The Coachbuilder Polyurethane Bushing Kit replaces the rubber bushings in the rear leaf spring eyelets of 2007–2021 Toyota Tundras with a polyurethane compound that has graphite added — firm enough to control the spring, slick enough to pivot without the squeak poly is infamous for. Manufactured by Energy Suspension and CNC machined for less friction and a precise fit, the bushings are designed to give the leaf pack a smooth, controlled pivot. One hard rule from the manufacturer: these go in the spring eyelets only — do not use them in the frame rail.
Features
- Polyurethane compound with graphite added for a low-friction, quiet pivot
- CNC machined for less friction and a perfect fit in the rear leaf spring eyelets
- Designed to allow a smooth, controlled pivot as the leaf springs cycle
- Includes (4) polyurethane bushings, (2) steel center sleeves, and (1) grease pack
- Compatible with most aftermarket leaf spring packs
- Made in the USA, manufactured by Energy Suspension
- Not for frame rail use — rear leaf spring eyelet positions only
This is the same style of graphite poly bushing kit that ships inside every Coachbuilder shackle kit — if you’re lifting the rear at the same time, the Coachbuilder +2" Shackle Kit bundles bushings, shackles, and hardware together. Refreshing an existing shackle install instead? The Shackle Rebuild Kit adds sleeves and fresh hardware. Browse more bushings and leaf spring upgrades.

Coachbuilder Polyurethane Bushing Kit | Rear Leaf Spring Eyelets | Fits Toyota Tundra 2007–2021 | Ekstrom Design FAQs
Why can't I use these bushings in the frame rail?
Because the manufacturer says so, in underline: do not use in the frame rail. This kit is machined specifically for the rear leaf spring eyelet positions on 2007-2021 Toyota Tundras — the frame rail bushing location is a different job with different requirements. Install these at the spring eyelets only and leave the frame rail position alone.
Will they work with my aftermarket leaf springs?
In most cases, yes — the kit is compatible with most aftermarket leaf spring packs as well as the factory springs on 2007-2021 Tundras. To install, press the old rubber bushings out of the spring eyelets (a ball joint press makes quick work of it), grease all outer surfaces of the new bushings and sleeves with the supplied pack, and tap them in with a soft hammer.
Do I need this kit if I'm buying a Coachbuilder shackle kit?
No — every Coachbuilder shackle kit for the 2007-2021 Tundra already ships with a graphite poly bushing kit for the rear leaf spring eyelets. This standalone kit is for replacing bushings that have worn after years of service, or for upgrading the eyelet bushings on their own without changing your shackles.
