Two Hour Wonder: Putting The Fox In The PenthousePosted in How To: Suspension Brakes on April 20, 2017 0) (
Much like Barry Bonds career stats, this month’s One Hour Wonder comes with an asterisk. There’s actually two halves to this job that need to be done: one to each shock that is, and they each take about an hour.
RPG’s Corey Kausch says Ford didn’t want anyone to be able to change the stock ride height of the Raptor, so Ford asked Fox to change their normal design for the Gen 2 Raptor coilover shocks in that they wanted to have a single groove where the split rings hold the lower spring perch to the shock, instead of the three that the previous Fox shock-equipped Raptors had. You know, the ones where you could adjust the front suspension action by adding or removing preload to the spring.
Seemed like a good thing to be able to do to us, but Ford didn’t think so. We don’t know why Ford would want to make a change like that, but they did and Fox did what Ford asked as Ford’s an account they probably want to keep happy.
RPG saw an opportunity to upgrade this arrangement and did so with their new Spring Perch Collars. These billet aluminum collars take the place of the split wedges and anchor the lower spring perches. They also can raise the front end either 1.5 or 3 inches, depending on which Spring Perch Collar you went with.
This job can be handled in the comfort of your own garage, with the shocks still on the vehicle. Of course, you’ll need to use a spring compressor to accomplish this. We like to live dangerously, at least force others to do so, so we had the RPG crew do the “on the truck” install method. We did stand back a little just in case the compressor slipped off the spring and launched itself across the shop.
It happens, so use extreme caution when compressing the spring. No kidding.
Or, you can have the RPG crew do it for you (or a local shop). Either way, the benefit of being able to add preload to the spring is a good thing, and one that helps with fine-tuning the suspension. For more information on this part, give RPG a call.
