In this episode of "Shock Talk," hosts Shane, Mike, and Junior explore the transformative power of Independent Front Suspension (IFS) in the realm of off-roading. They delve into the do's and don'ts of IFS builds and explain how IFS provides a competitive edge to off-road enthusiasts by enhancing traction and handling on rugged terrains. The hosts highlight how IFS's independent wheel movement allows for better ground contact, minimizing wheel lift and maximizing traction-a crucial feature for precision maneuvers in activities like rock crawling. Moreover, they shed light on IFS's prowess in desert off-roading, where its superior comfort, stability, and control offer a smoother ride over demanding landscapes.

I have a 4th gen 4runner, and I ended up with Bilstein 5100 on OME coils because I wanted a mild lift overall front and back for more up travel. I went with the lightest load coils OME offers, and for the front it works out OK. Front spring rate is only slightly above OEM, and the ride is awesome. The control over rough road is unbelievable compared to stock. However, even using the lightest coil OME offers, the 2895E, it was way oversprung in the rear. It does give a nimble feeling, but my stuff would literally jump in the trunk when going over speed bumps. I wish I knew you guys specifically paired the valving with factory spring rate.

For IFS is there a rule of thumb for at ride height the angle of the lower control arm?

@stevevonseggern6934 11 месяцев назад

Angle of lower will change the same degree as the upper when lifting an IFS. Rule of thumb would be to maintain the best geometry/caster angles without having to add additional components.

@kookertech 11 месяцев назад

@@stevevonseggern6934 That makes sense. Reviewing other people’s off road trucks or buggies that are heavily modified they seam to favor between 5 to 7 degrees if possible.

currently waiting on 8112 dsa+ and was curious about the spindle lift opposed to preloading the shock for the 2+ inches. what i’m assuming is preloading the coilovers will bring the ride zone farther up rather than a lift spindle and not having to do anything to the shock. will this allow the shock to work more freely with the spindle without the preload?

@stevevonseggern6934 11 месяцев назад

If the vehicle is 2wd and a spindle is offered, it would be a great option when lifting or lowering to maintain good geometry. However, the 8112 coilover technology would not benefit from removing all preload, since the internal JCO/RCO locations are very specific and require a certain amount of preload (stated in instructions) for proper function. Reducing or increasing preload past the stated recommendations will put you in a non-optimal ride zone which will engage JCO/RCO prematurely. Too much preload will engage RCO prematurely and not enough preload will keep the JCO in contact at low velocity.
