The package includes two precisely machined aluminum blocks, four galvanized U-bolts, lock washers and nuts sized to fit the blocks, plus clear installation guidance. Built for durability and corrosion resistance, the components are intended to provide a clean, factory-like fit while reducing ride height and improving stance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this lowering block kit reduce ride height?\u003c\/h3\u003e\n\n\u003cp\u003eThe lowering block replaces the standard spacer between the axle and the leaf spring perch to move the spring mounting point upward relative to the axle, creating a 3-inch drop in rear ride height. Installation repositions the spring center over the axle using the supplied U-bolts and fasteners, maintaining secure attachment and alignment.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e3-inch drop per kit when installed per vehicle specifications\u003c\/li\u003e\n  \u003cli\u003eTwo extruded aluminum blocks for consistent, even lowering\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel U-bolts sized 3\" x 10\" for secure clamping\u003c\/li\u003e\n  \u003cli\u003eAll necessary lock washers and nuts included\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and corrosion protection are used?\u003c\/h3\u003e\n\n\u003cp\u003eRacewill uses extruded aluminum for the blocks to achieve high strength with reduced weight, resisting deformation under load.

Racewill offers multiple height options across the product line; this particular kit provides a 3-inch lowering block, and other heights are available if you need a different drop for clearance or stance.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eCompatible with most standard leaf spring rear axles; confirm perch dimensions first\u003c\/li\u003e\n  \u003cli\u003eMeasure axle-to-frame and brake\/drive shaft clearances before selecting height\u003c\/li\u003e\n  \u003cli\u003eConsult a professional installer or Racewill fitment guide for exact match\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat comes in the box and what should a professional installer know?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit ships complete with two machined blocks, four galvanized U-bolts (3\" x 10\"), eight lock washers and eight lock nuts so you have everything to secure the spring to the axle.

The Racewill 3\" Lowering Block Kit is aimed at truck and SUV owners who want a modest rear drop for improved stance or lowered load height while preserving leaf spring reliability. Choose this kit if your vehicle uses a conventional leaf-spring axle and you prefer a durable, corrosion-resistant solution supplied with complete hardware. If you need a different drop or have uncommon perch dimensions, verify fitment with Racewill or a professional installer before purchasing.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I install this lowering block kit myself?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Basic mechanical skills might suffice, but professional installation is recommended to ensure correct torque, alignment, and safety.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will a 3\" lowering block affect my brakes or driveshaft?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It can change angles and clearances; verify brake line and driveshaft clearance before installation and consult a technician.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Racewill","offers":[{"title":"Default Title","offer_id":48080925622430,"sku":"B0DG8FGTR3","price":87.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/racewill-front-packaging-blocks.jpg?v=1785792480","url":"https:\/\/northtrailauto.ca\/products\/racewill-3-inch-leaf-spring-lowering-block-kit-3-rear-drop-extruded-aluminum-hardware","provider":"North Trail Auto","version":"1.0","type":"link"}
