do any of you run landrum leaves? we are looking to switch brands,but the landrum #'s are a lot heavier than what we run now.
we run a stacked leaf on the lr and a mono with the coil on the housing rr.imca tires with 2450 wt. rule.
money is always tight to start the year,just like the rest of ya!!!,and i hate to buy the wrong springs.any set up help would be greatly appreciated,thanks for your help.

Wingnut we run multileaf now on both sides.Thinking about trying the coil over mono on the right rear;how do you like this set-up?

i started with 2 multis,but he people who that were winning had this setup,so what do you do?i copied them!!
being new to leaf springs,i could never get the car to loosen up,with the coil on rr that is easy to adjust either way.
i am still no expert on leafs,far from it,so any new discussions on here i try to learn something new!

landrum springs uses a different way to rate thier springs,example thier 175 spring is actually the same rate as an afco or howe 120 lb spring.i dont know how they come up with thier rates but they sure confuse racers.most mods use the 120 lb leafs as a starting point which would mean a 175 ib landrum.total weight and rear weight percentage isnt the only variables.you need enough spring for the wheel weight you run on that particular wheel.also track banking and speed plays a part in spring rate choice.

thanks heavy duty,
it didn't make much sense to see that the landrum started at 150,when others started so much lower.
going by the name heavy duty,i'm assuming that you are the one in kentucky that build lightning cars.i think i read where you at one time built a few leaf cars,if so did you ever use landrums? thanks for your help.

yes we did use them.we used the 20-230spd.the front eyes on landrums are narrower than everyone elses,so you have to make spacers.we used mostly afco and howe springs until we started having our own springs made.we had ours made in 7,8, or 9 inch arch so we could have 5" arch with the weight of the car on them at ride height.we still build a few leaf cars,and still think they are good for most people.everything runs in cycles,i remember a 4 link fad in the early to mid eighties,and then everyone went back to leafs.wait till bloomquist wins a big show in his leaf car and see how many guys go back to leafs after that.monkey see monkey do.i like the way a leaf car drives,they just are too much work changing and trying to get consistancy in rates.the new composite leafs will probably save racers money,if the sanctioning bodies get smart and approve them,but dont hold your breath.just look at the transmission deal.they dont always do the smart thing.

i'm back.i wanted to ask about your brand of springs.we may put togeather our second car and i may run two multis on it.do have have a web site,or literature on the springs you sell.
part of the reason i'm looking at a different spring is because i have a hard time trying to get rear ride height.even gone as far as using no lowering block on the lr and using the bottom hole on my shackles to get where it should be.thanks again for your help.

Wingnut try to get a hold of Rex Merrit. He ran these springs for years. They were his sponsor until he went to work for Bilstein. Rex is a great guy with a ton of wins in an IMCA mod. The last number I have for him is 417-743-4935 or try Bilstein. Good Luck!
