Yllshengyu Engine and Transmission Mount Kit for 3.8L V6 — 4-Piece OE-Style Replacement, Reduced Vibration

Yllshengyu's four-piece engine motor and transmission mount kit replaces factory mounts on many 3.8L V6 GM models to restore stable engine positioning and reduce vibration.

This complete mount set from Yllshengyu is designed as a direct-fit replacement for worn or damaged engine and transmission mounts found on a range of Chevrolet, Buick, Oldsmobile and Pontiac vehicles using the 3.8L V6 (and select 3.6L/5.3L) engines. Built to meet OE-style specifications, the kit brings back secure engine alignment and improved NVH (noise, vibration, harshness) management so drivability feels more controlled and refined after installation.

Which vehicles will these mounts fit?

The kit covers numerous GM models across late 1990s and 2000s model years that used the 3.8L V6 and a few compatible 3.6L/5.3L variants. Fitment is broad but specific to year, model and engine combination, so verifying your exact vehicle before purchase is essential.

• Chevrolet Impala (2000–2005) and Monte Carlo (1998–2005) with 3.8L V6.
• Buick Allure, LaCrosse (2005–2009) with 3.8L V6; LaCrosse 2005–2008 with 3.6L V6.
• Buick Regal (1997–2004) and Pontiac Grand Prix (1997–2008) 3.8L V6; Grand Prix 2005–2008 with 5.3L V8 where applicable.
• Oldsmobile Intrigue (1998–1999) with 3.8L V6.

What parts are included and which OE numbers do they replace?

This pack contains the four primary mounts commonly replaced during engine/transmission mount overhauls. Each piece is manufactured to directly replace original equipment for hassle-free swapping and correct engine positioning.

• 1x Front Left Torque Strut Mount and 1x Front Right Torque Strut Mount for engine torque control.
• 1x Front Left Motor Mount and 1x Front Right Motor Mount to secure the engine to the subframe.
• Replaces OE numbers such as 10271462, 10230877, 10230878, 10420009 and aftermarket equivalents A5309, A2866, EM2866, EM3088, 3088, 2866.

How do these mounts improve driving feel and longevity?

Worn mounts allow excess engine movement, increased vibration, and drivetrain stress; replacing them with a matched OE-style kit reduces movement and distributes torque forces correctly. The Yllshengyu set is produced from quality materials and evaluated under strict quality control to provide consistent damping performance.

• Reduces engine vibration transmitted into the cabin for quieter operation.
• Improves throttle response perception by stabilizing engine position under load.
• Helps prevent accelerated wear on related components like hoses and exhaust joints.

What should I check before ordering and during installation?

Confirming compatibility with your vehicle is the best first step; use seller fitment tools or reference your VIN and engine code. During installation, inspect surrounding mounting points, brackets, and hardware so the new mounts can perform without interference.

• Use Amazon Garage or your vehicle’s VIN to verify correct fitment before purchase.
• Inspect engine mounts, brackets, and subframe for damage; replace corroded bolts if needed.
• Torque mounting hardware to manufacturer specs and check for alignment after initial driving.

Who is this for? This Yllshengyu four-piece mount kit is tailored for DIYers, independent mechanics and fleet technicians maintaining late-1990s to 2000s GM cars equipped with the 3.8L V6 (and certain 3.6L/5.3L applications). It suits owners replacing aged, cracked, or oil-swollen mounts who want a direct OE-style swap that restores engine stability, reduces vibration, and helps protect adjacent components. If you’re unsure about fitment, contact support or confirm your model and engine details before ordering to ensure proper compatibility.
