1989 GMC Sierra SLT 5.7 (350 Small Block!) from North America


Minor engine mods and this truck will perform, out of the hole this truck hauls


Fuel pump.



Belt tensioner, Belt.

Upper and Lower Ball joints.

CV Joints, U Joints all around.

Pitman arm, idle arm, center link, Tie rods.


Intake manifold gaskets.

Valve cover gaskets.

Rear brake drums and shoes changed for the first time at 128,000 miles!

New Radio.

Bench seat is terrible, especially when refurbished with Vinyl... made a sharp turn and I was in the passenger seat.

Brake lights actually disintegrated, due to poor harness design.

General Comments:

I threw a paint job and chrome rims from a 2001 GM truck on this Regular cab, flare-side bedded beast and she looks great!

This truck is quick, but put in a performance air filter, (and intake... although most could opt to just flip the air cleaner cover over), and a Borla exhaust and you will not only haul tail, you'll also get better mileage.

Transmission and rear end are like a Rock, but they need regular service to maintain this. Drop the pan and filter at least ever 30,000 miles over 100,000.

I drive this truck hard! Don't think all the stuff I've replaced has been in vain, these are things that normally go wrong with older vehicles. I expect get at least another 100,000 miles out of this truck, and then put it in a garage for my son.

Would you buy another car from this manufacturer? Yes

Best truck ever


Loose ground wire caused the engine to run rough, couldn't find it, but when it was found and fixed it ran great.

General Comments:

Wish I hadn't sold it, have a 98 GMC 3/4 ton 4x4 just like it, it has been in the shop 14 times since new, the 89 wasn't in once.

I have a 1989 GMC truck 117,000 miles on it. It is a great runner! 4.3 L vortec engine .I also have a PT cruiser and it's just sitting in my garage. It doesn't have the power I'm used to...

I have a red 89 GMC Sierra Pick up and I love it!! I would never get rid of it. I am from Alaska and have drove the pickup from Alaska to Ohio. The truck has 300,000 miles on it and it still runs great. Right now its in the shop getting a new paint job and we are going to turn the truck into a hot rod. My girlfriend has asked me to sell the truck because we have 2 kids but she has a car so I dont see any reason to get rid of the truck. I take it to work and on weekends we take the truck for a drive for cruising. Everyone always makes comments about my truck. I also named my baby girl Sierra after the truck.
