The kit includes two front motor mounts and one transmission mount made of alloy steel and a resilient rubber compound. It’s manufactured to match factory fit and mounting points for a fast swap while resisting weather, oil exposure and temperature extremes.

Which vehicles and drivetrains does this mount set fit?

This kit is built for late-model GM full-size trucks and SUVs with 4WD and V8 engines. Before ordering, confirm your vehicle’s model year, engine size and drivetrain configuration in your garage or owner’s manual to ensure compatibility.

How does the Mardarth kit match OE parts and mounting points?

This replacement kit is manufactured to align with many original equipment numbers so it installs with existing bolts and brackets. The dimensions, bushing positions and threaded holes are designed to mirror factory parts for a straightforward replacement with minimal adjustments.

• Direct replacements for OE references including 84175582, 84175583 and A2638
• Also cross-references commonly used numbers such as 3275, EM-4173, 20917337 and more
• Engineered to fit original mounting locations for simplified installation
• Includes the three specific pieces needed: front left, front right and transmission mount

What performance and durability features should you expect?

Materials and design focus on absorbing driveline shocks and resisting environmental wear so mounts last longer under load. The alloy steel body provides structural strength while the formulated rubber minimizes vibration without becoming brittle or deforming under heat or cold.

• Alloy steel housings for structural integrity and precise fit
• Advanced rubber compound resists cracking, oil contamination and temperature extremes
• Vibration-dampening design reduces cabin noise and protects engine components
• Tested for cold and hot conditions to maintain shape and performance

Should I install these mounts myself or seek professional help?

Experienced DIYers with the right tools can replace mounts, but professional installation is recommended for most owners. Proper torque, alignment and handling are important to avoid drivetrain stress or misalignment after fitting.

• Mechanics benefit from quicker swap times and reduced vehicle downtime
• Fleet or performance upgrades pair well with this kit for reliable service life
• If you lack specialty tools or mount-removal experience, use a certified auto shop
• Follow factory torque specs and safety precautions during installation
