1981 GMC Sierra 1500 Description

This is the GM square body 4x4 you have been waiting for! Black on Black 1981 GMC High Sierra 1500 4x4 that drives better than it did when it was brand new. Last owner had is since 2001 and was an ASE certified master mechanic who did all of the upgrades listed below. The truck has been repowered with a 2006 Chevy 5.3LS fuel injected V8 as well as the 4L60E four speed overdrive automatic transmission which came from a 2006 Chevy Avalanche which was hit in the back. The donor truck had approx 99k original miles, and replaced a 305 V8 / Turbo 350 combo. The swap was completed approximately four years ago and since has had about 6,000 mile put on it, the truck has been garaged, and at times has been and can be a daily driver no problems, has been drive to car shows that were a hundred or more miles away at times. The swap was done using a custom ECM and custom harness, which works with the factory gauge cluster and gauges which are all operational. The truck has factory dual 16 gallon gas tanks selected by a transfer switch and has dual corvette electric fuel pumps, one for each tank, also operating off a switch on the dash. The modern A/C system was used, including the 2006 compressor and custom lines were made, and charged with R134A refrigerant and works fantastic.
Interior - The truck has new black OE style carpet with underlayment, new black cloth style headliner, and new black carpet dash cover, factory vinyl dash cover underneath is cracked. The seat is from a later model truck, gray cloth fabric, and helps break up the otherwise all black interior, each seat flips forward, and both slide forward and back indepentently and are very firm, supportive and comfortable. The truck has manual windows and locks as well as rear slider window all of which work properly. Pioneer CD player and speakers.
Drivetrain - The engine and transmission were installed using an Advance Adapters kit to mount and correctly clock the factory transfer case which is retained in its stock location allowing the use of standard factory length driveshafts. The truck has never been lifted, and drives just like a stock truck handling very well. New steering gear box just installed, drives straight down the road, stops properly. Tires are brand new 31x10.50x15 Cooper Discover AT installed on the factory GMC aluminum wheels. New underhood insulation. Full custom dual exhaust with H crossover pipe, exiting out the back of the truck, nice tone, more on the quiet side, not loud or obnoxious. New battery just installed, over the years the truck was maintained as needed, only item we can see now is a slight leak at the front pinon seal on the rear differential, leaves a quarter size spot of oil over about 6 months. The truck has been in storage on and off, and even after sitting for a six month period, its hit the key and go, it has been very reliable and trouble free.
Exterior - The truck has lived in Arizona its entire life and has had owners who took excellent care of the truck, the last owner had it for nearly 16 years. No rust on the truck at all, this is the one you have been looking for and rust belt folks would probably kill for, truck was repainted gloss black by a local body approximately four years ago. The truck has been driven, daily at times, but cared for and garage kept, does have a few rock chips along the lower rocker panels, behind the fenderwells, one small blemish on drivers door on the body line just behind the fender emblem, about the size of two dimes, has been touched up, and well as two blemishes on the front wiper cowl near the rear corners of the hood. Black is a tough color to maintain in Arizona, but this one looks good, good enough for a local car show or cruise night.
