This Range Rover sold in September. The buyer never paid.

Good morning. Whatever happened at the polls last night, the convention floor in Las Vegas held its own vote this week, and 42-inch tires won every precinct.

The SEMA Show opened Tuesday with more than 2,000 brands and a Bronco that Ford fitted with 1,200 horsepower, for search and rescue. We'll walk the floor, run the numbers on what giant tires do to a truck, and follow the money into a $53 billion industry built on people who can't leave a car alone. First, a Range Rover that's back on the market through no fault of its own.

In today's newsletter, we'll get into:

Let’s roll.

A 1995 Land Rover Range Rover County Classic in Beluga Black over Sorrell Tan leather is back on Bring a Trailer, offered by a BaT Local Partner in Wheelersburg, Ohio, on behalf of its private owner. It shows 127,000 miles, bidding sits at $12,250 with no reserve, and it closes this afternoon at 1:31 PM ET. Whatever the top bid is at 1:31, that's the price.

You may have seen it before. The truck sold on BaT in September for $27,750, and the winning bidder never completed the purchase. That account has since been restricted. Of the two parties in that deal, the 31-year-old British SUV turned out to be the dependable one.

1995 was the last year for the original Range Rover in the U.S. Land Rover added "Classic" to the name so dealers could sell it alongside the all-new second-generation model, and the County Classic became the send-off.

This one has been through a lot since. In 2019, a Vermont shop took the body apart, repaired rust in the floorboards, and repainted it. The original 3.9-liter V8 came out and a 4.2 from a 1995 long-wheelbase Range Rover went in, soda-blasted and rebuilt with a three-angle valve job, a custom camshaft, and a performance ECU. The ZF four-speed automatic, the transfer case, and the torque converter were rebuilt at the same time, and the underside was coated in Waxoyl. The factory air suspension had already been swapped for coil springs under an earlier owner, which is the most common upgrade these trucks ever get. It also comes with five spare wheels, a quantity that suggests a long-term relationship.

The engine swap makes more sense than it sounds. The 3.9 and 4.2 share the same 94 mm bore, and the 4.2 gets its extra displacement from a longer stroke, 77 mm against 71 mm. That adds about a third of a liter, and in a long-stroke engine most of the gain shows up as low-end torque, which is what a heavy truck on all-terrain tires uses most.

The current owner bought it in 2019 and added about 1,000 miles. A July 2026 service replaced the rear differential, ignition components, front tie rod ends, the swivel ball and axle seals, and two window regulators. Those are routine wear items on a Classic, and FCP Euro carries them, which makes the next round of maintenance easier to plan than it was in 1995.

The disclosures are in the listing. Carfax shows front damage in December 2001 and another accident in November 2006, the paint has visible flaws, the seats show wear, and the truck has been registered in six states.

My call: $22,000 to $27,000, a little under where it landed in September.

Every November, the companies that make lift kits, wheels, superchargers, and seat covers take over the Las Vegas Convention Center to meet the shops and retailers who sell them. That's the SEMA Show (SEMA is the Specialty Equipment Market Association). It runs Tuesday through Friday, and for most of it you need a trade badge to get in. The public gets Friday, followed by a party called SEMA Fest.

This year's show passed 1 million net square feet with more than 2,000 brands. The automakers came too. Seven of them have booths: Ford, Harley-Davidson, Honda Racing Corporation, Mitsubishi, Mopar/Stellantis, Nissan, and Toyota. Mitsubishi is back for the first time since 2012 with a 2028 Outlander Diamond Trail Edition, which gets all-terrain tires and a new drive mode called Rock. Toyota brought five winter-ready "Snowhunter" trucks and five lifted "Woodland" models, one of which is a Sienna with over-fenders and a roof rack, the most optimistic thing anyone has ever done to a minivan.

