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.
