Type 1 Drivetrain
Front Engine and Transmission - Driveshaft - Rear Differential
​
The four different Types of drivetrains all use the identical suspension kits and cradles -
and are mainly used for clarification purposes between
Dobbertin Performance and the builder.
​Once this incredibly versatile Corvette IRS is installed with our Corvette Interface Kit, you might notice that there's a lot of space to design your drivetrain in one of four distinct Types.
The Type 1 Drivetrain Configuration is available in two designs:
​Type 1
(First Design)
Incorporating the 5th Generation Camaro 'Hammerhead' Aluminum Differential
Front Engine and Transmission - Driveshaft - Rear Differential
​

The center photo shows our Camaro differential mounting kit, which allows the installation of a 2010 – 2015 5th Generation Camaro differential directly onto the C5 Corvette rear cradle.
-
The right photo shows our Camaro differential mounting kit installed on the cradle.
-
The next row, with two photos, shows the Camaro Differential Mounted on the cradle.
​
We are not currently offering the complete Camaro Hammerhead mounting kit,
but we do sell the three 3" x 3" uprights for making your own kit for $175.00.
​The 5th-Generation Camaro aluminum 'Hammerhead' differential is readily available online and in salvage yards for around $800.00 and comes in two factory ratios, including 3.27, found in automatic cars,
and a 3.45 found behind the manual transmissions.
​
​Other aftermarket ratios are available such as a 3.91 ratio direct from GM as well as 4.10 ratio and up from aftermarket manufactures.
​
Our installation kits will also work with most 9" Ford/Camaro differential conversions as well as the Strange Engineering and Lingenfelter 5th Generation Camaro differentials.

(Second Design)
Front Engine & Transmission – Driveshaft – C5 Differential with Yoke Adapter
​
​
Since all C5 and C6 Corvettes were produced with a mid-mounted transmission bolted directly to the differential, a driveshaft adapter must be mounted to the front of the Corvette differential when eliminating the transmission, to allow the use of a conventional driveshaft.
​
Any time a full-width cradle is used in a Type 1 application, the builder should consider the use of the Driveshaft Yoke Adapter. Although a bit pricey, (around $2,400.00) Everything else can remain factory stock, including the axles, springs and anti-sway bar, which makes the installation less expensive and very simple.
