G body cross member

Fantastic customer service, fantastic part and quality, they went above and beyond for me. Highly recommended.

Thanks. We're glad we could assist you. We appreciate the review and your business.

Great product

Thank You! We're glad you were pleased with your purchase.

Won’t hold for 450 horse

Didn’t hold up to 450 horse Cummins says 600 my foot

Thank you for taking the time to share your feedback with us. We’re sorry to hear that you’re not satisfied with the torque converter's performance. Given that it was purchased four years ago, it will be difficult to pinpoint the cause. However, we’d like to understand more about your issue. Someone from our Customer Service Crew will reach out to you.

We are adding an update because this information may help other customers who read this review: Paraphrasing your response 'I just got the truck together and running, just using the 450 horse package from power driven diesel. Ran for a month. Lockup quit locking up. Clutch is burned.'

We checked with our converter shop about the problem you described. They asked if you had checked your lockup solenoid. They stated that the lockup solenoid is known to fail, and when it does, it will burn up the clutch. They also noted that sometimes a scan tool will show the lockup solenoid to be activated by signal, but it is not actually engaged. Please check for this and let us know if there is anything else we can do to help.

79 t/a cross member

Haven’t installed it yet but it’s a nice looking part

We're glad to hear that you're happy with the transmission mount. We hope it will meet your expectations once installed. If you ever need any assistance, please don't hesitate to reach out to us. Thank you for choosing G Force!

Needs to get done a different way

The crossmember is not done right transmission sits to low really bad driveshaft angle needs to many spacer to compensate

Thank you for your feedback on our G-Body Crossmember. Because every installation is unique, we have taken this discussion offline and will try to troubleshoot your issue. We apologize for any inconvenience you may have experienced with the installation.

Very happy

Absolute perfect fit in 79 Trans am with Pontiac 400 and 200r4 trans. There are cheaper options out there, but these are good quality and should clear exhaust no problem. Will find out once exhaust gets installed. Fast shipping but could use more packing in the box.

Thank you for leaving a review! We're so glad to hear that our crossmember was a perfect fit for your 79 Trans Am. We work hard to offer high-quality products. We'll definitely take note of your feedback on the packaging for future shipments. Good luck with the rest of your install!

Transmission spacer

G Force did a wonderful job of going above and beyond to make sure I got my engine mount quickly, the part worked great and fixed my engine and transmission angle to match my pinion angle

Thank you. We're pleased to hear the part arrived when you needed it and it worked as expected. We appreciate the review.

Worked great save me a lot of time

Thanks for taking the time to share your review. We appreciate it.

Crossmember

Surprisingly, the crossmember fit perfectly. I put a 6L80E into a 1966 convertible GTO behind a Pontiac 400 with headers and 3" exhaust. Everything had to be customized but this fit right out of the box. Excellent quality product as well. Very impressed!

Thanks for letting us know. It's always great to hear that one of our Crossmembers fit as expected with no cutting or welding. We appreciate the 5 star review!

Helpful piece for set up

Would have given 5 stars but instruction sheet would have been welcomed. Very easy to assemble but had to check phone for video and pictures.

Thank you for the 4 star review. There should have been a card with a QR Code and URL that led you to the assembly video included with your purchase. If that was missing it was an oversite by our shipping department. We recently switched to this method of providing assembly instructions and installation tips. We've found that some of this information. like the Swap Block assembly, is better conveyed using video. We hope you found the Swap Block useful to your project and we apologize for any inconvenience.

Took 2 days to get a call back

You should have a person answer your phone a lot of us are older and not good with on line

Hello, Rob
We appreciate your purchase and are sorry we did not get back to you as quickly as you expected. Our team is generally very prompt at responding. We are a small business with an exceptionally knowledgeable customer service team but there are occasional glitches. Were your questions answered to your satisfaction? Please let us know if there is anything else we can do to assist you.

Stiff!

I installed these on my ultra low mileage survivor because there was absolutely no way I was taking a welder to the pristine underside of my car. These bolted right up and provide a ridiculous amount of rigidity to the sloppy fox body. Make sure your springs/shocks are in good shape otherwise you’ll be bouncing all over the place; yes these subframe connectors provide that much rigidity.

A couple of things not mentioned in the instructions. 1) you might need to loosen/remove the passenger side downpipe in order to get the nut plate into position 2) if your torque boxes are in factory condition(mine were) you may need to SLIGHTLY massage them in order to get the connectors to sit flush and line up with the bolt holes. Took me about 5 minutes with a block of wood and a hammer.

All that being said, don’t let anyone tell you that weld in subframe connectors are the only way to go. These things are the real deal!

Thanks for the great review and helpful tips. We appreciate your insights.

Heavy duty crossmemeber!!!

Worked great on my 1972 Chevelle

Excellent! Thanks for letting us know and for the 5 stars.

Ordered and installed, the converter only lasted 18 hours before shelling out

Thank you for reaching out to us. According to our records, this torque convertor was ordered in October 2022. Due to the length of time between placing this order and contacting us regarding your experience with the part, we will need to speak with you directly. One of our Customer Service Crew will reach out to you shortly.

Great product

Arrived quick

Great to hear! Thanks for the reveiw.

Mount and crossmember

Everything bolted right in. Worked awesome

Excellent! Very happy to hear it. Thanks for the review.

Fantastic quality. Unmatched!

There is a weird spot in the frame I had to contend with to place the 4L80e in a manner where I could use the factory shifter, otherwise, perfect! Super high quality piece. Will serve to stiffen the chassis a bit as well built as it is I imagine.

Glad it worked out, Andrew! Thanks for the 5 stars and positive review. We appreciate your business.
