Customer Reviews
Let customers speak for us
from 150 reviewsParts came sooner than expected and everything looks great. Now I can start gathering the rest of the parts I need.
More businesses should operate like SG! Very friendly folks and timely in shipping as well. Everything is as good as the pictures online too!
The help I got along was very helpful. Everyone I talked to there was nice
good quality
This site has my 5 star rating it’s great that there’s a company out there making parts for so many applications would order again in the future for any other projects Tks
Way better than I expected. Called before ordering, the representative was actually interested in what i was wanting to do. Did not just hurry up and get me off the phone, he took his time to talk to me. When I received the part there was a little extra in the box that I needed. I am extremely happy!! Will highly recommend Speedgem.
Good product, still to fit to motor and transmission. Have placed on motor, good fit, also on Transmission fits the only thing is the starter motor is on the opposite side to the 4L60e. But should not need much adjustment of bell housing to make it work.
All is good. Great communications. Kortney is was in constant contact with me. I was sent the wrong flex plate. They resent to me the right one. Thank you!!
These kits are fantastic. I bought a complete kit about 8 years ago and my starter went out, so I just needed a new one. No issues with the quality from Speed Gem. Customer service is great.
Great service great product
Can't wait to install everything. Product looks assume. Just the starter has a bit of damage on it but should be good.
I deal with hundreds of manufacturers and suppliers. Speed Gems and porter muffler are top notch.
I 100% recommend these guys' work, it's excellent.
GREAT QUALITY AND FAST SHIPPING - HIGHLY RECOMMEND!
I’ll message them with exactly what I had and they was able to let me know exactly what I needed within 30 minutes. I would definitely use this company again for any conversion. I do this time. It’s a T5 from a cobra R hooked up to a 383 stroker next time it’s gonna be the T5 to LS 6.0 for me.
