GM LS engine swappers, this YHB Flexplate Adapter Kit is exactly what you need to mate your modern LS engine to older GM transmissions!

This complete kit makes your Gen III LS swap so much easier by adapting LS1, LS2, and LS6 engines (including 5.3L and 6.0L truck engines) to work with TH350, 700R4, 4L60, 200-4R, and Powerglide transmissions.

The kit works with both 10.75-inch and 11.066-inch bolt-pattern torque converters, giving you flexibility in your build.

You get everything needed in one package: the transmission adapter flexplate with 168-tooth steel ring gear, 6 Gen III LS flexplate bolts (M11 x 1.5 thread), an LS crank sleeve adapter, and a torque converter bolt kit.

The construction is top-quality cold-rolled premium steel with a gold iridited finish that prevents rust and looks professional.

The adapter flexplate works perfectly with your stock LS starter motor, and the crank sleeve adapter has precise dimensions (1.04-inch overall height, 1.47-inch inside diameter) for proper fitment.

This kit fits 1997-2007 GM LS1/LS6 engines and up to 2009 for LS2 models, plus various truck engines including L33, L59, LM4, LM7, LQ4, LQ9, and LR4.

Whether you're putting an LS engine in an older muscle car, truck, or any project vehicle, this adapter kit eliminates the guesswork and ensures everything mates up properly.

The quality is immediately apparent when you open the box - the machining is precise, the steel is substantial, and the gold finish looks durable.

Installation is straightforward if you're familiar with transmission work, and having all the necessary components in one kit saves you from hunting down individual parts.

It's one of those essential components that makes LS swaps so popular and achievable for home builders.

Your LS swap project will go so much smoother with this properly engineered adapter solution!
