Overview
The Tuff Country Ladder Bars 10890 are rear ladder bars for lifted Chevrolet and GMC K-series trucks from 1988 to 1998, with the GMC K2500 listed through 2000. Ladder bars like these reduce the wheel hop and axle wrap that can follow a lift when larger wheels and tires are added.
The ladder bars are a direct fit, bolt-on rear upgrade intended for better traction and handling on a lifted truck.
Key features
- Ladder bar design for increased traction
- 1.25 inch tubing
- Powdercoated black finish for durability
- Direct fit, bolt-on mounting
- All required mounting hardware included
Ladder bars and axle location
A ladder bar fixes the axle’s fore-and-aft position and limits how far it can twist under acceleration and braking. Lifted trucks with larger tires can wind the axle, so a ladder bar helps keep the driveline stable. Mounting points on the frame and axle should be checked for cracks and loose bolts after the first drives.
Ladder bar length and mounting angle affect pinion angle, so alignment and driveline angles should be checked after installation. Bushings at each end of the bar wear over time, and worn bushings let the axle move more than intended. When replacing bars, consider the shock and spring mounts, since these are often inspected at the same time.
- Check pinion and driveline angles
- Inspect bushings for wear
- Look for cracks at frame mounts
