The Texas Speed Hemi 3-Bolt Conversion Cam Gear replaces the factory VVT phaser on a Gen III Hemi with a fixed three-bolt cam gear, the mounting style Texas Speed has used on its LS camshafts for years. It is the matching drive gear for the Texas Speed line of 3-bolt Hemi camshafts and is required to run one of those cams.
Deleting the phaser and moving to three bolts gives the camshaft a stronger mounting interface and, according to Texas Speed, reduces the risk of a sheared dowel pin that can result from torque problems with the single-bolt factory design. Texas Speed also notes the conversion is simpler to install than a traditional VVT lockout. The gear is for Gen III Hemi engines using Texas Speed 3-bolt camshafts and is not used with single-bolt VVT-style cams.

FAQ
What is the Texas Speed Hemi 3-bolt conversion cam gear for?
It replaces the factory VVT cam phaser on a Gen III Hemi with a fixed three-bolt gear so a Texas Speed 3-bolt Hemi camshaft can be installed. It is the required drive gear for that camshaft line.
Can I use this gear with a standard single-bolt Hemi camshaft?
No. The gear is designed for Texas Speed 3-bolt Hemi camshafts, which have a three-bolt nose instead of the factory single-bolt pattern. A factory-style or single-bolt aftermarket cam uses the VVT phaser or a phaser lockout instead.
Which Hemi engines does the 3-bolt conversion gear fit?
Texas Speed lists it for Gen III Hemi engines, with its engine filter covering the 5.7L VVT, 6.2L and 6.4L. Because it replaces the VVT phaser, it applies to the 2009 and newer phaser-equipped engines.
What is the advantage of a 3-bolt cam gear over a VVT lockout?
Texas Speed states the three-bolt design gives a stronger camshaft mounting system, reduces the risk of sheared dowel pins caused by single-bolt torque issues and is easier to install than a traditional VVT lockout.
Is tuning required after a 3-bolt cam conversion on a Hemi?
Yes. Removing the VVT phaser and installing a performance camshaft changes how the engine runs, so a custom tune is required after any camshaft swap.
