented setups.

Hard launches can create sudden shock loads through the drivetrain. High-grip tires can also increase the load transferred through the axles.

For this reason, the rear axles should be selected based on the vehicle’s power level and intended use.

The IS-613-D provides a dedicated high-power option for the rear-left side of the Evo X.

Chromoly Steel Construction

Insane Shafts uses Chromoly steel for its high-performance axles. The 1000 HP version receives the company’s proprietary annealing and heat-treatment process before additional cryogenic treatment.

This multi-stage treatment is intended to increase strength for demanding applications.

The result is an axle designed for Evo X owners who need more than a standard replacement component.

Whether the vehicle is used on the street, at the drag strip, or on a road course, the IS-613-D is built with high-power drivetrain demands in mind.

Cryogenic Treatment for the 1000 HP Version

One of the key differences between the standard and 1000 HP Insane Shafts axles is the additional cryogenic treatment.

The standard 500 HP axle receives the annealing and heat-treatment process. The 1000 HP version adds cryogenic treatment to the process for additional strength.

This makes the IS-613-D a more appropriate choice for extreme-power Evo X builds where the standard IS-613’s 500 HP rating is not sufficient.

Rear Left Driver-Side Fitment

The IS-613-D fits the rear left side of the 2008–2015 Mitsubishi Evo X GSR.

On a left-hand-drive vehicle, this is normally the driver side.

The matching rear-right 1000 HP axle is IS-614-D. Make sure you select the correct side when ordering.

The listed application includes:

• 2008–2015 Mitsubishi Lancer Evolution X
• GSR
• 4B11T
• Manual transmission
• AYC rear drivetrain
• Rear left / driver side
• 1000 HP application

Important: Current product listings specifically state that these Insane Shafts rear axles will not fit Evo X MR models. Verify your drivetrain configuration before ordering.

ABS Ring and Spindle Nut Included

The IS-613-D includes a removable ABS ring and a new spindle nut.

These features make the axle a practical replacement for a performance Evo X build.

Before installation, inspect the rear wheel bearing, hub, differential output, axle seal, and related hardware. Replacing a high-performance axle will not correct problems caused by worn supporting components.

The IS-613-D is designed for Evo X owners who are building serious power.

It can be considered for:

• 1000 HP Evo X builds
• Large turbo 4B11T engines
• Built engine applications
• Drag racing cars
• High-power street cars
