Polyurethane bushings are great for upper control arms, shackles, and even motor mounts. These bushings not only have a longer effective lifespan, but they also hold up better under the stresses that spirited driving can inflict on the original suspension bushings. They provide good vibration dampening compared to the firmer bushings such as delrin. We recommend using Probearing grease with polyurethane bushings for superior lubrication and to help prevent squeaks.

FAQ
Do these need grease?
Yes. Polyurethane needs grease to stay quiet and wear well. The helix grooves and face grooves are there to carry it. Grease the bore and both faces at install. We recommend one Poly Bushing Grease Packet per bushing.
Which size do I need?
Measure your housing and sleeve, then pick the matching option: 1.75" OD x 1" ID x .2" shoulder (G3650020-94BK) or 1.685" OD x 1" ID x .225" shoulder (G3C40023-88BK).
What's included?
(1) Polyurethane bushing. Order the quantity you need per pivot. Grease and inner sleeves are sold separately.
Poly vs Delrin vs SilentSpin?
Poly gives better vibration damping than firm Delrin and needs grease. Delrin is firmer with no deflection. SilentSpin is greaseless and maintenance-free.
How do I keep them from squeaking?
Squeaks usually mean the bushing is dry. Pull the pivot, clean out the dirt, and re-grease the bore and faces with poly-safe grease.
