Ford RacingAlthough known for its wide array of performance parts for Ford vehicles, Ford Racing also carries many of the best factory pieces, to allow for updates and upgrades of earlier models. One perfect example of this is Ford Racing's Z-spec T5 gearbox (M-7003-Z), presented as a brand-new assembly ready to bolt in. The Z-spec trans was originally developed for the '93 Mustang Cobra to handle the additional output of the Cobra-spec 5.0 engine. Internal upgrades and a change to different gearsets (including a 2.95:1 First gear in place of the standard World Class 3.35:1) raised the torque rating of the Z-spec box to 330 lb-ft, up from the standard World Class T5's 300-lb-ft rating. Similarly, Ford Racing also offers the Tremec 3550 (M-7003-R58) as an upgrade, using the parts put into production on the '95 Mustang Cobra R, where the beefy trans was called on to harness the additional torque of the R's GT-40-equipped 351W. Ford Racing also carries bellhousings, clutch kits, flywheels, driveshafts, and other related parts to complement your new trans. Plus, Ford Racing has rebuild kits for the T5 along with service replacement parts to convert your standard World Class T5 to Z-spec. Ford Racing, Clinton Twp, MI, 586/468-1356, www.fordracing.com
