So I've ran a little more than 4-5 3s packs through my BR and both rear axels separated at the yokes. The HD CVDs are out of stock everywhere. The parts to BUILD them are out of stock everywhere. I've been told the HR CVDs are poorly designed and I think that leaves me the GPM CVDs which have mixed reviews. The stock axels are not an option at $20 a run. Neither is waiting over a month on Horizons supply chain issues.

Who here is *actually* using the GPM CVDs? What is your driving style? Are you running stock power and punch settings? How long have they held up? Thanks!

PS. Admins. This hobby is full of 3 letter words, manufacturers, and acronyms we should be able to search. Ie. Pin, Hub, CVD, Nut, Hex, Cup, GPM, HOT, Etc. Do I have to use advanced search for this? Or is this something we can look into fixing? I got nothing of relevance on 'Big Rock GPM CVD'.

Have on rear of my BR have 2 packs on um. 3S
1 punch setting 30k diff in rear with 6s shocks all way around. Was going through stock shafts per pack, if they would last that long!! Front are still stock, waiting for delivery from GPM, mid to late October.

Nice! I'm happy with the GPM CVDs on the rear of my Big Rock and I run it on 4s and still have not had any problems with them after almost 3 months.
