Crossmembers & K-Members for Mustang, Camaro, C10 & G-Body

What Crossmembers Cover

Structural and Driveline Support

Crossmembers support major vehicle systems across the chassis. The current selection includes transmission crossmembers, tubular K-members, engine mount kits and torque arm relocation hardware for specific Mustang, GM, Chevrolet and Jeep applications.

Transmission Crossmembers

Driveline Positioning

A transmission crossmember supports the transmission mount and helps maintain driveline position. Match the chassis, transmission, engine combination and mount style because a small change in drivetrain configuration can alter fitment.

Tubular K-Members

Front Suspension and Engine Mounting

A tubular K-member replaces the front structural member on certain Mustang and GM applications. It can change engine mount provisions and suspension packaging, so choose a kit designed for the vehicle and intended engine combination.

Engine Swap Mounts

Match Chassis and Engine

Engine mount kits in this collection support specified C10 and Mustang combinations. Verify the chassis year range, engine family, transmission and the required crossmember or mount hardware before starting an engine swap.

Installation Planning

Driveline Angles and Clearance

Crossmember installation can affect driveshaft clearance, exhaust routing, steering components and driveline angles. Support the vehicle safely, follow manufacturer torque values and inspect clearances at normal ride height.

How to Choose the Correct Crossmember

• Confirm the exact chassis year range and body platform
• Match the crossmember to the engine and transmission combination
• Verify whether engine mounts are included or sold separately
• Check transmission mount style and mounting-hole location
• Confirm compatibility with headers, exhaust and driveshaft routing

• Follow manufacturer torque values and installation instructions

Common Questions

What does a transmission crossmember do?

It supports the transmission mount and helps keep the drivetrain positioned correctly in the chassis.

Is a K-member the same as a transmission crossmember?

No. A K-member is a front structural and suspension component while a transmission crossmember supports the drivetrain farther back in the vehicle.

Will a Mustang K-member fit every Mustang?

No. Mustang K-members are specific to chassis generation, engine combination and suspension configuration.

Do engine mounts come with every crossmember?

No. Some listings include mounts while others require them separately. Read the specific product details before ordering.

Can I use a crossmember with any transmission?

No. Transmission case, mount location, tailhousing and drivetrain geometry affect compatibility.

Why do driveline angles matter?

Incorrect driveline angles can contribute to vibration and accelerated component wear. Confirm angles after installation at normal ride height.

Can I install a crossmember during an engine swap?

Yes when the crossmember and mounts are designed for the exact chassis and engine combination. Plan the engine, transmission and mount system together.

Are tubular K-members streetable?

Many are used on street cars, but selection and installation must match the vehicle, engine and suspension plan.

Which GM applications are in this collection?

Current listings include selected G-Body, F-Body and Chevrolet C10 applications. Verify the exact year range and drivetrain.

What should I verify before ordering?

Verify chassis, model year, engine, transmission, mount style, suspension configuration and clearance requirements.
