sure, i have iam the owner! thanks for the inquiry.i have been in the auto biz since 1984. i have been a streetracer in brooklyn and the bronx for years .as well as at the track .thru my career i have developed a number of different ratio planetary gears for the 350 2004r and the 4oo.we custom designed transbrakesfor these transmissions as well.my approach to these products is not at all remotely close to the others making them truly unique.basic trans knowledge does not account for our customers going 7.40 at 198 mph with a 3500 lb car,7.60 at 194 mph at 3600 lbs .turbo buicks and big block powered malibus have gone low 9s with our 2.48 ratio 8 pinion 2004rs with our 4340 steelinput shaft and drum assemblies.i am truly dedicated to the trans biz and it aint for the money. in fact .thanks for welcoming me and hope you enjoy my teck .it is always direct and to the point .no b.s. ill have a banner soon so check out the site at ckperformance.com
