I'm in no way related to Tremec or Silver Sport Transmissions, but I stumbled across this on the social medias and felt it pertinent to share.

No idea on cost, but at the rate NV4500's are going, and the limited bellhousing arrangement and overall size limitation, this may be a lucrative alternative.

To launch our new 4WD TREMEC TR-4050 PerfectFit™ Kit for TJ platform Jeeps, we purchased a 2002 Jeep Wrangler. This Wrangler came with the legendary 4.0L I6 Power Tech Engine, a 5-Speed NV3550 manual transmission, a 3.07 rear axle ratio, and P215/75R15 RBL Wrangler AT tires. The previous owner did some common customizations to the Jeep, including adding 33x12.50 R15LT tires which took the Jeep from 28" to 33" tires.
Our PerfectFit Kit for the TJ platform comes with everything you need to convert to the TR-4050 5-Speed, from the pilot bearing to the driveshaft. You'll be very happy with this upgrade over your old NV3550, NV4500 or AX15.
You can tell from the initial driving video below, the new tire height greatly effected the gearing. We wanted to improve the driving experience for not only those who run these oversized tires, but also for people who would like a little more torque in their lowest gear and reverse when crawling or mudding.
No idea on cost, but at the rate NV4500's are going, and the limited bellhousing arrangement and overall size limitation, this may be a lucrative alternative.
