PRODUCT NEWS:
Say Hello to the Bad Guy-- TREMEC's New Magnum XL is Here!
The most highly anticipated product release from
TREMEC since the launch of the original Magnum 6-speed nearly three years
ago, the Magnum XL for S197 Mustangs , has finally arrived! Those of you who
have been following the drawn out process of getting this transmission to
market, will undoubtedly join us in our excitement! For those of you not
familiar, allow us to introduce the new MAGNUM XL 6-SPEED...
Beginning with an all-new "extended length" rear extension housing, the
Magnum XL is intended for late model performance applications, cursed with
factory "semi-remote" shifters. By offering the owners of these vehicles a
rigid, "direct-shift" with the Magnum XL, gone are the days of clumsy,
rubbery-feeling gear changes. Like the rest of the Magnum line, the XL
offers crisp, low-effort shifts, and an industry leading 700 lb-ft. of
torque capacity!
Additionally, thanks to it's OE-derived & race-proven synchronizer
technology, the Magnum XL is equipped to deal with all but the highest
revving engines, with an rpm capacity nearing 8,000 rpm straight out of the
box!
It's big, its brutal, and yet oh-so sophisticated! As hardcore
performance enthusiasts ourselves, we have extremely high hopes for this new
transmission, and believe it is going to make a huge impact on the late
model performance scene! Initially available for 2005-up "S197" Mustangs,
the Magnum XL will eventually be available for most popular late-model
applications, and comes complete with an SFI-approved steel bellhousing,
swap-specific crossmember and mount, a truly awesome short-throw shifter,
and all the necessary hardware to bolt it in your car!
PLEASE NOTE: All Magnum XL conversions will require a 26-spline clutch and
1-piece driveshaft (sold separately). Additionally, supplies are limited due
to significant demand. For complete details and pricing information, see
your preferred TREMEC Distributor, Standard Transmission & Gear, Inc.
