Not sure there is such a thing. i.e. a model specific kit for this truck,most 'bag' kits are aimed at aftermarket front IFS and rear 4-link suspension set-ups.
Most kits for leaf spring set ups as far as I can work out lean more towards a 'helper' spring for overload situations.
Lowering 5-7" might get things a bit close to the chassis on a stock front beam/rear axle too.
You could do worse than give
Sid a call,he'll
steer you in the right direction.
