Hold a gallon of milk in front of you with your arm stretched out. After a while, it starts to get heavy right? Now make it 80lbs and about $1500. The 48RE Dodge diesel 4WD transmissions from 2003-2007 are known for repeatedly cracking the overdrive housing. The transfer case is mated to the overdrive housing but has absolutely nothing in place to support that 80lbs aside 6 bolts. SunCoast's Transfer Case Support solves this issue with a specially designed steel bracket that installs in place of the lower two bolts (longer bolts supplied) and includes the common GM universal mount.
With the constant twisting and flexing of the tail housing usually seen in 450hp+ builds or those who tow regularly, it is not uncommon to see constant leaks from the tail housing where it meets the transfer case. This constant torsional flexing and fatigue cause repeated fluid leaks and damaged housings. By using the factory skid plate, and the GM mount, you have additional support for casing, preventing those damages.
What's interesting though, is this kit fits as though Dodge intended a support to be there. The factory skid plate actually has existing holes drilled already. This kit includes a machined steel spacer/washer (fits below the skid plate) with a tapered groove to clear the OEM stamping.
Now, if you don't have the factory skid plate, all hope is not lost. This kit can be installed by installing the following parts below available from Chrysler (sold separately):
- Skid Plate 52022048AH
- Crossmember 52022046AE
- Bolts (8 required) 6507342AA
