There are case histories of racers with over 600 runs on the units with no gear breakage , which prompted issuing the industry-exclusive warranty . Available for both solid-mount and 4-link applications , the housings are available in a variety of widths , with its modular design allowing it to be adapted to multiple vehicles . Link centers can be as narrow as 18 inches . Nine popular gear ratios are offered from 2.91 to 5.83 and custom ratios are an available option . they are designed to perform at higher operating angles than conventional U-joints , which can bind in cars with 4-link suspensions . It is also less prone to vibration . The CV driveshaft assembly is designed to work in conjunction with a “ shorty ” Powerglide transmission ( with 27- or 32-spline output shaft ) and features a CNC-machined billet aluminum tail housing , special CV joints that have been micro-polished to reduce friction and improve surface strength . The shaft is manufactured of high-strength 300M steel and a pinion yoke is also included .

McLEOD RACING
714-630-2764 www . McLeodRacing . com
McLeod Racing , a premier distributor of TREMEC , welcomes the new Magnum- F 6-Speed transmission . The new 6-Speed is designed to replace the T-56 transmissions in 1998-2002 GM F-bodies . The Magnum-F fills a longstanding void in the overall Magnum line with regard to shifter locations ; addressing not only LS1-powered ’ 98-02 F-bodies , but several other applications that utilize a similar shifter position . Where the original Magnum shifter locations may prove too far forward and the extended length Magnum XL ’ s too far back , the Magnum-F ’ s in-between position often proves to be just right . The Magnum-F leverages TREM- EC ’ s pervasive TR-6060 / Magnum architecture in order to provide fourth-gen enthusiasts significantly improved performance and relief from a shrinking pool of T-56 replacement parts . It increased face width on all gears , a robust combination of double and triple cone synchronizers , enhanced webbing in the main case , provisions for a cooler circuit and upgraded the shifter to an isolator type unit .
