One nut wasn’t threaded, ordered a replacement set and all was well. Followed arp instructions, used arp lube. Zero issues. ### ⭐⭐⭐⭐⭐ 2001 4.8L *by K***T on 15 January 2024* Fit my 2001 gmc sierra 1500 with the 4.8l vortec. Good option for a stock replacement. Does not come with torque gease. I followed arp's torquing instructions ### ⭐⭐⭐⭐⭐ Holding up. Worked perfectly *by T***. on 29 March 2026* Used these on a budget rebuild on my lm7 5.3 With new 862 heads. I torqued them to arp specs last round of torque was 75ft lbs Make sure to lube the washer and nut so it torques correctly. Otherwise the nut and washer will kinda bind up during torque sequence. No issues with this kit at all. They look nice and they gave 1 extra of each length. DO NOT TORQUE TO 100FTLB GO 75FTLB AND YOUR GOOD. ## Frequently Bought Together - PQY 12-Point Cylinder Gasket Head Stud Bolts Nuts Kit Compatible with 97-03 Chevy LS1 LQ9 LS6 4.8L 5.3L 5.7L 6.0L Engines - Camshaft Retainer Plate Gasket Compatible with LS Series Engines, &Bolt Kit ARP 134-1003 Gen III IV V for GM LS1 LS2 LS3 4.8 5.3L 6.0L 6.2L Vortec Corvette Cam - Brian Tooley BTR Delphi LS7 Lifters + Trays for Gen 3 Gen 4 LS + Gen 5 LT Engines X12499225-16 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/525180171-pqy-12-point-cylinder-gasket-head-stud-bolts-nuts-kit](https://www.desertcart.hr/products/525180171-pqy-12-point-cylinder-gasket-head-stud-bolts-nuts-kit) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-26*
