Request corrosion data (ASTM B117 hours), oil viscosity\/VI (ASTM D445\/D2270), and drop\/transport tests (ISTA) for reseller logistics.<\/li>\n\n\n\n<li>Q: What KPIs prove heavy-duty kits deliver ROI for resellers and fleet clients?<br>A: Track 90-day return rate, warranty claims per 1,000 units, on-time-in-full (OTIF), install time variance, vertical acceleration RMS improvement on pilot vehicles, ESC\/ABS events per 1,000 km, and tire temperature spread.<\/li>\n\n\n\n<li>Q: How should resellers spec heavy-duty suspensions for EV upfitters?<br>A: Use rebound-biased damping maps, higher-flow pistons, and validated cold\/hot dyno curves (\u2264\u221220\u00b0C and \u2265110\u00b0C). Confirm ride-height targets to protect ADAS, and publish calibration SOPs for cameras\/radar post-lift or load changes.<\/li>\n\n\n\n<li>Q: What documentation should accompany private-label heavy-duty kits?<br>A: Fitment matrix by VIN\/variant, torque-at-ride-height SOPs, alignment under load guidance, dyno plots with gas charge (if applicable), QR-linked batch traceability, corrosion certification, and installer quick-start guides.<\/li>\n\n\n\n<li>Q: How often should heavy-duty shocks be serviced under harsh duty cycles?<br>A: Racing: inspect every event, rebuild 40\u201380 hours; fleets\/overland: inspect 20\u201330k km, replace seals\/oil as needed; RVs: seasonal checks or every 15\u201320k km.
