82-97 GM 6.2L + 6.5L Gator Heavy Duty Main Stud Kit

If you are wanting to keep your 6.2L or 6.5L Chevy/GMC Diesel on the road for the long haul, you need to replace your main bolts with upgraded main studs.
• Fits 1997 and earlier 6.5L turbo engines, 6.5L non-turbo engines and 6.2L engines.
• Drastically reduces the chances of main webbing cracks

Includes
-(20) 12mm Studs
-(20) 12mm 12 Point Nuts
-(20) 12mm Washers


* For 1997.5 and later engines, check your block casting number to see if its still a 599 block. If it is a 599 block this kit will work
* This kit will not fit 506 blocks, as they would require (6) 10mm studs.

These main studs have a much higher strength and will not stretch like the factory bolts will.
