AW-17220743903, GT-K4ZB5X3V
Tighten up steering feel and level heavy loads on your First-Gen D250/D350 or W250/W350. CPP Diesel stocks steering shafts & couplers, shocks, leaf-spring bushings, helper springs, air bag kits & onboard air, traction bars, and hardware chosen for the 1989–1993 VE-pump 12-valve.
Browse the full 1989–1993 Cummins catalog for complementary upgrades.
Start with the steering shaft and coupler. A Borgeson replacement removes rag-joint play and is a direct fit.
Bilstein 4600 monotubes are a proven upgrade; confirm 2WD vs 4WD and front/rear part numbers before checkout.
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.
Add traction bars and use weld-on brackets to control pinion angle under load.
Many items are shared, but shock lengths and some hardware differ. Always verify fitment on each product page for your configuration.
