Truck owners and mechanics, this Peterbilt hood bushing kit is absolutely essential for keeping your hood operating smoothly! The package includes 8 hood roller bushings in that distinctive blue color plus 2 hood bumpers, giving you everything you need for a complete hood mechanism refresh. These bushings are designed specifically for Peterbilt 357, 375, 377, and 379 models with those J-style hinges, and they cross-reference to original part numbers 13-03593 and 13-04391. The polyurethane rubber construction is seriously durable - it resists chemicals, oils, and gasoline way better than natural rubber, so you know it'll last through tough conditions. The sizes are spot-on too: the main bushings measure 1-5/8\ length with 5/8\ ID and 1-1/2\ OD, while the smaller ones are 1-1/2\ with 11/16\ ID and 1-1/8\ OD. The hood bumpers are the short bolt-on style measuring 2-3/8\ x 2\ x 3-1/8\ and cross-reference to Peterbilt part 13-03510. Installation is pretty straightforward if you're familiar with truck hood mechanisms, and the improvement in hood operation is immediately noticeable. No more sticking or rough movement - just smooth, reliable hood operation that makes your daily checks and maintenance so much easier. Definitely a must-have for any Peterbilt owner doing their own maintenance!
