Ignition Kit – Extreme Engineering – LiteSpeed II- 3 Piece

Extreme Engineering LiteSpeed II Ignition Kit – 1911 / 2011 (3-Piece)

Competition-Ready Fire-Control Upgrade for Maximum Speed

Built for Speed, Precision, and Long-Term Consistency

First and foremost, the Extreme Engineering LiteSpeed II Ignition Kit upgrades your 1911 or 2011 competition pistol with a purpose-built fire-control system designed for speed and precision. Rather than relying on cosmetic upgrades, this kit focuses on the internal components that truly define trigger quality.

Although many shooters concentrate on the trigger shoe, the real feel of the trigger comes from the hammer, sear, disconnector, and springs. Consequently, these parts determine crispness, smoothness, reset feel, and long-term consistency. Because of this, even the most expensive trigger shoe cannot correct weak materials or unstable internal geometry.

Why the LiteSpeed II Kit Outperforms Factory Fire-Control Parts

Most factory ignition systems use basic steel combined with simple induction heat treatment. As a result, durability remains limited, and safe tuning becomes difficult without cutting through the hardened surface. Over time, this leads to heavier pulls, gritty breaks, and inconsistent trigger feel.

By contrast, the LiteSpeed II Kit uses a premium aerospace alloy originally developed for rocket booster engine applications. Because of this advanced material, every component delivers exceptional strength, superior wear resistance, and long-term geometry stability.

In addition, Extreme Engineering machines each part to precise final dimensions. Therefore, no stoning of hammer hooks or sear faces is required. As a result, shooters gain a cleaner break, faster reset, and a trigger pull that stays consistent through extended competition use.

Competition-Ready Performance Right Out of the Box

Straight from installation, the LiteSpeed II Kit delivers a clean and predictable 3-pound trigger pull. However, with a minor adjustment to the included sear spring, shooters can easily achieve a stable 2¼-pound competition trigger. More importantly, because the components maintain their geometry, pull weight does not drift over time.

Furthermore, Extreme Engineering manufactures all components in the USA and backs them with a lifetime warranty against breakage. Consequently, compared to imported ignition kits that rely on inconsistent materials and questionable heat treatment, this system offers significantly greater durability and confidence.

Because the kit combines an ultra-light hammer with extremely fast lock time, it is specifically intended for 1911 and 2011 pistols built for competition use.

Exclusive Thunder Mountain Custom Advantage

Only Thunder Mountain Custom includes a precision-tuned Light Sear Spring with this kit. As a result, shooters benefit from a cleaner break, lighter pull potential, and improved consistency compared to standard ignition kits. Simply put, this exclusive spring enhances performance without sacrificing reliability.

What’s Included in the LiteSpeed II Ignition Kit

LiteSpeed II Chamfered Hammer

To begin with, the LiteSpeed II hammer maximizes speed and responsiveness.

• Ultra-lightweight design at only 0.3 oz

• Produces one of the fastest lock times available

• Heat treated to Rc 50–54 for durability

• Optimized mass improves split times and trigger response

• Fits Kimber, Springfield, Colt, STI, SV, Para, and Springfield Prodigy pistols

Ultra Low-Mass Sear

Next, the ultra low-mass sear stabilizes light trigger pulls.

• Manufactured from the same aerospace alloy as the hammer

• Re-contoured design for faster reset

• Micro-honed engagement surface for an effortless 2-pound break when tuned

• Heat treated to Rc 53–56 for outstanding wear resistance

• Helps prevent trigger follow during rapid fire

Ultra Low-Mass Race Disconnector

Finally, the race disconnector enhances reliability at speed.

• Improves reset consistency

• Reduces disconnection issues during fast double-taps

• Supports smooth, reliable cycling in high-speed competition pistols

Important Fitment Notes

In most cases, installation is straightforward. However, some pistols may require thumb safety fitting. Additionally, certain builds may need a new thumb safety to ensure proper sear engagement. Therefore, final fitting by a qualified pistolsmith is recommended for optimal safety and performance.

Built for Serious Competition Shooters

Ultimately, if you are building or tuning a match-ready 1911 or 2011, the Extreme Engineering LiteSpeed II Ignition Kit delivers faster lock time, cleaner breaks, lighter and stable pull weights, and long-term consistency. Thanks to aerospace-grade materials, precision machining, a lifetime warranty, and the exclusive Thunder Mountain Custom sear spring, this kit provides elite-level fire-control performance that holds up through thousands of competitive rounds.
