is it too much spring?

[roughranger]

ok i am building a tough truck. i want to make it so that the wheels arent hitting the inner fenders and keep the axles from bottoming out on the crossmember when jumping. i put rear coils from a subaru justy inside of my stock springs. is this to much spring? i have practically new rancho shocks on it. thanks rough

...you put springs inside of a spring?

 

[roughranger]

yeah

 

[koda6966]

What did you hope to accomplish by doing this? A stiffer ride?

 

[metalmacguyver]

Koda, re-read the origional post. He wants to jump his truck. The answer is yes, he wants a stiffer ride once the suspension begins to compress.

i wanted to keep the suspension from bottoming out when landing a jump!!!!!!!!!!

 

[koda6966]

Um well.. jump it and see if it's too much.
If you land and it feels like you just hit a brick wall, its probably too much.

you are going to have a hard time finding the happy point between bottoming out and shredding your front end and hitting the ground and feeling like you just got ran through a haybaler.

as koda said, test it out. trial and error. then go as stiff as you think you can stomach on the landing

Dual (or even triple) shocks will help with the landings as well (you'll want something good & stiff on the compression stroke)

I take it this truck is stock

watch your coil buckets, the stockers in stock forum have been known to bend and crack with hard use and heavy spring rates.

a very high spring rate in the front can cause the truck to sky wheelie when jumping.and that will cause even more problems when you land back wheels first and the front end is slaped to the ground.

a old school cheap beater trick use to be to put tennis balls in the coil springs.think compression insert.sortsa like a air bump,but very rude.down fall is after a jump or two the balls are going to be dead.And you dont want to put in so many that it will cause a bind before the beams hit the bumps.as your coil buckets wold not be up to the task of taking the load of the truck landing on them.and worse case you could bend the frame inward that way too.
