Exterior Mods

Spring rate, shock versus strut, caster and bump steer, driveline angles, sway bars and bushings — defined from the engineering standard, plus five things people repeat that are not true.

Dynamic versus static load, what your roof is actually rated for, why a bed rack changes the problem, and the payload arithmetic the rack manufacturer never mentions.

What the airbag warnings actually say, where the weight lands, why rock sliders and step bars are not the same part, and the California bumper rule that probably does not apply to your truck.

Load rating, TPMS sensors, the spare that no longer matches, and who balanced the assembly — the four things nobody mentions at checkout on a wheel and tire package.

Leveling kit, body lift or suspension lift — what each one actually changes, what California Vehicle Code 24008.5 really limits, what breaks past three inches, and the same build on three budgets.

Offset, backspacing, bolt pattern, center bore and load rating explained in plain language, plus what aggressive offset actually costs you in wheel bearings and steering on a truck that hauls.

What California actually allows for window tint, why the 70% limit means 88% film, which film types reject heat instead of just looking dark, and where DIY makes sense.

Spot, flood, ditch, rock and bed lighting compared, how to wire auxiliary LED lighting with relays and proper fusing, and what the law says about running it on the road.

Vinyl film, trim dye, or removal? How to black out chrome grilles, mirror caps, window trim and badges in a driveway, and the two mistakes that make a chrome delete look cheap.
