Frequently Asked Questions
Q: What is the difference between GWK-W65Z-LW and GWK-W65Z-LW-XL?
A: GWK-W65Z-LW-XL features 3.25 x 4.5 inch wheels versus the standard 3.25 x 6.5 inch size. The XL designation refers to the wider wheel profile on this model, not the load capacity. Both are 97A polyurethane. Choose XL if your truck frame is designed for narrower wheels or if original wheels on your W65Z show a 4.5 inch width marking.
Q: How do I verify my W65Z requires the XL variant and not the standard GWK-W65Z-LW?
A: Measure the width of your current load wheels. If they measure 4.5 inches wide, order GWK-W65Z-LW-XL. If they measure 6.5 inches, order the standard GWK-W65Z-LW. Check the truck frame pocket depth as well. Improper wheel width will cause binding and uneven wear.
Q: Can I swap XL wheels onto a truck originally equipped with standard-width wheels?
A: No. The wheel frame pocket and axle spacing are designed for a specific width. Installing XL (4.5 inch) wheels on a truck designed for 6.5 inch wheels will cause the wheel to sit too far inboard, damaging the axle and frame. Always match the original wheel width.
Q: What does sealed ball bearing mean in the GWK-W65Z-LW-XL spec?
A: Sealed ball bearings have a rubber or metal shield that prevents dirt, water, and debris from entering the bearing races. This extends bearing life and reduces maintenance compared to open bearings. No greasing is required during the service life of these sealed units.
Q: Is the machined carbon steel wheel core a wear item I need to replace?
A: The wheel core is not a wear item. The polyurethane tread wears off, but the steel core is permanent. If the core becomes damaged (cracked or severely out of round), the entire wheel assembly must be replaced. You cannot re-tread or repair a damaged core.
Q: Do I need to re-torque the fasteners after the first week of operation?
A: Yes. Check all axle fasteners after 50 to 100 hours of operation and retorque to manufacturer spec (typically 45 to 55 foot-pounds depending on fastener grade). Vibration and load cycling can loosen fasteners. Re-check every 6 months during routine maintenance.
