Polyurethane vs Delrin Coil Spacers

[Irun]

I did some quick searches and didn't see anything specific here. Is a Delrin coil spacer a better alternative to polyurethane? Given Delrin is a plastic, it's a stiffer alternative to poly, while still having some energy/vibration absorption properties. I'm just not sure whether that's a plus of minus for a Jeep. FWIW, I'm looking at a small 1" spacer up front, to bring the nose up slightly. The spacers would be paired with 1" lift H&R springs.

I liked my aluminum spacers the most, so I would want whichever was the hardest material

I've looked at aluminum as well. Just wasn't sure if there was a downside to a rigid spacer I'm missing.

I have some poly teraflex spacers and they've deformed enough to let the coil get out of whack.

I've used Delrin spacers from Supreme Suspensions and prefer them over other materials. They won't compress or rust and have a lifetime warranty.

Precision CNC machined from High-Density Delrin, for superior durability and corrosion resistance. Delrin has the highest tensile strength of any thermoplastic and is the best material available for heavy duty applications, while still being light-weight and resistant to typical corrosion associated with off-roading.

None that I've noticed

A rigid spacer shouldn't be any different than the perch itself. Assuming you're still using the factory isolator, I see no reason it should be any different than stock.

On the other hand, poly seems to compress. Hard to measure precisely but looking at the bulging and deformation on my Daystar 3/4" spacers I'm almost certain I was not getting 3/4" of lift out of it.

I didn't run rear isolators with my aluminum spacers. Couldn't tell a difference with or without.

yeah that one is so thin it's hard to imagine it doing anything.

I was more thinking about the ~3/4" thick ones in the front. But I've never run without those, either, so . I just feel perfectly safe saying an otherwise stock perch and isolator arrangement can't be any worse for having a rigid spacer. Just like an aluminum body lift.

Exactly what I ordered, along with new springs, insulators and jounce bumpers.
