YHB Engine Mount Adapter Kit for S10/Sonoma — Urethane Frame Mounts & 1/4" Steel Plates

YHB's Full Engine Mount Adapter Plates Urethane Swap Kit provides the brackets, hardware, and urethane frame mounts needed to install a 2.8L or GM LS-series engine into compatible S10/Jimmy/Sonoma platforms.

This kit packages heavy-gauge, laser-cut adapter plates, urethane frame mounts, and a full set of bolts and fasteners to support engine swaps on many Chevrolet and GMC compact trucks and SUVs from the 1980s through the early 2000s. Designed for durability and alignment, the components let you adapt a donor motor such as Chevrolet’s 2.8L or a range of LS engines (4.8L–6.2L families) into vehicles originally equipped with smaller engines. All metal parts are formed from high-quality steel and the frame mounts use stiff urethane bushings to reduce movement compared with stock rubber mounts.

Which vehicles will this mount kit fit?

The YHB kit targets a family of Chevy and GMC small trucks and SUVs sold between the early 1980s and mid-2000s. Fitment covers many two-wheel-drive models that accept the stock 2.8L footprint and common LS-swap orientations. Always verify year and drivetrain before ordering.

• Compatible models include Chevrolet S10, S10 Blazer, Chevrolet Blazer, GMC S15, GMC S15 Jimmy, GMC Jimmy and GMC Sonoma.
• Model years generally span 1982–2005 depending on specific sub-models; check the product listing for exact years.
• Allows LS-series swaps: LS1, LS2, LS3, LS6, LQ4, LQ9 and other common LS engines.

How is this kit built to handle engine swap stresses?

The adapter plates are 1/4" laser-cut steel with a multi-position design that gives you sturdier mounting points and more flexible engine placement options. Urethane frame mounts resist compression and deterioration better than factory rubber, so the assembly keeps the motor more secure under load. All included fasteners are sized to match the plates and mounts for a complete install solution.

• 1/4" laser-cut steel adapter plates for strength and repeatable holes.
• Two urethane frame mounts engineered to reduce deflection and last longer than rubber.
• Complete hardware kit: flange head bolts, motor mount bolts, washers and hex nuts included.

What comes in the box and what tools or parts will I still need?

The package supplies the adapter plates, two urethane frame mounts, and a comprehensive set of mounting hardware to bolt the assembly into place. It does not include an installation manual, specialty tools, or wiring components—those will be required depending on the swap complexity. Expect to provide standard shop tools and verify torque specs for your specific engine and vehicle.

• Included: (x2) 1/4" laser-cut plates, (x2) urethane frame mounts, (x8) flange head engine mount bolts, motor mount bolts, washers and hex nuts.
• Not included: step-by-step instructions, engine cradle modifications, or wiring/adaptors for electronics.
• Recommended extra items: torque wrench, shop manual for torque specs, and basic hand tools.

Will this kit work for modern LS engines in an S10 or Sonoma?

Yes—this YHB adapter kit is designed to accept many common LS family engines when performing an S10/Sonoma/Jimmy swap. It provides the correct mounting geometry for popular LS engines, but additional components like motor mounts for the engine block, driveshaft modifications, and clearance checks may still be needed.

• Supports LS-based engines including 4.8L, 5.3L, 6.0L and 6.2L variants where engine/transmission clearances permit.
• May require additional brackets or engine-specific mounts for some LS blocks/transmissions.
• Verify hood, steering and exhaust clearances before final installation.

Who is this for: The YHB Full Engine Mount Adapter Plates Urethane Swap Kit is aimed at experienced DIYers, professional shops, and performance builders undertaking engine swaps into classic S10/Jimmy/Sonoma platforms. If you’re converting a vehicle from the factory 2.8L footprint to a small-block Chevy or modern LS-series engine and need robust, reusable mounting solutions and matching hardware, this kit covers the core bracket and mount needs. It’s not a plug-and-play electrical or driveline solution; plan for additional parts and mechanical labor to complete the swap.
