Extreme Engineering LiteSpeed II – 1911/2011 Ignition Kit (5-Piece) | Competition-Ready Fire Control Upgrade

Upgrade your 1911 or 2011 competition pistol with the Extreme Engineering LiteSpeed II Ignition Kit, a high-performance fire-control system built for shooters who demand speed, precision, and long-term reliability. Many shooters focus only on the trigger shoe; however, the real feel of your trigger pull comes from the hammer, sear, disconnector, and springs. These parts determine the crispness, smoothness, and consistency of every shot. Because of this, even an expensive trigger shoe cannot fix low-quality internal parts.

Why the LiteSpeed II Kit Outperforms Factory Parts

Most factory fire-control components use simple induction heat treatment. This limits their durability and prevents you from tuning or stoning them without removing their hardened surface. Over time, the trigger pull often becomes inconsistent, heavy, or gritty.

In contrast, the Extreme Engineering LiteSpeed II Kit uses a premium aerospace alloy—the same material used in rocket booster engine applications. This advanced steel offers exceptional strength, wear resistance, and stable geometry. Additionally, the parts come perfectly machined, so you don’t need to stone the hammer hooks or sear surfaces. As a result, you get a cleaner, lighter, and longer-lasting trigger pull.

Competition-Ready Performance

Right out of the box, the kit delivers a clean 3-lb trigger pull. With a small adjustment to the included sear spring, you can set a consistent 2¼-lb competition trigger that stays stable through thousands of rounds. Because the parts maintain their geometry, the trigger pull does not drift over time.

Extreme Engineering components rank among the best in the USA. They also include a lifetime warranty against breakage, offering confidence and long-term value. Furthermore, the build quality far exceeds imported ignition kits that often rely on inconsistent materials and poor heat treatment.

This kit is designed for shooters who want an ultra-light hammer, extremely fast lock time, and the freedom to tune their trigger to match-level precision. Therefore, it is intended only for 1911/2011 pistols used in competition.

Only Thunder Mountain Custom includes a custom “Light” Sear Spring, which gives you a cleaner and lighter pull than standard springs included in similar kits.

⭐ What’s Included in the LiteSpeed II Ignition Kit

🔹 LiteSpeed II Chamfered Hammer

This ultra-light hammer weighs only 0.3 oz, giving you one of the fastest lock times available. Because of its low mass, your split times improve, and your trigger feels more responsive. It is heat-treated to 50–54 RC for exceptional durability. The hammer fits 1911 platforms from Kimber, Springfield, Colt, STI, SV, Para, and the Springfield Prodigy.

🔹 Ultra Low-Mass Sear

This sear comes from the same aerospace alloy as the hammer and features a re-contoured low-mass design. It delivers faster reset times and supports extremely light trigger pulls. The micro-honed surface provides an effortless 2-lb break when tuned. Heat treatment to 53–56 RC ensures top-tier wear resistance and long-term performance. Additionally, it helps prevent trigger follow during rapid fire.

🔹 Ultra Low-Mass Race Disconnector

The lightweight disconnector improves reset consistency and reduces the chance of disconnection issues during fast double-taps. It works perfectly in high-speed competition setups and helps ensure smooth, reliable cycling.

🔹 Thunder Mountain Custom Light Sear Spring

Included exclusively in this kit, this spring is tuned for a clean, crisp break. It allows you to achieve light trigger weights without sacrificing reliability.

🔹 Your Choice of Mainspring (Wolff Precision GunSprings)

Choose 15 lb, 17 lb, or 19 lb depending on your preferred trigger weight and ignition reliability. Wolff springs offer consistent performance and excellent service life.

⭐ Additional Notes

• Some shooters may need to fit the thumb safety.

• In a few cases, your current safety may not engage the new sear correctly.

• You may need to install a new thumb safety for perfect function.

⭐ Built for Serious Competition Shooting

If you are building or tuning a match-ready 1911 or 2011, the Extreme Engineering LiteSpeed II Kit gives you unmatched consistency, speed, and control. Because of its aerospace-grade materials, lifetime warranty, and ultra-precise machining, the kit provides an elite-level trigger feel that stays consistent through thousands of rounds.

This kit is ideal for shooters running platforms such as the Springfield Prodigy, STI, SV, Colt, Kimber, or any custom 1911/2011 built for top-tier competitive performance.
