Quick Hit: Silver Sport Transmissions Offers Tremec TR-4050 For 4x4s

Silver Sport Transmissions is celebrating the off-road way of life with a surprise announcement. The Rockford, Tennessee-based company is now offering Tremec TR-4050 transmissions for a wide variety of engines, and is sure to become a new best friend to any off-roader that loves a rock-solid manual transmission.

The first gear starts at a 6.16:1 ratio, making it a low-range beast for rock crawling. The reverse gear is similarly low-range, at 6.03:1. And this gearbox still has the goods to provide a good time on asphalt – at 5th gear, the ratio is .76:1 overdrive, making sure your rig doesn’t feel super-sluggish when all you want is high speed.

SST also offers an optional short-throw shifter called the STX, which borrows from the street/track/autocross discipline to provide a shorter throw and tighter feel. The shifter travels 20-percent less space from gear to gear, and can stand up to abuse thanks to an all-metal design. It makes for a great combination with the 4050’s multiple shift rails and internals offer terrific shift feel and performance. What’s more, the TR-4050 is fully synchronized, making shifting smooth between gears.

Right now, the TR-4050 can be ordered to fit a multitude of engines. These include the Cummins 4BTs and 6BTs, Coyote 5.0L V8s, Windsor small-block V8s, small-block and big-block Chevy V8s, LS V8s, and Mopar and Gen III Hemi V8s. To find out more, go ahead and check out SST’s website and Facebook page.

This 2002 Wrangler TJ is currently running the TR-4050 transmission and was seen at Easter Jeep Safari.
