Amazon claimed it would not fit my 2004 Suburban, but I bought it anyway because it looked strong and no one offers an angled rear extension. It fits perfectly. On the rear, the bottom must be angled, or it will bind if it fits at all. ## Frequently Bought Together - KSP 4"-6" Shock Extenders Fit Silverado Sierra 1500, Shock Extension Kit for 1999-2006 Chevy Silverado GMC Sierra 1500 All Cabs, Rear Lowering Shock Mount Drop Shock Brackets - Belltech 8510 Pair of Rear Nitro Drop 2 Shock Absorbers for Silverado Sierra RWD 4WD - JY PERFORMANCE 6" Drop Axle Flip Kit Lowering Kit For Chevrolet Silverado GMC Sierra 1500 1999-2007 --- ## 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.tn/products/537493694-ksp-4-6-shock-extenders-fit-silverado-sierra-1500-shock](https://www.desertcart.tn/products/537493694-ksp-4-6-shock-extenders-fit-silverado-sierra-1500-shock) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-14*
