Business Name: High Torque Diesel LLC
Website: hightorquediesel.com

High Torque Diesel LLC sells diesel truck parts, accessories, and performance products that may be subject to federal, state, or local emissions requirements.

Emissions requirements can vary depending on factors including:

• Vehicle year
• Make and model
• Engine
• Engine configuration
• Product type
• Intended use
• Vehicle registration location
• Inspection requirements
• Where the vehicle is operated

Customers are responsible for determining whether a product is permitted for their specific vehicle, location, and intended use before purchase, installation, or operation.

Emissions-Control Equipment

High Torque Diesel LLC does not recommend removing, disabling, bypassing, defeating, or tampering with emissions-control equipment that is required by applicable law.

Depending on the vehicle, emissions-related systems or components may include:

• Diesel particulate filters
• Exhaust gas recirculation systems
• Selective catalytic reduction systems
• Diesel exhaust fluid systems
• Catalytic converters
• Exhaust sensors
• Engine and emissions sensors
• Electronic engine controls
• Manufacturer-installed aftertreatment equipment
• Other emissions-related components

Customers should follow applicable legal requirements and manufacturer instructions when servicing or modifying emissions-related systems.

Product Listings

The presence of a product on hightorquediesel.com does not automatically mean that the product:

• Is approved for every vehicle
• Is legal for use in every state or jurisdiction
• Is approved for street use
• Meets every local inspection requirement
• Is compatible with every engine configuration
• Is permitted for every intended use

Customers should review all available manufacturer information before purchasing.

This may include:

• Product descriptions
• Emissions notices
• Manufacturer disclaimers
• Vehicle applications
• Installation instructions
• Restrictions
• Certification information
• Intended-use statements

Manufacturer requirements should be reviewed carefully before installation.

Fitment Does Not Equal Legal Compliance

A product may physically fit a vehicle without being permitted for every use or location.

Vehicle fitment and emissions compliance are separate considerations.

A product appearing in a vehicle search, category, filter, or fitment list on our website does not automatically establish that the product is permitted for:

• Street use
• Registration
• Inspection
• Sale
• Installation
• Operation

Customers should separately verify both fitment and applicable emissions requirements.

Please review our Fitment & Installation Policy for additional fitment information.

Street Use

Products intended for normal street use should be used in accordance with the manufacturer’s instructions and any applicable emissions requirements.

Customers are responsible for verifying that a product is permitted for use on public roads in the location where the vehicle is registered or operated.

Competition, Racing, and Off-Highway Products

Certain automotive products may be described by a manufacturer as intended only for:

• Racing
• Competition
• Off-highway use
• Closed-course use
• Other limited applications

Products with these restrictions should only be purchased, installed, and used in accordance with the manufacturer’s stated requirements and applicable law.

A product described as being for racing, competition, or off-highway use should not be assumed to be legal for street use.

Manufacturer Emissions Information

Manufacturers may provide emissions-related information such as:

• Product-use restrictions
• Certification information
• Application limitations
• State-specific restrictions
• Installation requirements
• Competition-use notices
• Other compliance information

Customers should review the most current manufacturer information available for the specific product.

High Torque Diesel LLC may provide links or references to manufacturer information when available, but customers should confirm current requirements before purchase or installation.

State and Local Requirements

Vehicle emissions requirements can differ between states and local jurisdictions.

Some locations may have additional requirements relating to:

• Vehicle inspections
• Product certification
• Registration
• Emissions testing
• Aftermarket components
• Street-use eligibility

Customers are responsible for determining which requirements apply where the vehicle is:

• Registered
• Inspected
• Sold
• Installed
• Operated

When necessary, customers should review current information from the applicable government agency or product manufacturer.

California and Other Restricted Jurisdictions

Certain products may have additional restrictions in California or other jurisdictions with specific emissions requirements.

Customers should review manufacturer documentation and current local requirements before ordering products for use in a restricted jurisdiction.

The ability to purchase a product through our website does not by itself mean the product is permitted for use in that location.

Installation Does Not Determine Compliance

Professional installation does not automatically establish that a product is legal or compliant for a particular vehicle or location.

The customer remains responsible for confirming that:

• The product is appropriate for the vehicle
• The intended use is permitted
• Applicable emissions requirements are satisfied
• Manufacturer restrictions are followed

A professional installer may also have its own requirements regarding what products it is willing or legally permitted to install.

Modified Vehicles

Existing vehicle modifications may affect emissions compliance, fitment, operation, or manufacturer warranty coverage.

Examples may include:

• Custom tuning
• Intake modifications
• Turbocharger upgrades
• Fuel-system modifications
• Exhaust modifications
• Engine swaps
• Transmission changes
• Other aftermarket components

Customers with modified vehicles should review the effect of those modifications before purchasing additional products.

Product Changes

Manufacturers may change:

• Product designs
• Part numbers
• Certifications
• Vehicle applications
• Intended-use statements
• Installation requirements
• Emissions classifications

These changes may occur without notice.

High Torque Diesel LLC may update product information when new information becomes available, but customers should verify current manufacturer information when emissions compliance is important.

Changes in Laws and Regulations

Emissions laws, regulations, enforcement practices, inspection requirements, and product certifications may change over time.

Information that applied when a product was originally manufactured or listed may later be revised.

Customers should review current requirements before purchasing, installing, or operating emissions-related products.

Customer Responsibility

Before purchasing an emissions-related or performance product, customers should consider:

• Their specific vehicle
• Vehicle modifications
• Product part number
• Manufacturer requirements
• Intended use
• Registration location
• Inspection requirements
• Applicable emissions rules

High Torque Diesel LLC does not guarantee that a product is permitted for every vehicle, application, or jurisdiction.

Returns

Emissions restrictions do not automatically make an installed or used product eligible for return.

Customers should verify applicable requirements before installation.

Products that have been installed, programmed, modified, used, or otherwise altered may be subject to the restrictions in our Returns & Refunds Policy.

Warranty

Emissions-related modifications may affect manufacturer warranty coverage depending on the vehicle, product, installation, and applicable manufacturer terms.

Customers should review our Warranty Information page and the applicable manufacturer warranty before purchase or installation.
