ENA Ignition Coil and Module Kit — Direct-Fit DR49/LX381 Replacement for Chevy/GMC 1996–2002, 3‑Terminal Coil

ENA ignition coil and control module kit replaces factory DR49/LX381 parts to restore spark delivery and engine reliability on compatible Chevy, GMC and Pontiac V6/V8 trucks and vans.

This replacement kit from ENA pairs a three‑terminal coil pack with a matched ignition control module engineered to fit a wide range of General Motors vehicles from the mid‑1990s through the early 2000s. It is designed as a direct swap for common OE reference numbers (DR49, LX381 and related OEM codes) so you get a proper fit, bolt‑on mounting and 12V electrical compatibility without having to modify wiring or brackets.

Which vehicles will this ENA kit fit?

The kit is compatible with many Chevrolet and GMC models equipped with 4.3L V6 and 5.0L, 5.7L or 7.4L V8 engines produced between 1996 and 2007, depending on the model. Fitment covers trucks, vans and SUVs including Astro, Blazer, Express, Sierra, Silverado, S10, Tahoe, Yukon and more—check OEM cross‑reference numbers and year ranges to confirm. Use your VIN or the vehicle fitment tool to verify exact compatibility before purchase.

• 4.3L V6 fitment: Astro, Blazer, S10, Sierra, Express (1996–2007 ranges)
• 5.0L & 5.7L V8: Silverado, Express, C/K series, Tahoe (1996–2002 & 1996–2000 windows)
• 7.4L V8: heavy‑duty C/K trucks and Express 3500 (1996–2000)
• Cross‑references: DR49, DR‑4910489421, LX381, and several OEM part numbers

How does installation and fitment work for this replacement kit?

ENA built this ignition coil and control module to match original mounting points and terminal counts so installation is typically bolt‑on with standard hand tools. The coil has three output terminals and a bolt‑on mounting flange; the control module uses a four‑terminal connector and is also secured with bolts. For a trouble‑free swap, park on level ground, disconnect the battery, follow service manual torque specs, and confirm connector engagement.

• Coil: 3 terminals, bolt‑on mount, 12V system compatible
• Module: 4 terminals, bolt‑on attachment, plastic/composite housing
• Includes: one ignition coil and one control module; 12‑month warranty
• Tip: confirm fit with online vehicle lookup or VIN before ordering

What performance and durability features does the ENA unit provide?

The kit is constructed from materials comparable to OE parts and uses a two‑wire bond interconnect system plus a lead frame for reliable electrical connections. While it doesn’t change engine output, it restores proper spark distribution and consistent ignition timing behavior when replacing failed or degraded original components. ENA also offers a 12‑month warranty for added confidence in materials and workmanship.

• Durable composite housing and reinforced internal interconnects
• Designed to meet OE terminal layouts and voltage requirements (12V)
• Restores consistent spark delivery and reduces misfire risk from bad coils/modules
• Backed by a 12‑month warranty for parts replacement

Who is this for? If you own a late‑1990s to early‑2000s Chevrolet, GMC or related GM vehicle and you’re experiencing misfires, rough idle, reduced drivability or you need a like‑for‑like replacement for DR49/LX381 part numbers, this ENA coil and ignition module kit is a practical, cost‑effective repair option. It’s aimed at DIY mechanics and professional technicians seeking a reliable direct replacement without custom wiring or modifications.
