Helpful Notes

  • Common slop sources: worn rag joint/steering shaft, tired box, and loose linkage. Shafts like the Borgeson are a popular first fix.
  • Shocks by configuration: verify 2WD vs 4WD and stock vs lifted height before ordering (see Bilstein 4600 fitment pages).
  • Towing support: choose helper springs (Hellwig) or air bags (Firestone 2071, Air Lift 88215).
  • Axle wrap: leaf-spring trucks benefit from traction bars and proper bracket placement.

Frequently Asked Questions

What’s the fastest way to tighten steering on a First-Gen?

Start with the steering shaft and coupler. A Borgeson replacement removes rag-joint play and is a direct fit.

Which shocks work best at stock height?

Bilstein 4600 monotubes are a proven upgrade; confirm 2WD vs 4WD and front/rear part numbers before checkout.

Should I choose helper springs or air bags for towing?

Helper springs are simple and maintenance-free. Air bags like Ride-Rite 2071 or Air Lift 88215 let you fine-tune support and keep the truck level when loaded.

How do I address axle wrap on launch or with heavy trailers?

Add traction bars and use weld-on brackets to control pinion angle under load.

Do these parts fit both D250/D350 (2WD) and W250/W350 (4WD)?

Many items are shared, but shock lengths and some hardware differ. Always verify fitment on each product page for your configuration.
