Long travel

[auhutchi]

I had mine on since break in. I was wondering what is it for. It's strengths and weakness (long travel rockers)

 

[Bartek]

it's for long travel of the wheels...
great for off road but sucks on road.

Have you thought about fitting the progeressive rockers yet ??


As to "Long Travel" rockers, They allow more travel of the suspension (most notable at the wheels as bartek states), whether that travel is up or down (to a restricted point at least). Long travel IS ideal for offroad situations, but if you plan on street running and off road running fit either of the other two rocker sets and see what suits your needs best. before you decide which to keep fitted.


THIS, IS AS PER THE REVO MANUAL ( : to you bartek, i got a revo & Revo 3.3 manual already !!!)

Also included are instructions for using the Long-
Travel rockers and springs supplied with Revo. The long travel rockers
allow extreme suspension travel for rock crawling and rough, large-scale
terrain. The long travel rockers allow the suspension to operate at its
extreme mechanical limits and is recommended for advanced users.

Suspension Tuning

Springs

The front and rear springs on Revo have different spring rates. The rear springs are about 20% stiffer than the front springs. The spring’s pre-load tension can be adjusted by turning the spring pre-load adjuster. Adjusting the pre-load changes the suspension sag. Suspension sag basically defines how much the suspension compresses when the truck is at rest. Adjust the pre-load so that the suspension compresses about one third of its full suspension travel (see illustration). If suspension sag is severe and requires a large increase of the spring pre-load to compensate, then a firmer spring should be used. Firmer springs (supplied) must be used when the Long Travel rocker arms are installed. Use a stiffer spring to reduce sag, reduce body lean, control brake dive, and provide a firmer, more responsive overall feel. If Revo is lightened significantly for racing applications, softer springs will be necessary to allow the suspension to sag properly. Heavier configurations will require stiffer springs. Ride height is adjusted by changing the length or position of the pushrods in the lower suspension arms. See the next section for ride height adjustments. The suspension sag and spring pre-load should be readjusted anytime the springs are removed and/or replaced. Optional springs available from Traxxas are listed below. Refer to your parts list for a complete part number listing. Higher rate springs are stiffer. Springs can be identified by dots of color on one end. ​

Ride Height Adjustment

The rocker arm suspension uses push rods on each suspension arm.
Changing the length and/or position of the push rod adjusts the ride height without affecting or compromising other suspension parameters. For example, you can raise and lower the ride height without changing up/down travel distribution, changing springs, or affecting your progressive rate. This feature is unique to Revo and is extremely beneficial in a racing environment where you can achieve a low center of gravity (by lowering the ride height) without losing any suspensio capability. Increasing the ride height will increase ground clearance for rough terrain.​

[Talk'n TRAX]

Thunder Tiger, had does one know if they need to replace their springs or shock oil? I've had my revo for 3 months and the only thing i have adjusted/changed on my shocks is pre-load and I've noticed that my revo is squatting lower than usual. My push rods are set at the highest ride height. I am using P2 rockers and have stock push rods in the rear and I think 90mm push rods in the front ( shorter than rear). If I adjust the pre- load in the front for max load, my front end still hits the ground. not sure what route to take.

 

[ThunderTiger]

check the shock oils first. then go grab your manual and read it, the answers are all in there.
