How can i get the rear of my truck to not sag so much

[xsavage3148]

I tried heavier oil and different pistons but I'm not getting the results i wanted. the back of my truck squats way too much when i give it full throttle.

Stiffen up the springs......

if you stiffen up the rear shocks, you're going to flip your truck more...the shocks are absorbing the torque during take-off...

if you aren't worried about that, try stiffer springs, and/or adding spacers to the shocks...but get read to buy a wheelie bar if you don't already have one 😀

My truck wont wheelie since i did the extended flm/mugen mid tank setup so i took the wheelie bar off. unfortunately there are no stiffer springs yet for the big bores so i guess i have to wait. i tried more spacers but then the rebound was worse. the truck pretty much touches the ground at full throttle so i wouldn't mind a little stiffer of a spring.

Yes there is different springs.... the longer springs on the big bores are really hellfire springs...:jamout:

But will a stiffer spring work with the same black smaller spring?

i don't see why it wouldnt.... 🙂

ANd then would i have to change oil or pistons to go with the stiffer spring? and how do i tell the stiffness of the spring?

on one end of the spring there is a paint stripe, the big bores come with pink. Pink=Med Soft..... there is a kit for the hellfire that hass all the different springs... i ordered one of the ebay just waiting for it in the mail......

oh i see now. so if i went to white that would be a little stiffer correct?

Yep the white springs are stiffer than the Pink springs....

Here is a link to that spring kit i was talking about....

OK i have my white springs now. rebound is still not how i want it. if i want faster rebound should i switch from the 1.6 piston to say the stock white one with the same 35 oil?

thanks for update, good to know

OK i swapped the pistons back to the white ones with same 35wt oil. with white springs. rebound isnt as fast as i would like but i think it might be good enough. i have to run the truck to really see how much the *** sags at full throttle. I'm just working on the hellfire shock mounts now.
