BDS Suspension engineered this 5.5" lift kit with 4-link conversion for your 2013-2018 Ram 3500 gas truck, with clearance for up to 37" tires. Up front it runs gas-specific progressive-rate Pro-Ride coil springs, 4-link control arms with conversion mounts, a forged drop pitman arm and track bar drop bracket for steering correction, bump stops, brake line brackets and tuned FOX 2.5 Performance Elite shocks. The 4-link conversion uses high-strength 1/4" steel brackets and HD upper and lower control arms to correct axle positioning while limiting caster change through wheel travel. The rear uses a high-strength fabricated lift block, longer u-bolts and matching FOX 2.5 shocks.

Direct replacement for my J Deere GT225
Fit my John Deere GT225 as a direct replacement. It did need to be re-gapped before installation. I think the price was fair for two spark plugs, now I have a spare.

Fits well, sane quality as the oem installed
Works really well, it fits and matches the original spark plugs and very easy to install. Very affordable! It starts right up , quality is very good and didn't have to adjust the gap on spark plugs!

Fresh Spark Plug for the Mowing Season
Just what my push mower needed! Very compatible with my Craftsman M220 push mower. It was the right replacement part and workings just like the original brand B&S plug. Gap was correct right out of the box as my push mower fired right up first pull. Would recommend for anybody with a Craftsman M220.
