Silver Sport Transmissions Has Tremec’s TR-4050 For JK Jeeps

Tremec’s TR-4050 is well on its way to becoming the ultimate aftermarket off-road manual transmission as it continues to supplant its high-priced predecessors like the NV4500 and NSG370. Silver Sport Transmissions (SST) is where you can find one, but certainly not as some lonely, standalone stick shift.

Rather, SST puts together turnkey kits that can add some attitude to almost any trail rig. The latest package was professionally curated for 2012-2018 Jeep Wrangler JK models with 3.6L engines. Top to bottom, the Tremec TR-4050 is able to enhance versatility with lower first and reverse gears for crawling, a deep fifth, and full synchronization for smooth shifting.

A 24% overdrive ratio keeps fuel mileage manageable on the highway; everything in between is thoughtfully spaced for sensible gear changes that make kicking the clutch fun. Overall beefiness is not to be overlooked either as the TR-4050 touts a 600 lb-ft capacity that’s far and above any factory Jeep offering.

Kits include the transmission, pilot bearing, handle, hardware, knob, mount, and more. Additionally, unlike many rebuilt or remanufactured gearboxes, the TR-4050 comes with a full 12-month factory warranty. Without a doubt, it’s a brand-new transmission that can take a late-model Jeep from mild to mauler in the span of a weekend.

The best way to get on the path to performance is via SST’s Quick Quote form. From there, they can put together a perfect package that features all the fixin’s for a stress-free installation.