Ford had the week's best tease. For two weeks it posted clips of a Bronco having its twin-turbo V6 hoisted out, and on Tuesday it showed what went in: Megazilla 2.0, a 7.3-liter V8 from the Super Duty family with a 3.0-liter Whipple supercharger, rated at more than 1,200 hp and more than 1,000 lb-ft. Ford calls it the most powerful crate engine any automaker has built. The truck is called the Frostwarden, it rides on 42-inch BFGoodrich tires, portal axles, and Dana 60s, and its backstory is Arctic search and rescue. Nobody stranded in the snow has ever been in this much of a hurry to be found.

The rest of the floor did its part:

A Bronco Raptor leaves the factory on 37-inch tires, already the biggest Ford fits to any Bronco. The Frostwarden steps up to 42s. Five more inches of rubber looks like a styling decision. To the rest of the truck, it rewrites the spec sheet.

Gearing. A bigger tire covers more ground per revolution, so it acts like a taller final drive. The Bronco Raptor's 4.70 axle ratio becomes an effective 4.14 on 42-inch tires (4.70 × 37 ÷ 42). Force at the contact patch is axle torque divided by tire radius, and the radius just grew 13.5%, so the same engine delivers about 12% less pull at the dirt.

Ford's fix is the portal axle. A portal hub puts a small gear set at each wheel: the axle shaft enters the hub high and drives the wheel through a reduction gear below it. That does two jobs at once. It multiplies torque at the wheel, buying back what the taller tire took, and it raises the axle housing for ground clearance. Ford hasn't published the Frostwarden's portal ratio.

Speed signal. The truck counts wheel revolutions and assumes a 37-inch tire. On 42s, an indicated 60 mph is about 68 in reality. The same error feeds the odometer, the ABS, and stability control, which all use wheel speed as their reference. Reprogramming the tire size is the cheapest line on the invoice.

Rotating mass. A 42-inch mud tire can weigh well over 100 pounds before the wheel, against roughly 70 for the factory tire. Rotational inertia scales with mass times radius squared, so heavier and larger compound each other: each corner ends up with about double the rotating inertia. The brakes have to absorb that energy on every stop, and they work through a longer lever, since the same brake torque produces about 12% less stopping force at the ground. Serious builds upgrade the brakes for this reason.

Driveline angles. Lifting a truck through the suspension changes the angle every driveline joint runs at. The rear driveshaft uses universal joints, and a U-joint running at an angle doesn't turn at constant speed. The output speeds up and slows down twice per revolution. At 6 degrees the swing is about ±0.5%. At 12 degrees it's about ±2.2%, roughly four times worse for double the angle, because the error grows with about the square of the angle. That fluctuation is the vibration owners feel at highway speed. Builders cancel it by setting the joints so the second one undoes the first, which is why lift kits ship with spacers and drop brackets. The front half-shafts use constant-velocity joints that handle angles better, though joint wear and boot life still suffer as the angle grows. Portal hubs sidestep part of this, because they raise the truck at the wheel and leave much of the suspension geometry where the factory put it.

In prototype validation work, a change to any rotating part reopens the test plan, because rotating mass reaches into braking, driveline loads, and calibration all at once. A tire swap like this one touches every item on that list in a single afternoon.

SEMA's own market research puts U.S. accessory and performance parts sales at $52.92 billion last year. About one in four vehicle owners bought something to personalize a car or truck, and more than half of those buyers were under 40.

Pickups carry the market. Owners spent more than $15 billion modifying them, about 30% of the total. Suspension products alone came to $3.15 billion and off-road and oversize tires another $2.23 billion, so the Bronco on Ford's stand is a rolling sample of the two biggest line items in the industry.

For most of the car business's history, the automaker made its money on the first sale and everything after belonged to somebody else. SEMA is where you can watch that change:

The logic is margin and loyalty. A factory-branded part can be ordered at the dealer, rolled into the loan, and installed in the dealer's own service bay with a factory parts warranty attached. The automaker gets paid again on a vehicle it already built, and the dealer gets the labor.

The age of the buyers matters just as much. A customer under 40 has several more vehicle purchases ahead of them, and an automaker that sells someone a lift kit at 28 has a decent shot at selling them the next truck at 35.

The independents still own nearly all of the floor. Of the more than 2,000 brands exhibiting, seven are automakers.

That's a wrap. See you Friday — same inbox, lower gear.
