They're not, Dave said he's ramps not the best, said if would compress if we lifted the rear tire, I know if goes to full bump, you can see the shock hit the spring set flange thing on the drivers side, just kisses it.
And that's my point. Your coil would go solid BEFORE your bump stop even had a chance to compress at all. In other words, they are completely useless and your coils are most likely over compressed. Don't know what shop would recommend a lame setup like this and on purpose but I personally would steer clear of them.
Sorry, I did cycle without coils to confirm all travel used...
I don't doubt it. You just never took account that WITH coils installed, you would over compress them or worse - have them go SOLID before you could use all that travel. :naw:
...still interested in what bump extensions used for 35 and 37 tires
For the record, I never said anything about tire size. The only time tire size is a factor when it comes to bump stop extensions is when you're trying to prevent tire rub at a full flex. Again, the PRIMARY reason for bump stop extensions and ones that are about as tall as you have lift is to help prevent the over-compression of your coils. In other words, to help prevent them from getting squashed down to the point where they no longer return to their original height.
