This kit fits Mid-2004 and newer LS engines which have 10 head bolts all the same length on each side. Will NOT fit earlier blocks which have 8 longer and 2 shorter bolts per side.
ARP2000 series is a step up in strength vs the standard ARP Head Studs, ideal for boosted & nitrous applications.
Be sure to note which head bolts you need as GM used two different style LS head bolts:
1997-2003 heads used QTY 8 155mm Bolts, QTY 2 100mm bolts, and QTY 5 45mm bolts
2005-2014 heads used QTY 10 100mm bolts, and QTY 5 45mm bolts
Finish: Black oxide
Made in the USA
100% of fastener manufacturing is in-house at ARP
