Buying Guide

Match kit to vehicle and year

Confirm the kit's listed fitment for your make, model and model years—axle flip kits and lowering links are specific to truck platforms (Silverado/Sierra, C10/C15) and motorcycles (GROM, Harley Touring)

Decide desired drop and ride height

Choose a kit that provides the targeted drop (examples in this category range from about 1.5" to 6") to maintain intended clearance, driveline angles, and appearance

Consider suspension type and components

Match the kit to your suspension system—leaf spring lowering blocks vs. axle flip kits vs. lowering links have different effects on ride quality, load capacity, and alignment needs

Check build materials and hardware

Look for durable materials and complete hardware packs; solid brackets, plated bolts or hardened steel components improve longevity under load and exposure

Plan for alignment and associated work

Many lowering modifications require a post-install alignment and inspection of driveline, brake lines, and suspension geometry to prevent premature wear
