Featuring high-strength Grade 8 bolts, rust-resistant yellow zinc finish, and a perfect fit for factory 9/16” holes, it includes all necessary hardware plus an extra M14 bolt for 2012+ JKs. Made in the USA, this kit ensures enhanced durability, safety, and performance for serious Jeep enthusiasts. ## Description This must-have upgrade will put your mind at ease. This kit will fix the design flaw caused by the stock bolts. The problem arises because the holes for the tracks bars (TB) are 9/16” while the factory bolts are 14mm. This creates a small clearance issue. The other issue is the factory bolts are completely threaded to the head. The threads come into contact with the metal sleeve in the bushing. Both of these factors will cause the bushing sleeve to wear down and become loose over a fairly short period of time causing damage and eventually death wobble. Our upgrade kit provides everything you need to replace the bolts for the Front Track Bar, and Rear Track Bar. New bolts will match factory 9/16” holes and new bolts have shoulder to prevent threads from coming into contact with bushing. Kit contains high strength Grade 8 hardware. Includes hardened extra thick washers (2 per bolt) that will not deform like standard washers and hex locking nuts. All hardware is yellow zinc to prevent rust. We also include (1) M14 Bolt for the Front Frame Side Track Bar Bracket for newer 2012+ Jeep JKs JKUs. ## Features - Front & Rear Track Bars Bolts will fix issues caused by stock bolts - High-strength Grade 8 hardware - Includes bolts, lock nuts, and washers for installation; Includes extra M14 bolt for 2012+ JKs and JKUs Front Frame Side Track Bar Bracket - Compatible with Jeep Wrangler JK model years 2007-2018 - Made in U.S.A ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B018Q6FIQ0 | | Best Sellers Rank | #457,502 in Automotive ( See Top 100 in Automotive ) #28 in Automotive Replacement Chassis Track Bar Hardware & Parts | | Brand | Ohio Diesel Parts | | Color | Copper | | Compatible Groove Diameter | 0.56 Inches | | Customer Reviews | 4.7 out of 5 stars 428 Reviews | | Drive System | 4-Wheel Drive | | Exterior Finish | Yellow Zinc | | Fastener Size | 5/16 inches | | Fastener Type | Hexagon Bolt | | Finish Types | Plated | | Grade Rating | Grade 8 | | Head Style | Hex | | Item Diameter | 14 Millimeters | | Item Dimensions | 7.48 x 7.48 x 11.81 inches | | Item Hardness | Grade 8 | | Item Weight | 1 Pounds | | Manufacturer | Ohio Diesel Parts | | Manufacturer Grade | Grade 8 | | Material | Alloy Steel | | Material Type | Alloy Steel | | Maximum Shear Strength | 82.5-87 ksi (estimated) | | Metal Type | Zinc | | Number of Pieces | 6 | | Part Number | JBK-1500S | | Screw Head Style | Hex | | Set Name | Track Bar Bolt Suspension Upgrade Kit | | Set Screw Thread Type | Metric | | Size Name | 14mm | | Thread Class | 3A | | Thread Coverage | Partially Threaded | | Thread Size | M14 | | Thread Style | Right Hand | | Thread Type | Metric | | Unit Count | 1.0 Count | ## Product Details - **Material:** Zinc - **Thread Size:** M14 - **Exterior Finish:** Yellow Zinc - **Manufacturer Grade:** Grade 8 - **Head Style:** Hex ## Images ![Track Bar Bolt Suspension Upgrade Kit Compatible with Jeep Wrangler JK + Extra M14 Bolt - Image 1](https://m.media-amazon.com/images/I/71xOyfMT2RL.jpg) ![Track Bar Bolt Suspension Upgrade Kit Compatible with Jeep Wrangler JK + Extra M14 Bolt - Image 2](https://m.media-amazon.com/images/I/81W4dW4snYL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***S on May 10, 2018* ### ⭐⭐⭐⭐⭐ Review *by A***S on July 7, 2020* ### ⭐⭐⭐⭐⭐ Review *by H***Z on May 27, 2022* --- ## 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.vn/products/21783592-track-bar-bolt-suspension-upgrade-kit-compatible-with-jeep-wrangler](https://www.desertcart.vn/products/21783592-track-bar-bolt-suspension-upgrade-kit-compatible-with-jeep-wrangler) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
