Description

Connect your 4BT Cummins directly to your Jeep stick transmission. This adapter fits 4.0L INLINE six transmissions only. Later V6 versions of the NSG370 will NOT work with this kit.

The advantage with this kit is the clutch pressure plate and hydraulics used are all stock Jeep components. This means they will actually work right and feel right. Other kits on the market need to accomplish this by mixing  pressure plates and slave cylinders resulting in poor or improper clutch disengagement.

NOTE: Be aware with using this kit you MUST test fit your bellhousing and you may need to grind minor reliefs for the starter pinion gear and/or the flywheel ring gear teeth. This kit fits several different transmissions over a large span of years. there are variations in the bellhousings in this span and how much grinding is required. Normally, minimal clearancing is required.

 

Kit includes:

Solid 6061 Aluminum bellhousing adapter

Forged and fully machined medium carbon steel flywheel

Ball pilot bearing and bolts

Requires 2008+ 6.4/6.7 Ford Powerstroke starter (not included)

    Awesome kit. Worked well. with the NSG370 i had to grind a small amount off various support ribs in the casting and a 3″ or so area around the starter cone casting in the transmission.

    Althought the flywheel bolts where not included I will still give this 5 stars. I ordered some ARP bolts instead.

    Flywheel even has the notches for the crankshaft sensor to work so that the ECM will allow the instrument panel to work with the 4BT once you adapt the other sensors. on years after 1999 i believe you also have to trick the cam sensor, but mine is 98 so this is great.
