Buying Guide

Confirm vehicle fitment

Verify year, model, and bed/cab configuration to match extenders or mounts to your Silverado/Sierra or compatible chassis

Match extension length and travel

Choose extenders rated for the required lift or drop (for example 4–6 inch extensions) to preserve shock travel and geometry

Prioritize steel and weld quality

For weld-on tabs and mounts, select heavy-gauge steel and clean weld profiles for long-term durability under load

Check adjustability and kit completeness

Adjustable extenders and mounting kits that include hardware and bushings simplify installation and reduce additional purchases

Assess spare tire and crossmember fit

If modifying rear mounts, ensure spare tire support plates or crossmember adapters maintain clearance and mounting integrity
