The Texas Speed Dual Spring Cam Package supplies the core parts for a camshaft upgrade on LS3, L92, LSA and L76 rectangular-port engines. It combines your choice of Texas Speed LS3 camshaft with the TSP .660" dual spring kit, built on PAC polished dual springs with retainers, new spring seats and new valve stem seals, plus Texas Speed hardened chromoly pushrods in the length selected at ordering.
The camshaft list runs from the L92 truck cams and Stage 1 through Stage 4 naturally aspirated LS3 grinds to the Honey Badger, Chopacabra, Chop Monster, Bald Eagle, turbo, centrifugal and positive displacement supercharger cams and stroker and 3/4 race grinds. Factory LS3 engines use a single-bolt camshaft; a three-bolt cam can be run with the appropriate 4X three-bolt conversion, offered as an optional timing set. AFM/DOD must be removed on equipped engines, with delete parts sold separately. A tune is required, and an HP Tuners MPVI4 or Throttle Republic tuner with tune can be added.

Ordering Options

FAQ
What is included in the Texas Speed Dual Spring Cam Package for LS3 heads?
The package includes your choice of Texas Speed LS3 camshaft, the TSP .660" dual spring kit with PAC polished dual springs, retainers, new spring seats, new valve stem seals and Texas Speed hardened chromoly pushrods in the length selected.
Which engines does this rectangular-port cam package fit?
Texas Speed lists it for LS3, L92, LSA and L76 rectangular-port applications, such as the 2010 to 2015 Camaro SS, 2008 to 2013 Corvette, 2009 to 2015 CTS-V, Pontiac G8, Chevrolet SS and 6.0L and 6.2L rectangular-port GM trucks and SUVs.
Does the Dual Spring Cam Package work on a factory single-bolt LS3 cam?
Yes. Factory LS3 engines use a single-bolt camshaft design. If a three-bolt camshaft is chosen, Texas Speed notes a 4X three-bolt conversion is required and offers a 3-bolt timing set as an add-on.
Do I need to delete AFM or DOD before installing this cam kit?
Yes, on engines equipped with AFM/DOD such as the L99 and some L76 and L92 trucks. Texas Speed states AFM/DOD must be removed and sells the delete components separately.
Why does this kit use .660" dual springs?
The PAC polished dual springs in the TSP .660" kit support the higher lift of the Texas Speed LS3 camshaft lineup, many of which run .629" to .649" lift, with margin that single springs do not provide.
Is a tune required after installing the LS3 cam package?
Yes. A custom tune is required after the camshaft swap. Texas Speed offers the HP Tuners MPVI4 or its Throttle Republic tuner, which includes a tune, as optional add-ons.
