Transmission Adapters

Seeking better performance and fuel efficiency is an ongoing journey for many jeepers, with a variety of upgrades and modifications that all contribute to this goal. Engine and transmission mods and replacements are commonly turned to as a solution for this project. Upgrading the transmission in your rig is rarely straightforward, though - the interface between engine and transmission must line up just right or it won't take at all. 4WheelParts.com provides transmission adapters for sale to make sure that replacement you've been eyeing installs just right under the hood, no matter what your year, make and model is.

The Perfect Fit

Factory-made transmissions often don't cut it for Jeep enthusiasts, especially when off-roading or dealing with heavy cargo. However, transmissions are designed for specific engines in mind - a particular bolt pattern, spacer thickness and, for auto transmissions, connection between the torque converter and crank shaft. A Jeep transfer case adapter kit from Advance Adapters makes managing this easier; it includes all the parts needed to install the adapter and make your engine ready for the new transmission. Our online catalog lets you filter based on your rig's specs, and our team of experts can guide you in how to best use a transfer case adapter.

DIY jeepers are familiar with the hefty budgets that come with their projects. Fortunately, your new Wrangler transfer case adapter doesn't have to break the bank - get it from 4WheelParts.com for a low price you can be sure of. Our price match guarantee means that, for any product you order, we match any competitor's lower price within up to 90 days of your purchase. Many items in stock also qualify for free shipping, and if it doesn't work out, you have several options to choose from for making a return or exchange.
