Crucially, you need to check the compressor's specifications: Look for the manufacturer's stated capacity in terms of pounds (lbs) or tons of compression force. A GMC Sierra 2500's coil springs are under considerable tension, so you need a tool rated significantly higher than that tension to ensure safety. Using a tool that's too weak is extremely dangerous and could result in serious injury from spring failure.
Do not rely on a part number alone. Find the manufacturer's documentation for part 27035 or contact the supplier to confirm its suitability for a GMC Sierra 2500's heavy-duty springs. If you can't find this information, it's best to err on the side of caution and choose a different, heavier-duty compressor designed explicitly for trucks. Your safety is paramount.
