1911 Ignition Kit – Extreme Engineering LiteSpeed II-5 Piece

Extreme Engineering LiteSpeed II – 1911/2011 Ignition Kit (5-Piece)

Upgrade your 1911 or 2011 competition pistol with the Extreme Engineering LiteSpeed II Ignition Kit. Because this kit focuses on the hammer, sear, disconnector, and springs, it transforms trigger performance. Consequently, you experience cleaner, lighter, and more consistent trigger pulls compared to relying on the trigger shoe alone.

Why the LiteSpeed II Kit Outperforms Factory Parts

Superior Materials and Durability

Most factory fire-control parts use basic induction heat treatment. As a result, they wear quickly, lose their hardened surface when tuned, and often produce heavy, gritty, or inconsistent pulls.

In contrast, Extreme Engineering crafts each LiteSpeed II component from aerospace-grade steel—the same material used in rocket booster engines. Therefore, these parts resist wear, maintain precise geometry, and provide exceptional strength. Moreover, the parts arrive perfectly machined, eliminating the need for stoning or polishing. Consequently, shooters get a reliable, consistent, and competition-ready trigger right out of the box.

Competition-Ready Performance

Right out of the box, this kit delivers a clean 3-lb trigger pull. With minor adjustment to the included sear spring, you can tune the trigger down to 2¼-lb for match-level precision. Because the parts maintain their geometry under repeated use, the trigger pull remains consistent through thousands of rounds.

Furthermore, Extreme Engineering backs every kit with a lifetime warranty against breakage. Therefore, shooters gain both confidence and long-term value. In contrast, many imported kits rely on inconsistent materials and poor heat treatment, producing unreliable triggers over time.

Key Components of the LiteSpeed II Ignition Kit

LiteSpeed II Chamfered Hammer

This ultra-light hammer weighs only 0.3 oz. Consequently, it reduces lock time and improves split-second responsiveness during rapid fire. Additionally, heat-treated to 50–54 RC, it provides long-lasting durability. The hammer fits Kimber, Springfield, Colt, STI, SV, Para, and Springfield Prodigy platforms.

Ultra Low-Mass Sear

Made from the same aerospace alloy as the hammer, this re-contoured low-mass sear delivers faster reset and lighter trigger pulls. Its micro-honed surface allows for an effortless 2-lb break when tuned. Because it is heat-treated to 53–56 RC, the sear resists wear and prevents trigger follow during rapid fire.

Ultra Low-Mass Race Disconnector

This lightweight disconnector ensures consistent resets and reduces the chance of misfires during fast double-taps. Therefore, it enhances cycling reliability in high-speed competition setups.

Thunder Mountain Custom Light Sear Spring

Included exclusively with this kit, the custom Light Sear Spring delivers a clean, crisp break. As a result, shooters can achieve lighter trigger weights without sacrificing safety or reliability.

Wolff Precision Mainspring (Choice of 15, 17, or 19 lb)

Choose the mainspring weight that matches your preferred trigger feel and ignition reliability. Wolff springs provide consistent performance and long-term durability. Consequently, your pistol maintains optimal function round after round.

Installation and Notes

Some pistols may require minor fitting of the thumb safety. In certain cases, the existing safety may not engage the new sear properly. Therefore, you may need to install a new thumb safety to ensure safe and reliable operation.

Why Competitive Shooters Choose LiteSpeed II

The LiteSpeed II Kit targets serious competitors who demand ultra-light hammers, fast lock times, and the freedom to tune triggers to match-level precision. Furthermore, aerospace-grade materials, precise machining, and a lifetime warranty make this kit ideal for 1911 and 2011 pistols built for competition.

Because the kit improves speed, control, and consistency, shooters gain a measurable edge in performance. Consequently, it works perfectly in Springfield Prodigy, STI, SV, Colt, Kimber, and custom 1911/2011 competition builds.
