G Force Z32 and Z33 Transmission Adapter Swap Kits For LS conversions

What is an LS Conversion?

An LS conversion involves the swapping and installation of engines into an existing vehicle. LS stands for any engine manufactured by GM. This is the primary V8 engine manufactured by GM and widely used in the Chevy Corvette beginning in 1997. It’s a popular choice for aftermarket engine conversions also known as LS Swaps.

Can I put any type of engine in any type of car?

You could potentially swap engines of different makes to almost any model of car. However, the cost may be a factor in that decision. To avoid wasting money on an LS conversion, be sure to talk to a reliable engineer before servicing the vehicle. Based on your budget and the performance you’re looking for, an experienced professional can help you determine which engine will work best.

What is the estimated cost for a custom engine swap?

Custom swapping an engine varies significantly in cost depending on the involved materials and cars as well as the amount of labor necessary for completing the swap. Prices can range from as low as $1,500 to higher than $12,000.

G Force Adjustable Transmission Mount Replacement

Adjustable Transmission Mount for LS Swap

Our Adjustable Transmission Mount offers an innovative simplicity for improved efficiency and stability. Because it allows for an offset of 1 to 2.5 inches, this product is ideal for LS conversion applications requiring the moving of your transmission from its stock location. The simple, bolt-in mount design also prevents swapping misalignment.

As a result, your transmission will accurately align with your drivetrain without issue. We have designed the adjustable transmission mounts with strong mounting hardware and polyurethane bushing. It fits most manual or automatic GM RWD transmissions. Additionally, the mount is adjustable before securing the slide bolt with an install height of 1.75 inches, so you can accurately place the assembly. NOTE: Check your current transmission mount's pattern dimensions to confirm it matches prior to purchasing a mount replacement.

Our Products

This list of components for LS swaps brings us to where our products fall in line with solving the complex problem that is an LS conversion. For traditional style LS conversions, we offer transmission crossmembers and some motor mounts for specific conversions. The adapter plates that we offer solve very specific problems for customers. IE, customers who want to convert a specific transmission and motor into any platform. Although these kits might allow customers to choose different transmission and motor combinations, it does not solve a customers desire to convert these specific motor and transmission combinations into specific platforms or cars. Pairing these adaptor plates with transmission crossmembers or motor mounts would allow them to be considered “LS conversion kits” as oppose to “LS Conversion components”

A transmission crossmember from G Force allows our customers to convert transmissions into specific applications, but solves no other concern. You can learn more about why our customers choose G Force and finding the right crossmember for your project.

G Force motor mounts allow customers to convert specific motors into specific applications or platforms but solves no other concern.

In addition, our transmission adaptor plates allow our customers to combine specific motor and transmissions but solve no other concern.
