MOSTPLUS front complete strut assemblies for 2007-2013 Silverado/Sierra 1500 — Set of 2, preassembled coils

MOSTPLUS front complete strut assemblies 189105/139105 are a direct-fit replacement set of two front struts engineered to restore handling and ride quality for 2007–2013 Chevy Silverado and GMC Sierra 1500 trucks.

If your Silverado or Sierra is showing symptoms like a bouncy front end, uneven tire wear, or steering wander, worn front struts are often the cause. These MOSTPLUS assemblies come pre-assembled with coil springs, mounts and hardware so you can swap them in without sourcing separate components. They are manufactured to match OE mounting points and service dimensions for a straightforward installation that gets your truck back on the road with predictable steering and suspension response.

How do these assemblies improve ride control on rough roads?

Replacing old, fatigued struts with complete assemblies helps re-establish original damping and spring support. That reduces excessive nose dive, minimizes rebound bounce, and keeps the front tires tracking consistently.

• Includes strut cartridges matched to original damping rates for the model years listed
• Factory-equivalent coil springs restore correct ride height and preload
• Integrated mounts improve alignment stability and reduce unwanted movement

Will these parts fit my 2007–2013 Chevy Silverado or GMC Sierra 1500?

These MOSTPLUS assemblies are made specifically for 2007–2013 Silverado and Sierra 1500 trucks, designed to align with the OEM mounting points and spring seat locations. Always verify your truck's model year and front suspension configuration before purchase.

• Part numbers cross-reference: 1336333, ST8583, 9214-0155, 139105, 810340, DG46007
• Sold as a set of two front complete strut assemblies (left and right)
• Exact-fit design recommended for the specified model years only

How difficult is installation and what comes in the box?

These assemblies arrive fully assembled—strut, coil spring, top mount and associated hardware—so they eliminate spring compression and component assembly at installation. Installation requires common suspension tools and a torque wrench; professional installation is recommended if you lack suspension experience.

• Included: two complete front strut assemblies ready to install
• Installation note: recheck alignment after replacement to prevent uneven tire wear
• Guaranteed exact fitment reduces modification or fabrication needs

What should I expect for durability and maintenance?

These MOSTPLUS assemblies are built to provide reliable service comparable to OE replacements when installed and aligned correctly. They help restore predictable handling and should be inspected during routine service intervals for leaks, mounting wear, or spring damage.

• Durable construction intended for regular driving conditions and light truck duty
• Inspect boots, mounts and hardware periodically for wear or corrosion
• Replace in pairs for even handling and consistent performance

Who is this for: This set is aimed at Silverado and Sierra 1500 owners (2007–2013) seeking a full front suspension refresh without hunting for separate springs or mounts. It suits DIYers comfortable with suspension work and professional shops that want a reliable, pre-assembled replacement to shorten labor time. Before ordering, confirm your truck’s model year and front suspension configuration to ensure compatibility.
