YHB Full Engine Mount Adapter Plates Urethane Swap Kit for 1982–2005 S10/Blazer/Sonoma - Laser-Cut 1/4" Steel Plates & Urethane Fr

YHB Full Engine Mount Adapter Plates Urethane Swap Kit lets you install LS-family engines into 1982–2005 S10, Blazer, Jimmy and Sonoma trucks with a robust urethane frame mount and laser-cut steel adapter plates.

Designed for popular small-truck LS swaps, this kit replaces original rubber frame mounts and adapter hardware with heavy-gauge steel plates and urethane mounts to secure motors such as LS1, LS2, LS3, LQ4, LQ9 and others into 2WD S10/Blazer/Jimmy/Sonoma platforms originally equipped with the 2.8L Chevrolet engine. The package contains laser-cut adjustable plates, flange hardware and urethane frame mounts so you have the core parts needed to position and fasten the engine safely to the factory frame locations.

How does this kit help fit an LS engine into an S10 or Blazer?

The adapter plates provide multi-position mounting points so you can accurately align LS-series engines to the truck’s frame. Laser-cut 1/4" steel plates give consistent hole patterns and locations for repeatable installation, while the urethane frame mounts replace soft factory mounts for improved hold.

• 1/4" laser-cut steel adapter plates with multi-position holes
• Urethane frame mounts sized for 2.8L swap locations
• Flange head engine mount bolts and motor mount hardware included
• Compatible with LS1/LS2/LS3/LS6/LQ4/LQ9 and similar engines

What parts are supplied and what will I still need?

The kit ships with the two laser-cut adapter plates, two urethane frame mounts, and a set of bolts, washers and hex nuts to secure the mounts and engine brackets. It covers the core mounting hardware but does not include detailed instructions, engine mounts from donor motor, transmission crossmember or wiring—those are typically sourced or modified during a complete swap.

• Included: x2 adapter plates, x2 urethane frame mounts, x8 flange head bolts, x2 motor mount bolts, washers and nuts
• Not included: installation instructions, donor engine motor mounts, crossmember or wiring harness
• Requires basic fabrication or mock-up to finalize engine position

Will these mounts withstand street and track use?

The adapter plates are made from 1/4" laser-cut steel for high strength, and urethane frame mounts resist twisting and degradation better than stock rubber. While urethane is firmer and improves rigidity, expect added engine noise and firmer vibration transfer compared with original rubber mounts.

• Heavy-gauge steel resists flex under load
• Urethane mounts offer longer life and improved stability
• Firmer mounts increase perceived vibration compared to OEM rubber

Which vehicles and engines are compatible with this swap kit?

This kit targets 2WD Chevrolet S10, Chevrolet Blazer, GMC S15, GMC Jimmy and GMC Sonoma model years listed below and fits common LS-family V8 engines used in swaps. It was engineered with the original 2.8L engine truck mounting locations in mind.

Who is this for: This YHB kit is aimed at experienced DIYers, professional fabricators and swap enthusiasts who are performing an LS or larger V8 conversion into second-generation S-series trucks and related Blazer/Jimmy/Sonoma models. If you plan to reuse donor motor mounts, want stronger frame attachment points, and are prepared to handle mock-up alignment or additional fabrication (crossmember, driveline and wiring), this kit supplies the essential adapter plates and urethane frame mounts to move the project forward.
