Everything you need to properly install injectors in your LB7 engine.
The kit includes:
Injectors – LB7 2001-2004.5 Chevrolet/GMC 2500/3500/4500/5500 6.6 Diesel Vin Code “1”
These Refurbished & tested LB7 injectors are Bosch injectors that are reconditioned in-house. The Updated Body option features an updated body that corrects cracking issues that were common in early LB7 injectors.
They are cleaned externally in an ultrasonic tank, flushed internally, and the nozzles are reconditioned. Each injector is Individually tested on a state of the art test stand to ensure that they meet OEM specifications. Each test includes a resistance test, system leak test, purge, idle speed test, mid load test, full load test, and static back leak test. Each test cycle checks solenoid response time, back leak flow, and fuel delivery. Guaranteed to be within factory specification.
