Sport Equipment Package (RPO code =BYP) [73][edit]
In 1989, a Sport Equipment Package was available on either C/K1500 fleetside short-bed single cab models with the YE9 silverado interior trim package. The Sport Equipment Package featured a black grille with a red outlined bow-tie emblem, black moldings outlined in red, body color front and rear bumpers, black mirrors and "SPORT" identification decals on the box and on the tailgate. The box and tailgate decals were flanked by Chevy bow ties.

-2WD only models also received a black air dam with integrated fog lamps and chrome 15X7 wheels with specialized chromed plastic center caps.

-4WD only models also received black wheel flares, black tow hooks, 16–inch cast-aluminum wheels and additional 4x4 sport decals.

The BYP package was only available on trucks painted in solid red, white and black in 1989. It has been reported that the 89 sport was a limited production run set to determine how well the package would be received by consumers in the years to follow. There were no suspension or engine upgrades provided with any of the sport packages as this was an appearance only option. Suspension or any other upgrades or options are only determined by additional RPO codes. It has been rumored that only 5,400 BYP packaged trucks may have been produced in 1989.

In 1990, the Sport was re-introduced and carried on until 1994 along with the 454SS. GMC models could now be optioned with the Sport appearance package with their own unique decals and color combinations. The exterior mirrors became solid, low-profile aerodynamic manual units color matched to the body color. A ZQ8 Sport suspension package was now an available option for 2WD models which included Bilstein Shocks, 12:7:1 ratio steering and required 275/60R15 tires. In 1992 Blazer/Jimmy models could now be optioned with the BYP package. The Sport Equipment Package is the most frequently faked looks for the Chevrolet trucks but RPO decoding will reveal if it is a true "sport" or not.

454SS (RPO code = B4U)[edit]
In 1990, Chevrolet introduced a high-performance variant of the GMT400 under the Super Sport emblem called the 454SS. It was available only as a 2WD half-ton regular cab short box in Onyx Black only with a garnet red interior. The 454SS was powered by a 454 cu in (7.4 L) V8 producing 230 hp (172 kW) and 385 lb⋅ft (522 N⋅m).[74] A 3-speed automatic transmission (Turbo Hydra-Matic 400) and 3.73 rear axle ratio added to the truck's performance. The axle itself is unique, being a 14-bolt semi-floating unit which uses standard Chevrolet 5 on 5-inch wheels—the only factory-produced 14-bolt axle with such a wheel bolt pattern. The suspension was also upgraded with 32 mm (1.3 in) Bilstein gas-filled shock absorbers, a 32 mm (1.3 in) front stabilizer bar, and 12.7:1 fast-ratio steering gear assembly.

Unique exterior features included a front air dam with fog lights, special rims, decals displaying "454SS" on the bed sides, red trim emblems, and black painted grille, bumpers, and mirrors. The interior was also unique with a special plush Garnet Red cloth with black trim, high-back reclining sport bucket seats, and center console.

For 1991, a four-speed electronic automatic transmission (known as the 4L80E), 25 more horsepower, and even higher torque (405 lbs/ft at 2400 rpm) were added to the 454SS. The rear-axle ratio was also lowered to 4.10:1 for extra jolt off the line. On the dash was a tachometer, oddly omitted from 1990 models. Dual exhaust was also added during the '91-'93 model years.

The MSRP of the 1990 model was US$18,295 with a $550 destination charge. A total of 16,953 units were sold over the 4 years the 454SS was in production, with 1990, the first year of production, selling 13,748 units alone. The 454SS was discontinued after the 1993 model year.

In 1992–1993 other color options included Summit White and Victory Red, with multiple interior colour options. The rear quarter panel and tailgate decals also changed in 1992 to a more 'stylized' 'SS' and the Chevrolet sticker on the tailgate became much smaller and located on the corner area.

Hey thanks for passing that on. I didn't know they offered it with the K1500, and can't say that I've seen a C1500 sport trim in years.

I keep seeing a 454Ss driving around here...I really wouldn't mind having one.

If only they made the emblems say 350-SS, SS-350 kind of sounds like a boat name to me. :\
