Basically the LS truck equivalent of caffeine and bad decisions.

The Texas Speed Chopacabra Truck Camshaft Install Kit is a whole upgrade package designed for 1999–2013 LS-based truck engines including 4.8L, 5.3L, 5.7L, and 6.0L platforms. This premium kit includes the iconic TSP Chopacabra Camshaft, a full set of Delphi LS7 hydraulic roller lifters, new LS lifter guide trays, and a matched pair of LS1 multi-layer steel (MLS) head gaskets for reliable sealing and long-term durability.

Why the Chopacabra Became So Popular

The Chopacabra gained legendary status because it delivers:

• Massive idle chop
• Strong torque
• Excellent drivability
• Great street performance

Without requiring:

• Extreme compression
• Massive RPM
• Dedicated race-car setups

It became wildly popular in:

• Street trucks
• Daily drivers
• Roll racing builds
• Budget LS swaps

Because apparently the entire LS community collectively decided smooth idle quality was suspicious.

Engineered for clean installation and precise valvetrain operation, each and every component is selected to take care of proper lifter preload, stable valve regulate, and OEM-level sealing.

Aggressive Idle Sound

Let’s address the obvious reason first:

• The sound

The Texas Speed Chopacabra Cam Kit produces:

• Heavy chop
• Deep lope
• Aggressive startup behavior

Basically transforming ordinary trucks into:

• Parking lot celebrities
• Cars & coffee distractions
• Noise ordinance discussions

Because calm idle behavior simply isn’t part of the Chopacabra experience.

Designed for LS truck owners performing a fresh build, cam upgrade, or full top-end refresh, this kit combines trusted Texas Speed engineering with high-quality OE-grade components to make sure consistent performance and dependable operation in day-to-day-driven or enthusiast-built engines.

Strong Low-End Torque

Unlike some high-RPM race cams, the Chopacabra is designed to maintain:

• Excellent low-end torque
• Strong midrange response
• Street-friendly power delivery

Perfect for:

• Heavy trucks
• Daily driving
• Roll racing
• Stoplight fun

Because LS trucks spend far more time street driving than screaming at 7,500 RPM.

Texas Speed Chopacabra Truck Camshaft: Proven cam profile designed for strong low-end torque, mid-range power, and aggressive LS truck performance even as maintaining reliable valvetrain behavior.

Includes Genuine Delphi LS7 Lifters

The Texas Speed Chopacabra Cam Kit includes:

• Genuine Delphi LS7 lifters

Benefits include:

• Excellent durability
• Quiet valvetrain operation
• Improved reliability
• OEM-quality performance

This is extremely important during:

• Camshaft upgrades
• Fresh engine builds
• High-mileage refreshes

Because reusing questionable old LS lifters during a cam swap is basically engine roulette.

Includes Delphi LS7 Lifters (Set of 16): Genuine Delphi hydraulic roller lifters deliver superb durability and quiet valvetrain operation—ideal for fresh builds and cam installations.
LS Lifter Guide Trays Included: OEM-style lifter trays keep lifters properly aligned for smooth lifter motion, reduced wear, and stable operation at all RPM ranges.

LS Lifter Trays Included

The kit also includes:

• LS lifter guide trays

These help:

• Maintain proper lifter alignment
• Reduce valvetrain wear
• Improve stability
• Support smooth operation

Especially important under:

• Higher RPM
• Aggressive cam profiles
• Performance tuning

Because lifters wandering around freely inside an LS engine would be extremely unfortunate.

LS1 MLS Head Gaskets (Pair): High-quality multi-layer steel head gaskets provide superior combustion sealing and long-term reliability, ideal for refreshed or upgraded LS truck engines.

MLS Head Gaskets Included

The Texas Speed Chopacabra Cam Kit also includes:

• LS1 MLS head gaskets

Helping simplify:

• Cam installs
• Top-end refreshes
• Complete LS upgrades

Because halfway through an LS teardown is the worst possible moment to realize you forgot head gaskets.

Complete Install Package: All key components of a top-end LS cam install are included, making this a reliable, comprehensive solution for cam upgrades, maintenance, or rebuilds.
Note: Because of supply shortages at Texas Speed, these kits would possibly ship with Michigan Motorsports Valve Springs

Great for Street Truck Builds

The Chopacabra cam works especially well in:

• Street trucks
• Daily drivers
• Naturally aspirated builds
• Mild turbo setups

Perfect with:

• Long tube headers
• Cold air intakes
• Upgraded exhaust systems
• Stall converters

Because cammed Silverado culture is basically an entire automotive subgenre now.

Excellent Horsepower & Torque Gains

The Chopacabra profile helps improve:

• Airflow
• Cylinder filling
• Midrange power
• Overall LS responsiveness

While still maintaining:

• Strong drivability
• Street manners
• Usable RPM range

Basically enough aggression to sound insane without becoming completely miserable in traffic.

Final Thoughts

The Texas Speed Chopacabra Cam Kit remains one of the most recognizable and popular LS truck camshaft packages thanks to its aggressive idle, strong low-end torque, and excellent street performance.

With genuine Delphi LS7 lifters, lifter trays, MLS head gaskets, and proven Texas Speed camshaft engineering, this kit delivers serious LS performance and unmistakable sound for truck enthusiasts everywhere.

Because eventually every LS owner decides their truck should idle like it’s preparing for battle.
