Overview
The Daystar KT02017BK is a greaseable bolt and bushing kit for the main eyes of leaf springs, with black polyurethane bushings, gun-drilled graded bolts, zerks and nylock nuts. It is meant for do-it-yourself installers.
This kit is marked universal fit, but no specific year, model or trim is identified. Check that the leaf spring application matches the main eye you are replacing before ordering.
Key features
- Greaseable design with zerks for lubricating the bushings
- Gun-drilled graded bolts
- Black polyurethane bushings
- Nylock nuts included with the kit
Setup and hardware check
Main eye kits combine bushings, bolts and nuts, so every part of the joint should be inspected before assembly. Gun-drilled bolts let grease pass through toward the bushing bore, which is why zerks are included.
Grease zerks should be tightened snugly and kept clean, since dirt in the fitting blocks lubrication. Nylock nuts hold their grip under vibration, but they should still be checked for tightness after the first drives.
Confirm the eye size on your leaf spring before pressing parts in, and inspect the spring for cracks at the eye. Lubricate the bushings once assembled, and plan regular greasing after water crossings.
- Clean the zerks before greasing
- Check the spring eye for cracks before assembly
- Re-check nut tightness after the first drives
