This OEM-grade 87mm throttle body is a direct throttle body replacement for Cadillac Escalade/Escalade ESV and Chevrolet Avalanche, Silverado 1500, and Express 1500/2500/3500 with GM V8 engines. Engineered to GM OEM specifications, it resolves common throttle body symptoms including rough idle, engine hesitation, stalling, reduced power, and throttle lag — common issues on high-mileage GM V8 trucks and SUVs that often prompt throttle body cleaning or full replacement.
- OEM-Grade Throttle Body – Direct bolt-on replacement, no wiring or programming required for most models.
- 87mm Precision Bore – Factory-correct diameter for GM V8 truck and SUV applications.
- Dual Redundant Throttle Body Sensor (TPS) – Prevents idle fluctuations, hunting, and false error codes.
- Throttle Body Gasket Compatible – Fits standard GM OEM gasket for a clean, leak-free seal.
- Viton Seals – Oil-resistant fluorine rubber for long-term airtight fitment.
- 100% Factory Tested – Thermal cycling, airtightness, and full-stroke angle calibration before shipment.

Professional installation is strongly recommended. On GM V8 platforms, a throttle body relearn (idle relearn) procedure is required after fitting this throttle body replacement — disconnect the battery for 10 minutes or use a compatible GM scan tool to reset the ECM idle position. If the original unit had heavy carbon deposits, perform throttle body cleaning of the intake manifold before installation. Do not spray abrasive cleaners directly on the new throttle body bore or butterfly valve.
