2011 Peace, mercy, and blessings of God be upon you. I am offering a GMC Sierra with 600,000 km mileage. Engine: V8 aluminum 6.0L. Engine mileage: 150,000 km. Wiring harness modified at Al-Harabi factory. Imported transmission. Differential lock is working but needs maintenance and the driveshaft needs to be removed. The car needs minor maintenance: the relay box needs replacement, a dyno tune, the hood is faded, and the roof is faded. The car has been fully repainted. Additions: Four lights around each tire, a hidden tank with a faucet under the driver's door, a switch for the auxiliary lights, a muffler with a pleasant, soft sound with a single connection from the exhaust to the muffler, Denali exhaust manifolds, Denali fuel pump, and a 40,000 BTU transmission cooler.
